[Q] CyanogenMod 7 is ruining my SD cards

Now I'm not moaning about CyanogenMod here, I'm just trying to understand how I can fix the issue.
Basically, I had CyanogenMod 7 RC2 on my Desire Z. That was it.
Eventually I saw through ROM Manager that the full release of 7 was out so I downloaded, took a backup, wiped everything and did a fresh install of the new ROM.
It installed fine, but none of my apps that needed root access were getting it.
So I booted into recovery, restored my backup, root was back.
I then installed 7.0 over my RC2. That worked fine, but again root was gone.
At this point, my phone started damaging SD cards.
It suddenly started saying that my 8GB card that came with the phone was damaged. I tried to fix it on the phone, but it just said 'Checking card' and then giving up.
Putting it in an old MP3 player, it is not detected at all.
Putting it in a card reader, the card is unreadable and when I try to format it Windows says the card is 'read only' (this is not due to the reader).
I put a functional 2gb card I had lying around into my Desire Z and it broke it in the exact same way.
My question to you guys is - what could be causing this and how do I fix it because I have a 16gb card coming and I'm obviously cautious of putting it in the phone.
Also, how would I go about flashing the new Cyanogenmod 7.02 ROM if my phone keeps breaking SD cards I put into it?

This error can be because when ever you install a CyanogenMod ROM over another, It leaves files your new ROM think is useful such as data that the new ROM doesn't support. It is damaging your SD Card because it keeps attempting to fix the error but is making it worst by trying to remove system files. Your best bet is to try another ROM and see if it does the same thing and report it to CyanogenMod Developer Team if it only does this to CyanogenMod ROMs otherwise it would be just a virus on your SD Card feeding off of personal data. If it is only CyanogenMod ROMs, we will adress this issue ASAP. Hope I helped

Thank you VS4, you are indeed helpful
I've since heard some people have managed to fix their SD cards by formatting them in ClockworkMod but I can't even mount it first in order to do this! Is my card truly dead?
Also, do you think the reason that CM7.0 had no root (even when it was a clean install) was due to me not 'fixing permissions'?
Thanks

Just a note to say that I've managed to fix it!
Despite being unable to 'mount sdcard' in clockworkmod, I found I was able to activate USB Storage and through this I was able to format the card (Windows 7 was previously saying that the same card was 'read only' in a multitude of card readers).
I hope this helps any poor chap with the same problem.

I had this exact same problem, munched 2 of my 8GB cards, and had a 16 on the way. I somehow fixed it before the 16 came and I've never had the issue since, glad to see an explanation of it.

Thanks, nofixio!
I had the same problem on my Samsung Fascinate with CM7. It ate my 16GB SD card to the point where the phone wouldn't recognize it, CWM wouldn't mount it, and it wouldn't show up on my computer in multiple SD readers.
I wasn't quite clear what you were suggesting when you said you were able to "activate USB Storage." I thought maybe you meant within CWM. That didn't work for me, but I was able to boot the phone up with the problem SD card in it and turn on USB storage as normal. Suddenly my computer could not only see the SD card, it could see all the files that were on it before it died! I backed everything up, formatted the card in Windows, and everything's good now. Thanks for the tip!

I'm not sure why you would ask this in such an old thread but... Try just plugging it in to your computer maybe? What ROM are you on?

im running cm7 ... it wont read from computer. i tried several micro sd card readers. it just tells me it cant format. its just like what was mentioned before.

Weird, I've never had any problems with Cyanogen 7 roms. I've flashed one over another and had no issues at all, Mayb because I use SuperWipe before hand? Or maybe its a certain sd card issue???

Running Desire Z and Andromadus Beta 11 I had similar problem after I had applied remote wipe from Exchange (wanted to see if it works). Remote wipe worked: it destroyed contents of SD card and erased phone back to factory settings. After wipe mounting SD card failed and Andromadus seemed to be unable to format the card.
Solution: Booted phone to Clockwork recovery and applied advanced -> Partition SD Card.
Posted this on this thread since it came first when searching solution.

Go into Recovery (Clockwork), go to mounts and storage, then scroll down and it should say mount USB storage.

Internal memory folders changed after J.B Kies update?

Hi I have been dealing with this problem for awhile now and still haven't been able to find a fix (without rooting). After I updated JB from Kies when it came out my internal and memory card folders are completely different? Also it says I only have 11.95GB total in my internal memory. The internal memory folder says :sdcard0. And my memory card folder is: extSdCard? I'm not rooted. Does anyone know how to get the folders back to the regular names ext sd ect? Any help would be appreciated, thanks.

That is how it they are formatted now. It's not a mistake or anything being messed up. I guess I'm just used the internal being sdcard0 and ex sd card being extsdcard. I don't use myfiles much. I use root explorer and it can displays it as storage and then inside that folder is extsdcard and sdcard. Or there is a fodler just called sdcard for the internal in the root of the file system.
What problem is it creating, other than just being different than you are used to ?

Yhea, i'm having some trouble too. After the update my extCard is totally mess-up. The folders with the pictures and songs are not recognized, and the Gallery doesn't show hundreds of pictures, but i see if i use a file manager. I've synced all my songs so far, but with the pictures is a mess: seems also the format is not recognized anymore and with Kies i'm not seeing a way for put the pictures in the new folder named "Photo". It's really frustrating.

I cannot use the Apps2sd app anymore. And basically I would just like to be like before the update.

i'll try not to rant too hard but Kies and OTA firmware updates are a joke. you are essentially dirty flashing one rom over another with no real clearing of caches, no resetting, no way for all the programs to regroup, rebuild and run on the system hardware/software properly. the thing about dirty flashing is, it sticks well with some devices but generally not with many others. you'll see these types of issues many times among the avid flashers and those that must have the latest release of a developers rom.
i would recommend backing everything up, booting into stock recovery, wiping data/factory reset and wiping cache. if you decide to perform another update via kies in the future, i would do this procedure before AND after the update.
yes, you have to start over when you perform these sorts of actions but you have to ask yourself, are you happy with how your device is performing now (before the update)? is it worth starting over? (it might be if you're going to run on the updated OS for a year or so) and how well do you want it to perform after you install the update?
cheers
EDIT: i just assume everyone accesses recovery and download mode so i didnt post the button combo. recovery is: Volume Up + Home + Power. release just the power button when you get a vibrate.

This is normal for a 16GB SGS3. 16GB is advertised but actual formatted available space is less. 11.95GB is right on par. This is the case for just about all devices that have memory that is writable, including hard drives on a computer.

Any particular reason why you are using Apps2sd? $10 to $20 will land you an external memory card with huge amounts of space (32GB at least). This is plenty to store music, photos, and other misc. files. And even with a ton of apps installed to internal, you still should have ample space left over. There is just no good reason to use Apps2sd on this phone as it has so much internal memory. If this is just to keep you from losing data, then I would suggest rooting and using an app such as Titanium Backup as it makes it super easy to restore apps and the corresponding data after anything that requires a factory reset.

As stated by xBeerDroidx, factory reset from stock recovery. You will have to re-setup your device but it will be a one time frustration for now until the next update.

Actually i did.
After the update, without factory reset, everything was (almost) fine… except a strange malfunction of the Gps (lock signal lost after a while) and sporadic reboot without reason. For the Gps I’ve found here the solution (NV Rebuild), but for the reboot… I wasn’t sure about it. So I decided for a factory reset. After that my ext card, with the ICS paths, was not recognized. So bucked up everything, format the ext card and let Kies sync my files and create all the folders needed from JB: Camera Photo Video for pictures, and media for the music. Now I’m let’s say 90% ready to go… I’m curios to test especially the Gps.

[Q] internel sd card unmounted yet apps work fine

So been trying to work out this issue for past couple of days now. Galaxy W (obviously) PACman rom.
Updated to the latest version of rom, all fine but didn't go pristine. Eventually had some issues, biggest of which being I couldn't access internal SD card as storage, yet all my apps were working fine. So, tried again, went pristine, all fine for about a day, no issues whatsoever .... until dreaded internal sd unmounted. Tried again, pristine, double formatting everything and double clearing cache etc. No problems. Updated kernel to skull kernal to fix the bluetooth. No problems.
And now again, it's happened. I've tried to keep a mental correlation in what I'm doing to hopefully give me an idea of what's going on but not having much luck; hoping someone here knows what this issue is as it's driving me mad
I've changed my name in Google; could it be some sort of permissions thing?
USB; phone set to Media player, it might be it's happening after I've transferred but since everything is working fine, it's hard to tell
I've not restored anything, gone completly pristine (took hours) in an attempt to retrace my steps and not get this issue again. Part of me thinks I may as well just leave it as everything works, I can even install fine. But I can't browse it via any file manager or via USB, and a couple of programs I use (CoPilot for one) won't start properly because there is no SD card mounted.
Things I've tried -
CWM, fix permissions
Reboot
Checked Storage under settings, I can see how much free space there is etc.
Enabled and Disabled USB Debugging and tried to see it on my PC (nothing, external shows up fine)
Anything else anyone can think of before I wipe the lot and try again for a 4th time?

*sigh*
No idea why it's doing it, but yeah, seems to be the USB transfer. Problem solved.
So changed USB from Media Player to MTP and back again while connected to PC, internal storage now available.
Always the way, struggled with it for a few days, finally decide to post for help, and I solve it in less than 10 minutes of making the post :silly:
Knowing my luck, it's a known bug I've somehow glossed over in all information!
Edit - spoke too soon
After a reboot, same again. Everything "works", I can install and uninstall, but I can't browse the internal sdcard0 with a file manager or via PC. The above trick isn't working now.

Just thought I'd give it one last bump. Situation is that after every reboot, my internal sdcard is not mounted. I have to connect the phone to a PC via USB, then disconnect and hope that the phone mounts both sdcards. Usually works first time but sometimes I have to connect - disconnect 2-3 times before the internal card is mounted.
Anyone happen to know how to mount the internal card via command line? I could then workaround it with a script via smanager.

help with SD/internal mem!!

So I don't know what I did but I went to my recovery (TWRP) and accidently did something I do not know what, but now I can not view my pics, files, music from both SD/internal..but when I reboot my phone and check on the computer I see everything there and my storage says it's full. I just can't see it on the phone

I think it would be very useful if you can provide a lot more details and specifics about your situation like
which rom are you using, did it ever work properly if so what was the last thing you have done with the
phone before you started having this issue.
If I were you since you can see your internal and external sdcards on your computer I would first create
two new folders on the computer's desktop, one for internal sd and the other external sd.
Then copy all the files and folders from your internal/external sdcard to the appropriate folders on your desktop.
After doing that check how much space is being used in each of your two new folders on your computer's desktop.
See if there are any really large files which look suspicious to you.
After doing that and if the sdcards are either really full or not really full you will have a better idea of what to do to
trouble shoot the issue you are having with the phone.
It's always a good idea in any case to have a backup of both internal and external sdcards on your computer.
Good luck!

It isn't an ROM issue, but I was on PAC Rom. My problem is I did something in the recovery by mistake and pressed something maybe that formatted my memory?? :crying:
edit: Issue seems to be fixed..

That's one of the reasons I was suggesting that you copy everything from both internal and external
cards to folders on your computers desktop.
So you could see what you really have. If you get a message saying sdcard full or anything like that
it normally would mean that the sdcard has not been formatted, if it was it would be empty and it would
not give an error message saying that it's full.

Sometimes the PC will see the files after its been wiped by the phone. Copy everything to desktop, hope it actually copies everything, format sd card using Android OS, copy everything back, get a Dropbox account.

Find a root file manager.
Go to
Data/media.
That's your internal sd card. Some roms create a virtual sd card (sdcard0 or emulated sdcard0), which is android making a a fake one. All your pictures are still on your phone.
Just copy data/media into the virtual sd card an reboot. Your stuff shall appear again. If you have issues just pm me.

MicroSD card help

Hi everyone,
I have a 64gb sandisk microsd external card, in a att galaxy s3 and it appears to be acting very strange.
i can't add or delete anything from it, i put it in my brothers galaxy s2 to format it (my s3 not having the option(which is strange)) and it let me format it, but when it remounts its at the exact same place, with 42.2gb free storage space, which is what it was at before i formatted it, i did it a few times same thing.
if i manually try to delete things from the card through my phone or computer they either hang or they do delete then upon reboot all the files are back. I hope its not corrupted but it sounds like it is. i've used a few apps like sd tools which runs speed tests, and i get about 130mb write speed a second and 5000mb read speed a second which sounds like it should be able to read and write things but unfortunately it just won't
any help would be greatly appreciated.

Hmm. You might have to try a double format in TWRP, then when you load up the System use the system's format tool. (i.e. Storage --> Wipe SD Card). If that doesn't work, you might need to find someone with a microsd to USB jig or something of the sort and use a computer to format it.

yeah thanks for the support, tried a number of things in twrp but to no avail. i went out and bought another 64gb microsd card and put it in my phone, works perfectly. but still i'm trying to get the other card working. the new card came with an adapter so i've been trying to format it in my computer. i've used windows format, i do the long one, it gets all the way to the end looks like its complete then says unable to format. and all teh data is still there, i've also tried guiformat by ridgecrop, says success but still all the information is still there.
i don't know if this means the card is corrupt i'd always assumed i'd get corruption error messages.
is there a program i can use to scan the card for errors or corruption?
thanks again dude for the responses any additional help will be very much appreciated still.
again thanks.
