Weird SD Card I was wondering if anyone wanted yo help me with it. - General Questions and Answers

So I've had this SD card for a while now (32GB Sandisk Micro SD) I use it primarily for nandroid and music but recently the Android/data on it has been causing some issues.
- Phone can't read it in Android OS
- TWRP can read it just fine until I go into the folder previously mentioned. Which will then un-mount(?) The card and I have to reboot TWRP to bread it again.
- If I insert it into my computer it will work fine but will lag when I navigate to the data folder. I also can't compress or move it.
Here's the weirdest part though, The entire data folder consists of empty folders. There's one cache file but that's it. If you guys care I can probably get an Image of the card (With personal stuff removed).

[Q] Newbie with new SD Card

Hi Guys
Well I successfully rooted and isntalled a new ROM thanks to thehelpful members on this site and the guides.
I have now purchased a 32GB Micro SD to replace the 4GB in the Desire.
My question is, how do I copy the old stuff to the new card? Just copy and paste or are there hidden files etc which will require a clone?
Will all my apps work as before after changing the card?
Hope to hear back from you soon
Fat32 or NTFS?
thanks for the feedback, will try this when I get home.
Wasnt aware of the fake cards on eBay till I bought one and eBay canceled the auction!
I have purchased this from Amazon, class 4 32Gb for £40, hope its a real one.
Thanks again
ok another stupid question.
If windoes cant see the drive, how do I get 4gb of data from my old card to my new card as I cant put them both in my phone at the same time??
So just to clarify
To install a new memory card:-
I need to install Android SDK
I also need Java SDK to run Android SDK
I then need ADB to run commands to access the android
and then something called Cyanogen?
damn windows is so eay compared to this!!!!!!!!!!!!!!
So now I have to get a new pc or partition this one to dual boot to enable me to run an OS I have never used in my life?
Is this really the only way to copy 2.5gb of files from one card to another?
1. Just do a nandroid + ext backup
2. Copy all files from SD to PC
3. Insert new card
4. Copy all files from PC to new card through recovery
5. Do a nand restore
Done.

Cheers for that, I have checked the nadroid back up docs and it says
"By fully back up, I don’t mean backing up just your address book or your emails, or your dog. I mean EVERYTHING that resides on your phone with the exception of the SD card"
So I can backup everything except my card which is what I wanted to back up in the first place?
Cant seem to find a way to back up the SD card to the PC to install a new SD card and restore from the pc
tried to create partition FAIL
tried to create partion in windows FAIL
tried to load with ROM manager get E: e signature verification failed
So am I to assume my brand new 32gb card is FUBAR?
Im a little confused on how to change SD Cards too.
My partner has a Legend with only 2gig card, will swap this for a 4gig SD Card.
Can I just exchange cards in the phone, format new card in phone and then copy all files from old card to new with my windows PC?
If the mobile creates the file system structure on the SD Card and I copy the files over to it is that fine?
Thanks

Does anyone have the definitive answer on this please?
Even with copy and paste on the new card, you copy 3.6gb to the pc and then 400mb goes back the other way, all folders are EMPTY

CM7 on nook sd card

I installed cm7 yesterday using verygreen's Size-agnostic SD Card image and CM7 installer for SD Cards. with updater. That went well and booted fine but i didn't unlock the screen right away and suddenly the nookcolor booted into the stock rom and then wrote it's normal sdcard format into the boot partition on my cm7 card. I shut down and put the card into my computer and deleted the new folders the nook added then I installed gapps by doing this:
1. Then I setup my wireless.
2. Turned nook off and pulled sdcard.
3. Connected sd card to computer.
4. Make backup of uImage and uRamdisk
5. Renamed uRecImage to uImage and uRecRamdisk to uRamdisk
6. Downloaded the latest gapps zip file and copied it to the sd card.
7. Copied the update cm zip file that I originally used from the initial install back to the sd card.
8. Ejected card, inserted card into nook and booted up.
8. Recovery popped up and started to unzip both zip files.
10. Let it finish and then booted normally.
11. Set up the market.
Now for my question. When I opened the gallery my pictures were there even though I had not loaded any, same things with my music in the music player. For some reason the CM7 sdcard is seeing these files from my nooks internal storage where these files are located. My understanding is the card does not react with the nook storage....did I do something wrong. The nook boots and operates fine without the card.
I wanted to ask this question in the """Size-agnostic SD Card image and CM7 installer for SD Cards. with updater''' thread but being new it wouldn't allow me to do so.
Never mind I got my answer
I got my answer elsewhere.
Abysmal CM7.performance from sd
What brand and model SD for CM7 to get.acceptabke performance. I created a card but download is abysmal and readers are MUCH slower than factory to the point of worthlesness.

new SD card: now error: Application not installed on your phone"

Just moved from a 8 GB to a 32GB card. And cannot use it...
First I unmounted the old SD card on the phone, and put in the new, unformatted 32GB. I then choose to format it in the phone. Its a Galaxy S GT-9003i with firmware I9003XXKPN v2.3.5
It formated fine. Then I unmounted the new card, plonked in the old card and connected the phone in USB mode to the Macbook. I also connected the newly formatted SD card via a card reader, and it promptly showed up, with the correct free space (although there was a directory on it already called LOST.DIR)
I then copied all apps from the phones 8GB SD to the 32GB card, using the laptop (drag and drop). This also went fine and without a glitch. I then shut down the phone, swapped out the SD cards and booted the phone on again. As expected, it went to do the usual Scanning USB memory. It completed. The space appears to be taken up, but all apps that are on that USB are inaccesible. Their icons grey Androids with a small SD logo in the bottom right corner.
All other apps (the ones on the phone) work fine. The SD card can be used to copy files to on the computer and to take pictures...
Phone is not rooted.
PLease help, if you have a solution to this...
Many tHanks

Have you tried rebooting your phone? If it still does not work, try to unmount your SD Card via settings and then wait for it to successfully unmount and then mount again

ah ha
So, I cannot even find the app2sd app under My Apps on the Google Play store... weird. Its also not listing under Manage Applications. Would this really be the cause of the problem!?
Anyone else have any ideas, why the phone cannot load the apps copied from the other SD card...!?!
First of all u have to move all apps from the old sd card to the phone. Or while inserting ur new sd, the apps you moved to your old sd will not work

Thanks, but I canot make sense of this. Firstly all apps on the old SD card will never fit onto the phone (8GB, vs 2GB space), and secondly elsewhere online they always talk about copying files to the new card and then inserting that instead of the old one....
mmmh...!? Whilst I apprecite your post - its not working for me
When apps are moved to the SD card, it isn't entirely moved to the SD card. Only part of it is, that's why when installing apps the space for apps still decreases. Therefore you should use titanium backup or similar backup programs to move the applications.

Thanks,I had a look at titanium backup, but it requires root access (my phone has not been rooted). I really dont think one should need to root their phone to move from a small to a larger SD card without having to re-install all apps from scratch...!?

Without root you will not be able to backup data(AFAIK)

OK, so I rooted the phone and used Titanium Backup. It created a backup file on the phone memory. I thought, voila, I am good then, popped in the new SD card, formatted it, and did the restore from Titanium Backup... but:
still getting a lot of greyed out files in the application folder and on the home screens... I really cannot believe all this work is needed to swap out SD cards from a smaller to larger capacity! what a pain in the •••

I have the same problem to, just backed up my old 16gb card to my pc, installed and formatted a new 32gb card in my S4 and copied the data back over and all the apps that are on the sd card are showing up grey.
Ok, after a quick google, i've found that making a clone of the card and then copying the clone to the new card works
you can use HDD-Raw-Copy-Tool to do this (you'll have to google it as I don't have enough posts to post external links)

Thanks! Yeah that works perfectly! (Apparently there are some "secure" folders in the SD card that start with a period, and the contents do not get copied at all. Those hold the apps and data.) However after using HDD-Raw-Copy it will create an exact replica of the smaller SD card on the larger one and the larger one will appear to be small too, so you must resize your partition or you won't gain anything, your new card will be exactly the same as the old one! You can use MiniTool Partition Wizard home edition which is free to do this: partitionwizard.com :good:
I had the same problem but I was able to fix without extra software. Took old card out of my phone and installed both externally via flash readers to my pc and copied files from one to the other. View hidden files is turned on just in case any hidden items is also copied. This work great for me all apps are accessible now. Hope this helpped
Here is the step-by-step solution: http://www.tomsguide.com/forum/id-2545604/move-data-card-samsung-galaxy.html
There are two ways described to do it successfully:
METHOD 1 uses the xcopy (or xcopy32) command in a Cmd Prompt windown on Windows. The /h switch used on the command allows the hidden and system files to be copied!
METHOD 2 uses a straight copy from old SD card to the new SD card (or from old SD card to folder on computer, then from folder on computer to new SD card) using the simple drag and drop on Windows. BUT YOU MUST HAVE WINDOWS EXPLORER CONFIGURED TO SHOW SYSTEM AND HIDDEN FILES!
Just to be clear, the solution to the problem is trivial. You are simply copying ALL the files from one SD card to another. There is absolutely no reason that copying ALL files from one SD card, including the complete file structure, to another SD card should not work. Your phone can't tell that you switched SD cards. It only knows the files and file structure it can see on the SD card and if they are EXACTLY the same as they were before the switch, your phone should work exactly like it did before the switch except now it will see more free storage space on your larger SD card (which was probably your goal in the first place) AND your phone may possibly even run faster by accessing the data much faster if your new SD card is a faster class of storage media.
YOU DO NOT NEED TO ROOT YOUR PHONE OR INSTALL ALL KINDS OF CRAZY APPS ON YOUR PHONE OR SOFTWARE ON YOUR COMPUTER TO DO THIS!!!
BUT, the key is that YOU MUST ALSO COPY ALL THE HIDDEN FILES and there are lots of them on Android! Everytime I hear of someone having a problem with switchinging to a new SD card, it is because they did NOT copy the hidden files OR their SD card was not properly formatted (FAT32) for the phone.

micro sd card - strange trouble

so i took out my memory card and put it in a new card reader, the card reader did something funny and all files & folders disappeared and there was just one 0kb file named USB&somegarbage. I put the card back in the phone and it surely created the DCIM folders again etc.
I then connected it to icare data recovery and i am able to see that all the files are still there with most of them not corrupted but the folder names are gone,I wondering if there is a way for me to recover the original file structure back? any one?
Thanks in advance.

In my opinion, I would just recover everything and just format that card. When you reinsert the card, the phone should restore default folders back and just place your data in the respective folders. I don't think there is anything you really need to add new folders for, other than the default unless you had a specific folder arrangement for photos or something like that.
Format the card to NTFS not FAT.
Do it either on your PC or Mac.
But you must install a NTFS app on the android, otherwise the device will not recognise the card.
You can format the card to NTFS using the app too.
The app will auto mount the card when the device is turned on.
I've found this method more stable than having the card in FAT mode.
I'm surprised Samsung haven't sorted this out yet!

How to prevent Android 11 from using the SD card?

Dear all,
the following problem might be unusual and the opposite of what other people want, but as the title says:
Is it possible to prevent Android 11 (and custom ROMs based on it) from writing to the external SD card? That is, I don't want apps or the O/S itself to store any data there. You now probably are asking yourself whether I have gone totally crazy, putting an external SD card into the phone and not wanting it to be used, so I'll give a bit of background:
I have a Samsung S9 plus Duos (G965F/DS) and have installed a custom recovery (TWRP 3.5.2) and a custom ROM (ArrowOS 11) onto it. Then I have installed SSHelper 13.2 and have put an external SD card into the phone.
I am taking backups very seriously. I don't want to root my phone, but nevertheless want bit-for-bit backups of all partitions or data, respectively. I don't have much data on the phone, but the data and the O/S configuration I *do* have must be regularly backed up no matter what. The backup must *not* be in the cloud. That led me to the following idea for the backup process:
- Boot into TWRP
- Let TWRP make the backup, using the partitions of the internal storage as source, and using the external SD card as destination
- Reboot to system
- Fire up SSHelper
- Copy the backup from the external SD card to a PC, e.g. via WinSCP.
That process works like a charm; I have done it several times.
[ Side note: The SSHelper / WinSCP combo is ingenious. It enables me to transfer data (e.g. backups) between my PC and my phone without involving the cloud and without having to pull out the external SD card all the time. Doing the latter every other day would probably damage the phone or the external SD card quite fast. ]
Now I have only one small problem left: Android itself of course recognizes the external SD card as well and installs a folder structure on it (e.g. Downloads, Movies, Pictures etc.). Although I actually haven't seen files (other than placeholders) in there yet, I have no clue if and under which circumstances apps or the O/S might put important data in these external SD card folders. I have to prevent the latter, because it would render my backup method (backup internal storage completely to external SD card) useless.
Hence the question: Is there a method to tell the O/S and all apps that they may read the external SD card, but under no circumstances must place data there?
Thank you very much in advance for any ideas!
P.S. I have seen many threads where users had problems with the external SD card, e.g. not being able to make apps use it or not being able to see its contents. But I somehow have the opposite problem: Of course, I need to see the external SD card's contents (which is no problem), but I want to prevent normal apps and the O/S from writing something there.
No you can't prevent android from creating default folders on it, but I'm pretty sure you can exclude them from backup.
Thank you very much!
However, excluding these folders from backup wouldn't be wise if Android or an app would have put data in them ...

Then don't exclude the whole Android folder, just some folders inside. Like /obb folder or system apps data inside /data
Or just exclude "LOST" or other cache folders.

Assuming you are speaking of an External SD-card ( Note: As with Android internal storage memory by default is named SD-card ).
As long as you don't use an external SD-card ( completely or partially ) as Adoptable Storage by default neither apps nor OS itself write to it ( store data on it ).
@jwoegerbauer Thank you very much! This what I have experienced, too. I have seen the folders, but no data in them. I am still wondering why it creates those folders at all if it doesn't put data in them.
I eventually have missed it, but I think I have gone through every option of ArrowOS, but didn't find a menu item where I could activate (or inactivate) the external SD card as adoptable storage. Therefore I suspected it would do that automatically, depending on circumstances.
Another mystery (for me) is that (AFAIK) data would go into subfolders of the "Android" folder on the external SD card. But the Android folder is nearly empty, while the rest of the folder structure (Documents, Pictures etc.) is at the root level of the external SD card (i.e. at the same level as the "Android" folder).
P.S. Yes, I was speaking of the external SD card. I'll check if it's still possible to edit my posts and make that clear.
Thank you very much again!

I should have made myself more clear: My plan is to have all data only in internal storage and to back up internal storage to the external SD card.
When there is normal data (besides these backups) on the external SD card, three problems arise:
1) The normal data on the external SD card takes up space. If I can't control which data Android and the apps put there, the remaining space may not be sufficient for the backups one day.
Every portion of normal data which is on the external SD card counts twice in that sense. First, it increases the backup size by its own size; secondly, it reduces the space which remains for the backups by its own size.
2) I know that I wrote that I will transfer the backups to a PC wirelessly. However, I still want the phone to run normally even after I have removed the external SD card. If Android or the apps put normal data on the external SD card, this is not possible any more.
3) Excluding certain data on the external SD card from backup is problematic and would void the main advantage of my backup strategy:
I really don't need to think about what to exclude or include. I just back up all internal partitions, completely and bit by bit, to the external SD card. If I lose the phone, I can buy another one, flash TWRP onto it, restore those backups, and have the original O/S, apps and all data, and even dm-verify will be no issue.
I have no clue about Android and I am not able (or would be too lazy anyway) to decide which data to include or exclude to achieve the same. So I really would like to avoid that triage.
I believe that some time ago I had found an ugly trick to keep Android and the apps from creating and using those folders. I'll have to check whether I have taken notes about it ...
Thank you very much again!
@D9yHyi8Fe3mo1YgM
To clarify things:
You have to distinguish between portable storage and adoptable storage. Adoptable storage really extends device's internal storage, whereas portable storage does not.
If apps are granted WRITE_EXTERNAL_STORAGE / READ_EXTERNAL_STORAGE permission then they can access the external SD-card, too.

Thank you very much again! I suspected so, but didn't find the setting in the UI of ArrowOS yet. I am nearly sure that I just missed it, and will research again (just out of curiosity, because extending the internal storage to the external SD card is exactly the opposite of what I want).

I see. Thank you very much for the explanation. I'll go through the app permissions and check that. Then only the O/S itself could put data there.
[ Side note: In the meanwhile, I have corrected my posts according to your hint regarding the term "SD card". ]
I don't know if this topic has aged or not, have you found any solution?
I don't want Android system to write files like Android-Podcast-Alarms-Music-Notification into my sd card, I want my sd card to be clear and clean
this order system which android uses is very useless and annoying, when will they remove that??!!
