Adopting internal storage results in corrupt storage - Shield Tablet Q&A, Help & Troubleshooting

I have recently got a Shield Tablet and I have attempted to add a 128GB to the internal storage but every time I go through the adoption process to bring it into internal, it formats it and results in it being corrupted? The sdcard is brand new.
Tablet is on Marshmallow.

I am having the same issue with the Shield tablet and a 128g sd card. I can use as portable, but trying to adopt as internal storage always returns the "damaged" partition after formatting and starting the moving process. I have tried formatting as ext4 in a PC first as recommended by others to no avail. If anyone is able to get this working please post your fix.

Found the below "Notes" on Nvidia's site. Looks like you'll have to format NTFS on your PC. Some PCs will not allow you that option out of the box, but you can easily change Windows' built-in formatter's options to allow it to format NTFS. The settings are somewhat hidden. To enable it, open up Device Manager and find your micro-SD card, go to the Properties -> Policies tab and then choose "Optimize for performance". Once you've done this, you'll see the NTFS option in the format dialog. Just make sure you "Eject" the card properly, as it seems it's more easily corrupted if not ejected properly.
NOTES:
The ability to move data to SD card is variable for select*apps*and games. Onlyapps*that developers have opted in as moveable to external storage can be moved.
The SHIELD tablet K1 only supports writing to FAT32 and NTFS formatted cards.
64*GB*(or higher) microSD cards – Android does not support the exFAT file system out-of-the-box. Because the standard FAT32 file system does NOT support partitions greater than 32*GB*by default, 64*GB*cards come pre-formatted as exFAT. If you want to use a 64*GB*microSD with the SHIELD tablet K1, it has to be converted to a file system format that is supported by stock Android, which in this case is NTFS. This can be done using a PC.
Android KitKat significantly changes the way applications are allowed to use SD cards. If you use SD Card to store data, please read here for further details."

Hey, I have a similar problem but wanted some opinions.
Received my new K1 and updated to MM and everything is cool. Installed PNY 64GB (10 class) and chose the integrated storage option. The K1 sees the storage and I'm able to move apps to it. My problem is that new apps cannot download due to no storage. The message "whatever app cannot be downloaded. Install a SD CARD......something, something" (sorry, I'm at work).
Will formatting my sd card to FAT32 or NTFS fix this or is there something else wrong? I haven't seen any messages or errors regarding corruption and the sd card is working.
Thanks for any helpful suggestions!

When my 64Gb card was formatted exFat as it came stock, i had the same issue. I'm on LP. I had an almost empty card inserted, other than some mp3 files, and kept getting the message that my storage was full and that i need to delete some apps. I've since formatted it NTFS but i have not checked to see if items are being sent to the external SD. Don't have my tablet with me right now to check, but i wanted to reply to you that you were not alone in seeing the out of room message.

I had my PNY 64GB formatted with exFAT and it worked ok. I've switched to adopted storage and that worked too. But I saw other glitches with internal storage, such as MTP not seeing all files/folders even after reboot. I think "adopted storage" is buggy in general currently. It's also quite slow. Not impressed.
I prefer the Move to SD of Lollipop and Kitkat.

Do we already have a fix/workaround for this? I have a K1 (with the latest OTA 1.2) and 64GV Samsung Evo, formatting the sd card as adoptive storage still says corrupted. I already tried formatting it as Fat32/NTFS but to no avail.

I also couldn't get adopted storage to work.
The best fix for me is not using adopted storage
Instead I use an app called FolderMount which simply creates a symbolic link (is this the correcton term?) on the device's internal storage for whatever folder/file you like. It integrates moving data and managing it as well making the process as easy as it gets though you can of course do the same thing manually as it's using linux operations to do these things.
After you make the symbolic link when apps look for the data in the usual place on internal storage they "see" it but the data is actually whereever the symbolic link points to ie. on your external SD card.

Not found any real workaround for this it makes the tablet a bit of a dud

Caveats: I actually haven't tried it on Marshmallow since I went back to LP however I cannot see any reason that FolderMount will not work as it's using underlying Linux operations to do all the work. But YMMV.
I like this approach since you can move any folder from internal storage to microSD which makes it very flexible. For example you could move:
/Download
/Images/DCIM
/Android/obb
/Android/data
/where you store recorded videos/
and never worry about internal storage again (until you run out of microSD of course lel)
Or whatever you wanted.

FolderMount from the Play Store is not working on MM due to security changes.
There is a beta version that fixes it for some devices. Best to read the official thread here: http://forum.xda-developers.com/showthread.php?t=2192122

There's a problem with cards 64GB and up. I managed to format as internal storage a 32GB one, had no succes with 64 and 128 ones

I couldn't get portable storage to work on the stock MM RoW LTE rom. It works perfectly fine on all the custom roms I've tried (Bliss, Temasek, RR, etc) but none of those have LTE so for me it's either or if I want to use a MM rom. Otherwise, I'd have to use a LP rom for both to work...

I've hit this issue using the RR rom with my 128gb SD. But then if I keep the card in portable mode, I have those permission issues with my emulators. Has anyone got any suggestions or recommendations?
I've so far tried xInternalSD, SDFix and FolderMount with no success and I don't want to do that solution where I have to adjust the permission xml of all my apps. Its micromanagement I don't want.

I just have to use fat32 to get my 128gb card to work.

To work as adopted storage or portable storage? Because mine is working in portable mode, just has write to SD permissions issues for any apps not updated to deal with MM's new OTT security requirements on External SD's (which is most apps to be honest).

Adopted storage, I only tried it once but didn't like it so using portable.

Being Fat32 initially shouldn't have made a difference, because the card is reformatted to ext4 when its made into adopted storage and the tablet just seems incapable of reading an ext4 encrypted SD Card, so it comes up as corrupted.
What brand and model is your 128gb micro sd? And was it the stock rom you did it on? I'm using a Sandisk Ultra myself, and this definately does not work.

It's been awhile so I don't recall all the things I've tried nor the roms. All I know is I got it to it to work once. Think I have a SanDisk something. Just wasn't worth it in the end to me. If you're trying to get it to work, doesn't hurt to try. Stranger things have worked to fix issues in android.

[Q] Sd card problems on Nook tablet Root

I just rooted my Nook Tablet and everything seemed to install okay. The problem is that when I download a app like MX video player or andftp, they give me an error message saying that permissions are denied to this location. The MX video player will not even open because it says that "SD card is not present". Has anyone else had this problem? And how can I fix this? I followed this instructions. http://forum.xda-developers.com/showthread.php?t=1354487
Thanks
is the sdcard storage usable?
use a filemanager of your choice and browse to /mnt/sdcard
Thats the thing. There is no extra sd card. I am just trying to use the internal l memory.
The internal memory is called sdcard usually.
Check "/mnt/sdcard" that should be the internal memory.
I used a filer manager to view that folder and the manager says that the sd card is not mounted. Also the permissions on the folder are d --. How do I allow programs to use /mnt/sdcard?
Has anyone else had this problem with their nook? I can barely use any appear after rooting.
I have the same problem =(. I want to use the internal memory but whenever i download it says "An SD card is required to download *******.apk."
Exact same issue I am having. I will probably just return it and try something else.
I think this post is the answer to our problems.

I have the Nook Table. It is rooted, with superuser and root explorer on it. I put a 32GB SD Card into it. The B&N Storage avail is 11.87GB. The B&N settings shows the "Other Storage Avail" is 1GB. The B&N Storage sees the SD Card with 116MB avail.
When I check with the root explorer, it also shows the SD card size as 116MB. When I try to install a file from the market larger than 116MB, it says not enough room. Why can't I see and use the full 32GB?
Any suggestions as to how I fix this would be appreciated.
Cool. So do you know how to get access to the 11 GB that is on there?
As far as I can see, the Nook automatically puts user input data, such as My Files into that area. When I got into My Files, it shows 120MB used, 1004MB remaining.

I know that the 1 GB area gets used, but how do we gain access to the nooks 11GB memory location?
If you open the settings, device info, you will see "B&N Content Storage Available (for items purchased from B&N.)" So B&N downloads only go there.
I used the nook in native mode to upload a book to B&N Books, but I don't remember how I did it. Trying too many things. These downloads are apparently the only ones that the nook's reader will remember you are reading to resume.
I am now using Root Explorer to look over the folder structure.
In folder \data\books, there is 11GB avail. I am not sure how to find any files moved there for reading however.
In folder \data\media\B&N downloads, there is 11GB avail. I am not sure how to find any files moved there for reading however.
In folder \media\... there is 1GB available. You can move files to \media\My Files and store them here. You can see these from the B&N Library if the My Files folder is used. This works from the reader.
But I have not found how to repeatedly use the 11GB space, yet. Will keep you posted. If anyone else figures it out, please post here.
Okay thanks. I am going to look into to it right now.
i had that same problem try this, Un-root, factory reset after first boot do not setup, do the factory reset again. then re-root. shut all the way off wait a few then reboot, should work
If your Micro SD card is showing less than the actual amount of memory e.g., my 32GB showed 116MB, hook the BN to your PC. When it shows in the explorer and SD Formatter on the PC, then use SD Formatter to check the size and verify the drive letter. If there is a large unallocated space on the SD Card, it needs to be re-formatted so the boot area is the whole disk.
After formatting, SD Formatter should show the whole size. Unplug it, and the nook should say it has detected a SD Card which needs formatting. Let the nook format the SD Card. The nook will see the SD card but any apps will say the card is not mounted.
So power down the nook and power backup. Then it will mount the card and it is fully useable. (At least this worked for me.)
It should not be necessary to factory reset the nook. However, this will loose any data, documents, music etc on the SD Card. So make sure you move them to the PC before reformatting the SD Card.

As far I can tell from googling, there is no way to access the 12GB B&N partition. I have see suggestions that a android partition manager can convert the 16GB from its present 1GB and 12GB to something like 5GB and 8GB so that you can put your stuff in the 5GB partition.
Notice that 1+12=13GB. So there is 3GB not showing, and does not show in Root Explorer either. It is probably a closed OS partition which would explain why it does not show up.
I just got my nook & had several issues getting it rooted finally 2nite I got it to load all the way & Now it is telling me I have no SD card to finish off loading Titanium Any ideas would be great! Happy new year to all
Also forgot 2 say I had tried 4 different sd cards. From 2GB - 32GB. All were empty, 2 were formatted. All 4 show up as being there even I can open them on the book. I am confused

[Q] SD Card Not Writeable?

It seems that my SD card is not writable when inserted. Is this true? I tried to create a new folder on it with root explorer (I am not rooted though) and it said that my device needs to be rooted in order to accomplish that task.
Any ideas?

Did you try something like es file explorer? I would try that.
That didn't work either. It says "operation failed".
I actually noticed that it wasn't working playing act raiser and it wasn't saving my position. Moving the ROM to internal storage worked. I then tried to create a folder.

Huh. Just tried a different SD card and that one worked. Weird.

I spoke too soon. After removing the sdcard that worked and putting it back in, it no longer is writeable.
Sent from my Nexus 7 using Tapatalk 2
It works again if I pull the card out, restart the shield and put the card back in. Perhaps something up with the mounting process?
It appears that once a card is mounted, if it is removed and re-inserted, it remounts as read only.

It looks like sdcard mounting is messed up. I can't get any of the sdcards i have tried to mount.
Did you go into settings and actually click unmount before removing the SD Card? Many linux systems (android is linux) will mount devices which werent safely removed in read only mode for some bizarre reason.
I tried that as well. It still doesn't work.

when you go to storage under settings, under sd card does it show total space for card. if not maybe you have to format it to NTFS first. thats what I had to do with my new card. also said to do so on shield guide

Yes, I formatted it to NTFS before I inserted it. It shows the total space and space available, it just doesn't allow anything to be written to it. I can take it out and put it in a PC and it works correctly. I also have another SD card that I tried and it worked for a few minutes, but I haven't been able to get it to keep working.

sorry I dont know what else to tell you, i first had the same problem like yall when I stuck in a brand new card. nothing I downloaded would go on to card. and it didnt show the amount of space left under the storage menu.

The only memory card I have gotten working (about 1 minute ago) is 512MB and formatted fat32
The card i want to us is a 16gb microsdhc formatted fat32 when this memory card is in my shield it knows it has a memory card but says it has no partitions on it.
I am running testdisk on the sd card and it found 9 partitoins. I will try and clean that up.
To be honest, I've never tried SD card support on the device. So I can't say one way or another. But I'll be looking at it soon enough since I got my first build of CWM for SHIELD waiting for me to debug in the other room once the kids go to bed.
I just tried two different 8GB class 10 transcend cards, an 8GB class 2 generic card and a 256mb sandisk card. I put each card in and copied a file from internal storage to it. Then I removed each of the cards without unmounting and put them back in and proceeded to copy a file to the card again. Every time it worked successfully. I do not even know what format they are in and didn't format them before testing. And, maybe the issue didn't show up because I didn't give it enough time. I am not sure.
Also, I know this is probably a really dumb question but the micro sd slot is spring loaded. You are pushing it in until you hear a good solid click right?
issues
Having issues of my own.
Bought a 64gb sandisk SDXC card for shield. It worked 100% fine in my SGS3 formated for exFat. But not in the shield...
It seems to work somewhat when formated for NTFS. But the file path is really messed up and 1/2 my apps cant see the SD card because of this. It something like (root/storage/sdcard1/....)
2 apps that are basically usless right now due to this are Power amp & FPse.
Android doesn't normally support either exFat or NTFS. The shield may include support for them but if I had a shield I would steer clear anyway and go with what android definitely trusts in FAT32.
Hopefully NVidia will do a firmware update to sort these problems though

8gb internal storage solutions

So I got the Moto G 1gb, 8 gigs of internal storage version.
I love this phone so far and I've pretty much set it up how I'd like it, but the 8gb internal storage has turned into an issue.
I got Appmanager III, moved pretty much everything to my 32 gig external, but I still have only like 600 mb to spare on the internal, with well over half of the external left over.
Is there another app that will allow me to move all the app data left over in the internal over to the external?
If that's not enough, I'd also be interested in knowing if there's any way I can force the system to use the external as the main storage for all the OS functions. I already used adb to set all the default downloads to the external.
Finally, I'd like to know if custom ROMs like cyanogenmod would use up less storage than the stock OS, or at least let me use more of my internal by reducing the amount of bloatware (why can i NOT get rid of google movies or google+??? come ON)
I'm rooted and have installed twrp so both root and custom recovery solutions are welcome. Thanks for your time and help!
If it were me, I'd make a Nandroid with TWRP on the external as well as a backup with Titanium and then use Titanium to delete unwanted bloatware. Wouldn't that help?

System apps, ie those that come with the phone such as google movies, live in the system partition. If they are updated then the update lives in the internal storage. Uninstalling via titanium will of course free up both system and internal storage space.
However just disabling them will be sufficient, this will remove all updates from internal storage and just leave the apk in the system partition. Its the internal storage that you want to be less full as this is where user apps, pictures etc all reside (assuming you haven't yet moved them to an SD card).
Disabling is less drastic than uninstalling and is maybe the preferred option in case you otherwise uninstall something that breaks your phone.
I've tried that, but for whatever reason if I disable, say, google play movie or whatever, my phone eventually ends up redownloading them? It's really odd and honestly pretty annoying.
I'd still like to know if there's any way to keep all the main app data on the external or something though. Are Cyanogenmod ROMs installers smaller? I don't need THAT much more space to feel comfortable, having 1 gigabyte would be ok with me. I just don't like having like 600 MB free at most...
EDIT: If I can just move the app data for a few games and Google Chrome, that should fix it, too. Those seem to be the real space hogs, so if I can move those I should be able to handle everything else
EDIT EDIT: Would an app like Link2SD work for this phone or has no one tested that yet?
Hi Tazzypilar, Yes Link2Sd wil work wery well. All wat you have to do is to install MiniTool Partition Wizzard Professional on your PC, then put your micro SD card in the cardreader on your desktop or laptop to make two partitions on your SdMicro card (card must be class 10). Start program MiniTool Partition Wizzard Professional and look for your microSD card on the list with disks. Right click on your removable disk (micro sd card) and you can resize your first Fat32 partition and make it smaller for at least 2 GB. After that you will have 2 GB unused space behind this Fat32 partition. Now click with right mouse on this unused space and choose „Create“ new partition and make it ext4 file system partition. You will be prompt „Are you sure that you want to make ext4 partiton because Windows can't see it ?“ and answare „Yes“ . So, one partition will be Fat32 and you can make it as big as you like depending on the size of your MicroSd card and second should be at least 2GB (or greater - also may be smaller, it's up to you) ext4 partition and there you will move your apps from the internal phone memory.
That's all, after that you have to install Link2Sd from playstore and link apps you like to move to your SdCard. Succes ! If you have more questions jut ask !
Greetz !

Where did my storage go?
Just asked my self a very similar questions
I attachment a screen shot
From the 8gb 3,5 go to Android system
So 4,5gb for internal I thought., but no.
I installed about 2gb of apps and 200mb cache.
Ah I forgot to mention that this is a fresh install after factory reset and still I am missing alot of storage see screen shot
Is this normal? I am on stock not rooted with some apps already moved to SD Any ideas?

I am glad you brought this up, guess what I am already on M and using the SD card feature, unfortunately I can only a small portion of the apps move to the SD card the rest stays internal
Look for posts on link2sd, it needs to be a fast card and then formatted using both std FAT and ext (linux) partitions. Then you can move almost everything.

Though Im using LG H502F. Correct me if Im wrong but I think thats because the internal storage is emulated. Ive been using Link2SD and it works well. I can link app data and external data to the mounted partition. The only difference I noticed was... When opening the app it takes a couple of second or more compared to the unlinked apps... Anyways. Try to check if your storage is emulated. If it is, then that 3GB available space for a stock rom is as good as it gets. Mine have 8GB rom but the end user is only 3GB something.

In android M you can "transform" your sd card in internal memory (in Settings>Storage>SdCard>Definitions). If you have a fast 32 Gb card, you can format it to internal and it is as you have 32 Gb internal memory, but your sdcard must "live" with your phone (can't be used as sdcard in other device).
I think that is what @sandipkc7 means.

Tried internal storage option in marshmallow and at first i taught it was rubbish, but i kinda left sdcard alone and install another ROM.
So stuff on my internal storage was nowhere to be found. I installed latest recovery (TWRP) Flashed another rom and this is where things started to get interesting.
When i first converted sdcard to use as internal storage my phone was still eating up the internal memory 8GB on the phone.
Now however android system decided to do away with internal 8GB memory and use sdcard as a main storage. my photos are stored there and all data i noticed that almost everything is installed on sdcard now. so my storage is not vanishing away. I have about 1.7GB used on there.
There are some apps that can be moved manually to sdcard storage (converted to internal) - for example some of the system apps and most of google apps stay in phones memory not on sdcard and they can't be moved manually.
So my advise is covert your card to internal memory and then do factory reset or install another ROM.
Option 2 as mentioned above in posts is to use app called Link2SD - it is worth to opt for paid version which gives you more options of what to copy to 2nd partiton of your sdcard.
i have amazon fire 7 (£50 tablet) setup with option 2 - same storage 8GB. It works well. due to lack of marshmallow for this device i cannot use internal sd as an option. I have 2GB used there and rest sits on sdcard. i have installed few resource (storage) hugging apps - 1.2 GB, 2 GB each (gameloft games) - all moved to sd with link2sd app.
on my moto g 2015 i use android build in solution and it works well. You have to keep in mind that with this solution you can't simply copy files to your computer. Sdcard is encrypted at device level and it can only be access via your phone. However you can use any wifi file transfer app to copy some files over or via phones hotspot (i use droid over wifi or web pc suite to name few).
hope this helped a little

Because of this slow down i did a reset to default settings. This did help and now the phone works much better, just make sure you always have 500MB empty on the internal storage, anything less and tbe phone performance goes down imediatly.
All the talking about this no so vreat sdcardinteral storage feature was too much for my 32 GB samsung evo micro sd card, it died less than 6 months of service. This was already the 2nd from the evo series that hung up on me and let me to dataloss thanks to google drive all was backedup
I will now root the phone and get a custom rom, probaply cm offical
Did you ever find out how to recover that lost 2GB? I have the exact same problem and managed to maybe find the 2GB in the /data folder; however it is sys locked and I'm not ready to root a brand new phone yet.
I have 8 apps installed (not counting google/motorola pre-installed) on my Moto G3 and showing 3.72GB used of 4.53GB available internal. It then shows 1.36 GB used by apps, 1.71 MB by cache. Other 2GB is a mystery?Device storage shows only 16GB used of 37GB availabe due to SD card.

Marshmallow SD Card Issues

Hey guys,
I was hoping someone with some experience with Android M could help. After installing the OTA update and upgrading to Marshmallow, it seems that the OS makes you format microSD cards as either portable or internal storage. The issue that I'm running into is that after formatting the memory card as portable storage, the system formats it as Fat32 so I can no longer transfer large MKV files to play in Kodi. Prior to installing the 6.0 OTA, I had no issues transferring the files to my microSD card.
As a workaround, I tried using my USB OTG drive to play the videos but I can't get Kodi to recognize the drive as a source for my video files. Does anyone have any suggestions on how to get around these new memory card complications that Android 6.0 has introduced?
I would greatly appreciate some help on this as this was one of the main reasons I purchased this tablet so that I could use it as a temporary HTPC when I'm traveling. Thanks in advance!
Have you tried removing the SD CARD and formatting on a PC?
Seems that Marshmallow's not all it's cracked up to be.
Don't have marshmallow, but have you tried reformatting the SD card on your PC using exFat or NTFS instead?
I don't know if marshmallow will prompt you to reformat again when you put the card back in the Shield though...

You didn't mention what size of card, but if it is larger than 32gigs you will need to put the sd card in a computer and format as NTFS. Android doesn't support exfat, only fat32 and NTFS. Try that and let us know what happens!

Funny...running a 64GB SDCard formatted exFat right now on my original ST8 (Lollipop)...and also a 16GB SDCard formatted exFat on my old Samsung S4 (also Lollipop).

Try to restart tablet? The best is using es Explorer to transfer files. Fat32 do not accepted file over 4gb. Try format back exfat

Oh, wow! Your personal experience with two different phones made by two different manufacturers running an old system that was never designed for what Marshmallow does obviously contradicts and demolishes what I said.
(/sarcasm)
ExFat support can be added to android kernels, if the manufacturer decides to do so. Samsung, a maker of sd cards ranging from 4gigs to 200+gigs, has an interest in making sure that their devices work with their cards that also work in a variety of consumer computers. ExFat support can also be added in customer kernels, should the maintainer decided to do so (in fact, many kernels that I see for modern devices that also support an external sd cards proudly show that they support ExFat).
Android AOSP, without any mods or other built in support, does not support ExFat well, if at all. It may or may not work. The fact that nVidia has written that any cards over 32gig must be formatted to NTFS tells me that they have not chosen to build in ExFat support into their devices. Should someone desire to flash a different rom or custom kernel that support ExFat, that is their business. But since the OP didn't list what size of card they used, or if they were using any mods or a different kernel, I had to go with the most basic support.

ST8 = Shield Tablet 8" (original vs. K1 model).
Point is, this goes against your open ended and incorrect "Android doesn't support exfat, only fat32 and NTFS" statement.
Supporting exFAT in Android makes sense as it's the recommended file system by the SDCard association for SDCards larger than 32GB.
NTFS is in the same boat - it's also not officially supported by all Android implementations.
Marshmallow formats SDCards to Ext4 (and encrypts) when configured as internal storage. When configured as portable both exFAT and NTFS (and Fat16/32) may all be an option - OP can try both if using the portable option.

Similar problem with lg g2 on marshmallow
Hi,
Having a related problem with kodi on my phone.
On lollipop, kodi found my 16gb Fat32 otg USB drive as a source, but won't show up now I'm on marshmallow. I can still play video through mx player, fx explorer media viewer, and os video player. I searched around storage and mount folders, but can find no access to the external drive browsing the file system unless I'm using the native file browser.
Marshmallow detects partition very different with Lollipop. on Marshmallow your device can use sdcard with 128 GB like internal
its mean sdcard needed change partition format to another type (not FAT, NTFS or exFAT) the matter here then you plug that sdcard to windows, windows wont detect your sdcard but you can see it through another program like MiniTool Partition Wizard.
The problem with marshmallow and this partition used to drop out connect with your sdcard. only one way to fix it reboot your device. also, sometime they cant turn wifi on then you just needed to reboot again to let your device working normally.
We needed to wait for a new patch.

Merged SD card (marshmallow) - contents not going to SD card!

Hey all,
Just wiped and reloaded my nVidia shield tablet and set my 128gb SanDisk SD card as internal storage. Thereafter, chose to migrate (which was like 512kb worth of data - fresh reload).
Yet now anything I download/install, is all going to the original internal storage. Well, I think the installs are going internally, but all downloads (primarily Amazon Video downloads) are going to the internal.
I've reloaded 3x since and nothing is changing. What the heck am I missing? I thought the goal here was to merge the storage systems as a single?
See screenshot of storage here: http://imgur.com/1qvQtMh
Thanks!
I'm not sure this is possible if you are using fat32 on the card, I thought the card had to be ext3 or ext4.

I used https://play.google.com/store/apps/details?id=com.a0soft.gphone.app2sd.pro&hl=en to move them - use the root function and it saves having to move them manually. It also has an option to move apps to the SD Card automatically when they get installed - not tried it yet to see if it works mind.
