[Q] Problem with my Micro SD card

I just recently bought a Sandisk 32Gb class 10 microSD card. I got everything set up and I've been using it for a couple of days now.
Last night I just was using msn app on the phone then it just kinda kicked me off and I couldn't use the phone properly and it rebooted and said that the disk was either blank or it has files with different file allocation. ie fat 32 ntfs all that jazz.
I can not mount the card and i cannot format it again.
So scrounging around I found a SD card adapter for the computer and wacked that in the old port. It shows that it's there but it can not be opened.
I also can not view it's properties it just acts as if it's reading for ages.
Then it crashes explorer.
i tried opening it from command
it can't be opened but after opening the path for c becomes
c:\yujuju as if someone had typed it in.
i'm almost suspicious that it was a virus sent over the network through a program on my phone.
are there known viruses capable of making your micro sd cards unreadable?
if it's not a virus and it's just some kind of error on the micro sd card...
are there anyoptions for it? (has anyone made any recovery programs for SD cards you can download using forced mount methods or anything like that?)
I know i can send it back to the place of purchase but it means i have to pay for it to be sent to another state before they'll even look at it and if they don't think it's a manufacturer fault they'll charge me for it and the time spent trouble shooting. I'm a student and I can't really afford to do that

Just a quick note. I'm using cynogen 7.0.3 Desire
it is a HTC bravo. HBoot 6.93.1002
not sure if you'd need anymore detail than that..
please help :3

update// I just was looking around and I read about a website called recovery-filedotnet
and i downloaded the tool. When i try and scan the SD card the program crashes.
I used the demo version... I don't think this is going to end well. sigh.
Anyone with any knowledge that may help with out having to send it back to the company?

Hi,
Sorry, can't help you with recovering contents of your micro SD card. If you don't want to recover the SD card contents, have you tried formatting it on the PC (sorry, I couldn't tell from your posts whether you've tried that)?
There are also known to be many counterfeit micro SD cards out there. Basically, the counterfeit cards don't have the reported storage size, for example they may have 4GB instead of 32GB, so trying to write more than 4GB will result in data being overwritten (and probably trashing of file allocation tables).
I'm not saying yours is a counterfeit, but just something to be aware of.
You could check out h2testw which tests read/write performance, but also checks whether the SD card is the reported size (I think you'll need to format the SD card first, though).
Here's a link to a post I made using h2testsw on a micro SD card:

Have you attempted to delete the partitions in disk management?

You cannot open the card on a computer. If you try and open the drive explorer actually crashes and you have to open explorer again using run
If you try and open the drive using command prompt. The drive refuses to open.
You can't access properties of the device either.
I bought it from scorptec. An australian computer company.
wwwdotscorptecdotcomdotau

I opened the Microsoft Management Console and opened storage and when the card is connected to the PC it goes in an endles loop of searching for drives.
This is all very strange if you ask me.

To make it perfectly clear. I can not mount or format from the device, from clockwork mod using ROM manager. I can not mount or format from a PC using the GUI or the command prompt. Using Microsoft Management Console fails.
The other weird thing is my computer was stuffed this morning. I couldn't view the details of my computers properties. The wireless keyboard couldn't be used.
The CPU and stuff was listed as unkown.
I did a system restore to an earlier date logged in to safe mode
Even though it's restored successfully it doesn't recognise that my anti virus is running. I had to enable things in msconfig and my remote access was ENABLED!
I don't know if this was related.
But I'm feeling rather depressed after all this.
I've run spyware and anti virus and nothings picked up. So EH today sucks.
But lets just focus on the SD card for now hey? ^-^

Just to be absolutely certain it's the card, go get ubuntu live cd or gparted live cd, boot from it and try and see if the card works there. Imo it's fubar but last post questions it slightly. If you cannot get any life out of it in gparted send it back.

take russ18uk's advice, if that doesn't work, you'll just have to giveup and reformat it.

are they linux operating systems? Are you asking me to try and access the
device using a different? OS?
If so I'll wait till I'm in my programming class tomorrow and just boot the linux OS and see if it works.
Maybe ask my I.T teachers for assistance. But I think I knew I wasn't going to find a solution for this. I just can't afford to pay for postage costs at the moment. I've requested a returned warranty and I'll see what they ahve to say.
Sigh what a god awful day. @shakes tiny little micro SD card and yells [email protected]
(ironically I bought a Sandisk one beause they write the standards for MicroSD cards I believe haha, shot my self in the foot I wish I bought a kingston one now.)
@side note.. is this a picture of things to come? people come to me with computer problems and as a tech when i can't work things out i'll say ever cuss word under the sun in anger? lol i hope there's no customers around when i'm working XD maybe i should go get some anger management classes

Thanks to all who posted replies. Looks like I'll be sending the card back to the company I bought it from. poop!

[Q] Need MicroSD card help

I need help with what my TF700T is doing with my 32 gb MicroSD card.
I bought a good quality card and inserted it. No problems.
I connected my TF700T to my Windows computer via the. AUSUS USB cable
No problem, Windows recognized two different drives.
I added some folders to my MicroSD card and copied some music and video to it.
Put the card back in.
Then I noticed something weird.
The TF700T created a mst/SDCARD/ folder and it thinks that is where my MicroSD card is, but those files and folders are really on the internal.
My MicroSD card is under the /removable/MicroSD/ folder, that it thinks is on the internal Memory.
Do I have to re-format or rename my MicroSD card?
Thanks,
Jon

I'm a bit confused by your description. I don't know what the prefix mst means. If you are on ICS your micro sd should be at Removable and your internal storage should be called Sdcard (it changes with Jellybean). If the files you added to your microsd are actually on internal sdcard, maybe you made a mistake and copied them to the wrong drive in windows. Or did you create nested folders?

+1 sounds like you copied them to the wrong card.
/mnt/sdcard is the internal memory.
/removable/microsd is the external sd card.

what you describe in your original post is what the Infinity does when you have an SDHC/SDXC card installed. You don't need to format it.
I would just adding that seeing SD Card and Removable was just odd labeling, compared to other mobile devices because we're not use to thinking of storage build into a device as an SD Card. Although, I will say it's accurate because we can use it as such. The removable is accurate because we can remove that storage.
Hopefully that makes more sense now. It's perfectly clear in my head, LOL.

Thank you for your thoughts. Maybe it is mybrain, but I don't understand it, and it does cause issues for me.
The crd inserted in my Asus TF700T is a MicroSD card.
I can, if I choose to, insert a SD card in my docking station/keyboard, but I have not done that yet.
I don't understand what you mean by odd labeling compared to other devices? Personally, I never buy a device that does not have an expansion card. This goes back to Palm devices as well as my Samsung Tablet and my Cowan portable multimedia devices. Also my digital cameras.
If I go to do a backup that is supposed to go to my microSD card, it will look to backup it up to the Internal storage, in the /mnt/sdcard/......./ folder. It won't look at the expansion card.
Some applications see it, some don't.
There is some sort of confusion how the TF700T thinks where the microSD card is and if ie t exists.
When I first got the TF700T, I did not have an expansion card in it. I put it in about a week after I started using it. Could it be that because I put it in after starting to use it, it got confused and created this infrustructure of folders on the Internal drive thinking that there is an external drive ?
In the file directory, I cannot get it to change things so that when I go to mymusic or audio, to look at my microsd card, which is where I store my audio.
I am really confused. If I plug it into a PC, while the microsd card is istalled, Windows sees it properly and it creates two virtual drives that I can get into with Windows Explorer, no problem.
Something is messed up, but I don't know what it is.
Thank you,
Jon

Using ES File Explorer, you can see
This is at the root directory. The SDCard is the internal storage. Removable my SDXC card.
As for your music, it may be more an issue with the music you're using. I have encountered a problem with some apps where I cannot access SDHC/XC card. One example is Docs2Go. It won't go to the root directory on the local file selection, just do to /SDCard/, or in other words, just to top internal storage directory. I can open up the files using ES explorer directly and choosing the appropriate app to launch.
So you may want to use your file explorer/browser app, suck as ES explore, File Explorer, and so forth, and see if you can access your SDHC card while on the Infinity. I haven't loaded music on my SDXC card, or video files. I know I was able to access video on my previous SDHC card I had installed with MoboPlayer.
Hopefully that helps. All my answers on based on using the tablet only, no dock since I don't own it. As based on previous comments, which you only confirmed, I assumed you were familiar enough with having SDHC cards in mobile devices and how it worked. Thus, to me it looked more like an issue of know where to look.

[App] "FolderMount" Move Game Data to Ext. SDCard - Apps2SD alternative!

I don't know if this mentioned yet, but you might be aware that you can't move apps to your ext. SD Card to free up space on your phone.
For some reasons Apps2SD doesn't seem to work on Samsung phones.
After doing a bit of browsing/research I came across an app called "FolderMount." [Requires Root]
This works by mounting folders in your ext. SDcard to your internal SD Card, fooling your device into thinking your external storage is part of your internal storage. This way you can move all your game data (or any other files that can only stay on your internal SD) to your MicroSD card.
Here is a quote by the developer:
madmack said:
Today some apps store big files over the internal SD card (e.g. Games, Podcasts, Offline RSS feeds, Pictures, Offline navigation software). Typically users have a small internal sd card size (~16GB) while the external SD is a lot bigger (~32-64GB). Most of these apps don't have an option to use the external SD card to store data so they starve your internal SD card memory. I'm bringing this solution to fix this issue. In my case, I use this app to mount offline navigation software and some GameLoft games (NFS anyone?).
Doesn't this do the same thing as previous apps?
There are a few apps that already do this. However, my app differs in that:
a) Some of the existing apps aren't maintained anymore. FolderMount will be maintained by me as we go forward.
b) While most of the previous apps work properly in most cases, I found them not very intuitive to setup initially and were lacking some necessary "sanity checks" before linking folders. I intend to keep this app as intuitive and bug free as possible.
c) Support for Android 4.2.2! No app will currently do that for you, so here it is. (dev talk: this uses the debuggerd service trick to get it to work).

Folder Mount Reboots
Hello, My name is Darren and this is my first post, please go easy on me...
Could not ask this on FolderMount thread in Dev so hopefully can find help here.
I have FM Pro installed on I9505 and tried to created simple link of pictures (/storage/emulated/0/Pictures to /storage/extSdCard/Pictures) followed the FM prompts and it appeared all was good, then phone rebooted and continued to reboot for about 5 to 6 times then come good. Tried power off restart and cycle started again. Tried once more and all come good, no reboots , green pin and files are being stored on ext card.
Phone was Telstra branded (I9505XXUAMDE) now running djembey Pre Rooted Knox Free XXUAMDM. Could basic root access nature of this ROM be the cause of multiple reboots?
Kind regards Darren

For anyone who wants a quick tutorial on how to set this up:
Let's use Modern Combat 4 as an example for this-
Once you download Modern Combat, it stores all of its data on your internal SDcard in the following location:
/Android/obb/com.gameloft.android.ANMP.GloftM4HM
This folder is somewhere around 2GB i believe, or something like that.
The goal FolderMount is to move the above folder to your external MicroSD, but at the same time, fool your phone into thinking that the folder data is still in the internal drive.
To do this, do the following;
Download and install FolderMouint and give it root permissions.
Start the applications and click at on the "+".
For Name, Put in Modern Combat 4
For Source, chose Android -> obb -> com.gameloft.android.ANMP.GloftM4HM and press the checkmark button at the top.
You will get a message saying the following
"Would you like me to create the destination folder automatically?..blah blah blah"
Just choose yes.
Now press the Check mark button at the top again. It will start to move all the files to your external MicroSD card.
Once that has been completed, in the main FolderMount screen, you will see a little pin beside "Modern Combay 4". Press that and it will mount your folders together and it should work!
Sorry, I kind of rushed through this.

Press the three dots beside the "+" button and you should have an option to buy premium.

I dont understand... did everything as told, the app worked aswell.. but as i can see it only copied data from sd to external sd.. the original game data remains at the internal sd card, thus i have not received any free space??

What is the best way to get apps to work on it?
Some apps say "Move to SD Card"
And after you move them it shows as "Move to Device"
But on Google Play Music the option to Move to SD Card is grayed out
Another interesting note, the Google Play Music app version on my Joying is the same as the version on my Samsung S7 Edge, but the "Storage Location" option is missing on Joying
Joying

I am downloading my Playlist from Google Play Music on the Joying so I don't have to use data.

Honestly, dont bother with the rom that it ships with. Its crap. The custom rom is better but its still not good.
you cant move play music because its a system app. If you dont want to use a custom rom then root and use titanium backup to change play music or uninstall it and reinstall from playstore.

Can you explain this a little more? How would i use titanium backup to change play music? I did install Google Play Music from the Play Store, it didn't come with the head unit. I dont really need the whole app on the SD card, I just want it to store the music it downloads on the sd card, which is how it works on my Samsung S7 Edge. That may be an Android 6.0 feature though, I'm not sure.

Did you just plug it in and it worked? Did you have to do something special?
I'm having issues with Plex and US Topo maps saving/caching to the external sd myself. I'm going to try rooting and installing Apps2SD and I'll let you know what happens.
I'm also going to try to add some swap space since it's pretty universally accepted that this unit doesn't have enough ram. I would like to believe the onboard NAND flash is faster than an SD card but I've not found that to always be the case. Some of the premium sd brands can have really fast transfer speeds 80-90mb/s and you get speed boost by using them as swap. We'll see. Keep in mind this only helps out with inactive applications. The Android application life cycle is supposed to be a fancy form of swapping but I've found lots of apps don't properly use the technology. Swapping avoids that by saving the entire RAM state of the application to swap when inactive, so when you switch back things are a bit quicker because the entire state loads from swap not just the bits that were bundled via the app.
I have a RK3188 and I saw a review that just ripped it to shreds but honestly I'm not having any big speed issues with it so far. All of mine are based on software things like the inability to pair with anything not named ODBII. And this issue with the SD card.
I've considered removing the goofy home screen animation for good measure but have yet to pull the trigger.
Now to figure out how to properly root it.

When I plugged in the 128 GB at first it did not recognize it. I went to Storage in Settings and Erased that card, then Mounted it, and it worked.
however I still have the issue of not moving app data to external SD cards. I love Google Play Music, but just can't find a good way to move that offline storage there. So I'm currently trying Slacker and Spotify. I will report back with my findings.
I tried what claims to be the original App2sd, AppMgr III:
https://play.google.com/store/apps/details?id=com.a0soft.gphone.app2sd&hl=en
it is very user friendly, and just shows which apps can be moved and which can't, but I dont know that it really does anything other than that Move to SD option in the App settings menu
I also tried Link2Sd:
https://play.google.com/store/apps/details?id=com.buak.Link2SD&hl=en
but to use the full options you need the paid version, but you also have to already have the SD card partioned properly. Whicn Link2sd can't do. Also didn't look like there was really a way to do what I really wanted. I dont want to sacrifice speed for storage. So ideally, I want the app on the internal, and just the offline songs on the exteranl, which is how my Samsung S7 Edge lets me do it
So i went to this App2sd one:
https://play.google.com/store/apps/details?id=in.co.pricealert.apps2sd&hl=en
And it has a great interface and a lot of features, such as allowing you to partition a card from the app. But I didn't know what sizes to use for optimal performance or what to use for the 2nd partition. Still trying to find some guide that isn't several years old.
I did remove that 128GB card for a 64GB Samsung Pro+, cause it has faster read/write speeds

OK! After a day and a night of bricking rooting and flashing I found a solution.
com.devasque.fmount (can't post a link... too new on xda forums.) But an app named FolderMount [ROOT]
Foldermount. I'll save the details of how I got there for my review thread, but in short if you can root your device and install foldermount. Then if you can find the directory where the offline music is currently being stored, you can move it to the external storage. I'm currently running it with the Malaysk RK3188 firmware version 4 and it's looking good so far.
I'm doing this with Plex and US Topo maps now with no serious issue between last night and my drive in today and I've confirmed that it is indeed saving the offline data to the correct folder on the SD card.
The external sds are mounted at /mnt/external_sd and /mnt/external_sd2. GPS, and SD respectively. Ideally, when you set it up to send to one of those devices it would be wise to allow it to automatically create the folder. Without any tweaking it was smart enough to see the mount points as well.

i ended up bailing on Google Play Music and going to Spotify. Same price for the family plan, and it has the options for saving to SD card available, no tweaks required:
Interface looks good too:
The horizontal interface for GPM is kind of lame, these next two are from my phone, but it is basically the same for the Joying, I just didn't take pics:
Google Play Music
Spotify

Glad to see you found a solution. Unfortunately, I doubt this app will be the only situation where you have this issue. I've already used FolderMount to successfully redirect google maps cache, US topo maps, Plex, and a few others. I also confirmed that it is saving the cached data to the correct location. Total boot time for those apps can be a bit longer (you have to wait for the toaster popup saying they've been redirected but we're talking about seconds not minutes so it's a sacrifice that wasn't too hard to make.

SD Card & Adoptable Storage on G7 Power: Setup info + Questions

I have the US version G7 power with 3/32 GB memory. I knew I would fill that 32 GB up right away, and did. But no problem--just put a card in the SD card slot, move things over, and all is well.
In working through that, I realized there are quite a lot of options and documentation on them is not that easy to find. So I though it would be helpful to create a thread with resources, information, and questions asked and answered.
FORMATTING SD CARD AS ADOPTABLE, PORTABLE, OR SPLIT BETWEEN THE TWO
When I put my the card in, I realized you can format the card as portable, adoptable, or split between the two.
So I have a 256 GB SD card and formatted split: 50 GB adoptable, 206 GB portable.
You can reformat an SD card as adoptable or as portable by installing it and then going to Settings/Storage. Note: Reformatting will erase the card and all information on it.
If you want to split the card between adoptable and portable, you'll have to follow instructions like these: https://stackoverflow.com/questions...sd-card-into-internal-storage-via-adb-command
WHAT IS ADOPTABLE VS PORTABLE MEMORY
Adoptable memory is supposed to act almost as ordinary internal memory on your device, but it is linked to your device and will be erased if you factory reset your device, or install a new ROM etc. It is encrypted and can't be read by any external device--or even your own device after factory reset, installing a new ROM, etc.
Most guides to Adoptable Memory give dire warnings that you will lose all contents of the Adoptable Memory if you do a factory reset, update your Rom, etc. This is true--but simply makes it the equivalent of your device's internal memory, which is also wiped in those same situations.
Portable memory is the the 'ordinary' type of SD card storage we are accustomed to on an Android phone: You can save files to it, but usually not apps. You can just pop the card into any computer or another phone and read anything off of it.
Splitting the SD card between portable & adoptable seems a good compromise to me: It gives you a good-sized portion of internal memory (32 GB built in plus 50 GB adoptable, in my case) while still leaving you 205 GB as portable memory that works like a regular SD card.

Short explanation of adoptable storage
Once you format the SD as described above, you can go into Settings/Storage and you'll see something like this:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
For some reason, the internal partition lists the full size of the SD card but 205 GB (the portable partition) is listed as "system".
When you load a new app, supposedly it will load onto either internal storage or SD Card/adoptable, whichever has more space (for apps that can be installed in either location--some apps seem to require being installed on internal storage).
If you set up ADB, you can issue commands like these to control where apps are installed:
adb shell pm get-install-location Gets current install location
adb shell pm set-install-location 0 Sets current install location to auto (install to internal or adoptable, whichever has most empty space)
adb shell pm set-install-location 1 Force install apps to internal memory
adb shell pm set-install-location 2 Force install apps to adoptable/SD Card
If you have root you can just execute the same shell commands in a terminal on your phone.
The Questions/Problems/Issues with Adoptable Storage
So this brings me to my questions:
Generally this option seems to be very poorly documented. You can find guides, such as the ones I've linked to above, that tell you how to set it up. But nothing that will give much detail beyond that--how Adoptable Storage really works on the phone in detail. Any links, guides, detailed information about using this feature?
Specifically, is there anything the user needs to do to use or manage this adoptable internal memory space?
Can you just set it and forget it, assuming you have another extra 50 GB (or whatever) of internal memory and the phone and apps will just figure it out?
If you click on SanDisk SD Card (internal Partition) in settings, there is an option to "Migrate data". Once you do that, there is an option in Internal Storage to "Migrate Data" which presumably migrates it all back, if there is room. I did the first Migrate Data after creating the Adoptable Memory on the SD Card and it seems to migrate some data and apps from internal storage to the SD Card adoptable storage. It migrated a relatively small fraction of all data--perhaps 1/3? So is that necessary, helpful, not helpful?
I went into Settings/Apps and found a number of apps that were moved to SD Card, but also a number that list themselves as potentially able to move to SD card, but not moved. But every time I click the button to move those, tries to move and gets mostly through the procedure, but finally returns "Couldn't move app. Internal error." The app stays on the internal storage. Is there any way to fix this problem (or does it even need to be fixed?)
When you take a TWRP Nandroid backup, does it include the Adoptable Storage apps & data?
Answer: If your entire SD card is adoptable storage, then TWRP should backup apps on the adoptable storage.
However, if you are set up with a mixed adoptable/portable SD card then TWRP seems to miss the adoptable partition. It doesn't back up those apps. A suggestion would be to use Titanium Backup to back up those apps & data.

Although my phone is 4gb / 64gb, I used to have many devices with 32gb. I have no idea how people fill up their internal memory (provided they have SD card). I keep all my music, pictures, videos, and documents on the SD card. Only apps go on internal memory. I suppose some may install an excessive amount of apps (why?), I've got everything I need (could even do away with some) and only used 21 of the 64gb I have.

My previous device was 64 GB but with no slot for an extra SD. So 64 GB was tons of space for a few years . . . until it wasn't.
Of course, a bunch of that was music, sound files, other large media type files.
When I moved to the G7 Power I actually went through my app list with a somewhat fine-toothed comb, but even with that winnowing I probably came in with 24 GB of the 32 filled, right off the bat.
Right now I've got 32.2 GB in the internal storage, and that is with all music, videos, and other such things moved to the portable SD storage.
And as I said before, that is with some effort at winnowing things down.
Why? Well in general it's none of anyone's business why, but first off, the device was pushing 20GB straight from the factory if I recall, just the operating system itself takes 11GB, there are a few more GB of pre-installed system apps that I don't really need but can't easily get rid of, and some more that actually are useful.
On top of that I have a couple of large apps that I like and use daily, I'm interested in programming so there is a whole set of apps that comes with that, I'm interested in photography so there is a whole set of apps that comes with that, I'm interested in music so there is a whole set of apps that comes with that, I use the phone for work so there is a whole very large set of apps that comes with that, and so on for a few more interests and hobbies.
If you use your phone to text and read an email, look at Facebook at take a snapshot, then yeah, you're phone will look very, very different from mine.
In short, different strokes for different folks.
Why I'm bringing this up now is, if you're putting in a 128 GB or 256 GB SD card in the phone now, which is a very sensible thing to be doing, then you'll do yourself a favor thinking through how much space you do want to reserve on that card for this Adoptable internal memory.
Because in 6, 12, or 18 months going back to increase the storage you set aside for Adoptable memory from 16 to 32 or 48 or 64 GB is going to take a bunch of hours and screwing around. To make the change you'll have to wipe the card, so you'll need to back up & restore everything on the portable side and then also figure out how to back up all & restore all the apps & data on the Adoptable side.
Better to think it through a little now and make sure to reserve plenty of space rather than too little space.
In fact I reserved about 50 GB in mine for Adoptable Storage and I wish I'd gone a bit higher--at least 64 GB or maybe even 80 or 90 GB.
That's very little off the top of a 256 GB SD card but leaves you with a lot more options on down the line.
And hopefully most of that Adoptable storage will indeed go unused most of the time, but it's better to leave a relative lot of headroom on your system than always have it bumping up against the limits.

Snooping a round some more today, I found what appears to be the answer to those three questions I had:
> Can you just set it and forget it
> "Couldn't move app. Internal error."
> If you click on SanDisk SD Card (internal Partition) in settings, there is an option to "Migrate data". . . . is that necessary, helpful, not helpful?
The answers are in the Gadget Guide Online Adoptable Storage set guide, which is really thorough.
The short answers are:
You can (and should) just set it and forget it
The reason you can't move things to the SD card adoptable storage manually is because Android is managing it automatically [[UPDATE: This is incorrect: Android does manage the process automatically but if you have a "Change" button under the settings/apps/specific app/storage, you should be able to tap that and change the card from internal to SDCard/adoptable. See more details in post below.]]
Doing the migrate data procedure is essential--either at the time of creating the Adoptable Storage or (as soon as possible) later, via the "Migrate Data" button.
In detail:
After the micro SD card is formatted, you are given the option to move some files to micro SD card.
Please note, when you choose to use micro SD card as internal storage, you cannot control which files are saved in SD card, and which files are saved in the phone storage.
It will be always decided by the system based on many factors, for example, available phone storage and file type.
You can choose to move them now, or move them later.
You should always choose” Move now”.

If you don't choose "Move Now" just at that time, you can go into Settings/Storage, click your Adoptable Storage partitition, and in settings ('...') choose "Migrate data". This seems to engage the same routine.

Really Nice write up on Adoptable Storage
Here are a few pointers ive bumped into using adoptable storage on my kids E4+ and now on her G7 Power
1. try to use a fast sd card(obviously) im currently using a 64 gb A2-rated Sandisk even though the phone technically cant use that A2 speed
2. I did the 25% 75% split for her which added 16gb to Her "internal" and a solid for her 48gb external
3. I did NOT migrate data i did it manually since in her case she has like 10gb in just games so i moved the games to the "internal sd card" manually which allows all her true phone apps data etc to remain in the faster phone side of memory and keeps around 8GB free in the phone memory.
4. Set Titanium to backup All external data and it saves to the "Portable/External" portion of her Card
5 Her E4+ smoked the card twice where she lost all her games etc ..... Titanium made me look great in her eyes when I restored her stuff. ( takes time BUT worth it)
6. Go into developer options and set "allow apps on external" it may help with errors when moving some apps
This is for me and is what works for my kid who loves games on her phone..... 1 such game has a 3.1gb backup file i was totally shocked by this BUT whatever.....lol

UPDATE: Now that I have reinstalled the system, I can in fact move apps from SDCard (adopted) to internal or vice-versa, for many or most apps.
The fact that I couldn't do so before without receiving an error message was an indication the system or adoptable storage device was messed up somehow.

TWRP Nandroid backsup & Adoptable Storage
So I ran into another issue regarding adoptable storage: On my device, when I take a Nandroid backup of DATA using TWRP, the apps stored on the adoptable storage are not backed up.
Checking it out more, here is what I found:
If your entire SD card is adoptable storage, then TWRP should backup apps on the adoptable storage. (This is not 100% checked as I don't have this setup to test. But the TWRP developers swear it works.)
However, if you are set up with a mixed adoptable/portable SD card then TWRP seems to miss the adoptable partition. It doesn't back up those apps. A suggestion would be to use Titanium Backup to back up those apps & data.
This post summarizes this and more related issues.
