SD card problems stemming from CM10? - Sprint Samsung Galaxy Note II

Ok. Here is the scenario. Was on stock rooted LCJ. SD card working perfectly there. I flash to MIUI after doing a totally clean wipe and I'm able to access the SD card via the rom and PC when I sync. I go into recovery and do a full wipe and then flash CM10 with gapps. CM10 loads up okay but i notice that i have a notification that the SD card is broken and I should try formatting it. I attempt to sync the phone to the pc via USB cable but only the internal storage will mount.
I go into recovery and confirm that TWRP can still see the contents of the SD card. Having confirmed that TWRP can see the SD card I do another full wipe and then restore my stock rooted LJC. However, after restoring LJC the SD card issue persist. The phone does an error check but it doesn't fix the issue. It recommends that I format the SD card which I don't want to do and don't know if it will work. I attempt to sync the phone to the PC with the USB cable (which has always worked) but only internal will mount. Go into recovery and the SD card's contents are still showing up.
Also, I have a Kingston Media reader which I pop the SD card into and connect to the PC. Even using this media reader the SD card is still not being seen and the PC says the card should be formatted. Basically the only damn thing that recognizes stuff on the SD card is TWRP.
Anyone have any good advice on this topic? BTW...I have a class 10 64GB sd card. As mentioned above I never ever had a problem with this thing. Have always mounted it to the PC w/o a problem and has always appeared on every rom I have ever tried until trying CM10 today.

41 views and not one person has any input? guess i'm going to have to format the card and hope that works. really sucks balls. wish i at least knew for sure what caused this problem.

had the exact same issue. I had just purchased a sandisk 64 gig the week before and when it happened I had a hard time believing it was the card that went bad. I had no luck recovering anything off of the card but did format it and it has worked fine since.

its not the card...............its the formatting of the card. it has to be formatted fat32 for it to be recognized in cm10. stock format is exFAT

I had the same issue with my SanDisk 64 GB drive. I went back to Synergy and the card is recognized in that ROM. I can't get CWM or TWRP to recognize the card though. I get an error whenever I try to access the card from recovery. It sucks that I have to put anything I want to flash on internal memory

[Q] SD Cards

I tried to format my sd cards tonight via computer format option. However my computer shut down in the middle of the process and now I can't see my sd cards anymore. I can't mount it at all. When I go into the recovery to wipe it, twrp says failed.
Does this mean it's completely dead?
solved it.
googled and found this thread http://forum.xda-developers.com/showthread.php?t=1806059 for my internal sd card
and for my external, i used a card reader, plugged to pc, and reformat it.
also checked both cards for errors.
whew. i am never gonna reformat my cards again. ever.

[Q] Ext Sd card not found

Hi,
I'm currently using Task's AOKP Rom and after performing a TWRP nandroid backup to my external sd card.. My external sd card started having problems. When I rebooted back to AOKP it showed an sd card error in the notifications asking me to reformat.
I've used this 32gb sd card for 4 months, installing various AOSP and TW JB roms with no problems at all. Yes, I wipe and flash everything correctly. This seemed to just happen randomly. I plugged my phone into my computer and it only shows my internal sd card available. When I go to mnt/extsdcard in file explorer, it shows no files.
Does anyone know a way to get my ext sd card working again? I'd like to get access to my files.
Thanks,
Tom
Update: it must just be my ext sd card... I plugged it into an adapter and it's not reading on my computer. My 8 gb version works fine but my 32 doesn't read at all. Any suggestions or is my sd card fried?

CWM + My EXT SD CARD = No Fun

Well I have a new version of CWM Mod, and apparently when you format the sd-card, it no longer formats the inner sd card but your external sd card. I was really pissed as I lost all my data I had saved, but it also managed to screw up my sd card. Neither of my computers recognize my SD Card and I have no idea how I can go about restoring it. My phone can detect the sd card but it will say its corrupt randomly. So I'm guessing CWM formatted the card in a really screwed up way. Any suggestions brahs?
I'll even try to mount the sd card on CWM but it wont be able to mount it. It's a shame to waste a 32 gig sd card like this
Have you tried to format through the phone storage? Menu/settings/storage/format

Only gives me the option to mount or unmount the SD card
How old is the SD card? This phone is know for eating up the 32 GB cards. I had one for less than 3 weeks and it did the same. I use trwp but there is a thread about cards and our misfortunes with the 32 GB.

Make sure you card is not in exfat. CWM will not read cards in exfat, I had the same problem. If it is you are going to need to format it to fat 32. Most 32gigs sd cards and higher come in exfat now. You are most likey going to have to do it on the computer also it cant be done from CWM.

Yes but my computer won't even detect the SD Card. It was fine and dandy up until yesterday when I hit format on CWM on the SD Card thinking I was formatting the internal storage (since it's labelled /sdcard) but it formatted the actual SD. Windows won't detect my Micro SD and neither will my Mac. However if I put the SD card into my phone and connect via USB, it shows up.

You pressed format /sdcard, and it formatted your extsd? That's a pretty serious bug, so thanks for the heads up. What version of CWM are you running?
Op. I did the same thing a long time ago. I have gotten into the habbit of removing the sd card when I am formatting with a custom recovery. I also back up the sd to my pc and reformat the sd when changing roms. A bit off topic but I also wipe system before flashing a new rom. So far I have avoided many of the issues mentioned day after day. Maybe I am lucky but my wierd habits have been successful so far.

Did you manage to fix the problem though? Not to be rude but I'm looking for solutions towards this specific situation, not advice on what to do next time :crying: :crying: :crying: :crying:

5.8 something. It's weird because it allows for both internal and external SD use. When you backup the first open is to save to external then its internal. First version of CWM i've ever used with such an option.
For anyone wondering about a solution, I used an android 2.3 device which actually has a format option for the SD card and now my computers recognize it again. Life is good

Micro SD cards not detected

I'm having some strange issues with my S3 and micro SD cards. I noticed any attempt to access one of the folders will force crash any app that tries.
Then I did a nandroid backup from TWRP recovery and when I rebooted the phone, it claimed that the card was empty or damaged.
So I connected the card to my computer to backup everything that was there. Windows did say it needed to be scanned for errors but it didn't find any errors. It was formatted as exFat so I could put larger than 4 GB files on it.
When I put it back in my S3 it wasn't detected at all. No error messages, it was just as if I hadn't put any card in. Under Storage settings, under mount external SD card it just says to insert a card.
What I've found since then is in order to get the S3 to recognize that there is a card I need to do a full format (either FAT32 or exFAT) on my computer. If I do a quick format, it still won't be recognized. I need to do a full format.
But then, if I unmount and connect to my computer, then eject from my computer and put it back in my S3 it isn't detected again and I have to do a full format again.
I thought maybe the card had become defective, but I'm seeing the exact same behaviour now with a different card. The first one I was using was a class 10 32 GB lexar card. The second one is a class 10 16 GB Adata card. Both do the same thing. After a full format on my computer, they are detected on the phone but after unmounting, mounting on my computer, not doing anything except ejecting it, they stop being detected by the S3.
I've even tried re-formatting the card in the phone but that doesn't change anything.
Anyone know what's going on here? Is the phone defective? I don't want to send the phone in for warranty repair except as a last resort as I suspect that would mean several weeks without a phone.
Thanks!

2 Damaged SD Cards, help fix it

Hey guys, i have an issue I need some help with. My wife's Sgs2 has a custom 4.3 now but since last month when it had ICS on it, it has been giving me a lot of issues with the micro sd card. i had a samsung 16 gb on it and all of a sudden it started saying damaged sd card, made me format it but still wouldn't work. i did usb mount to my pc via recovery as my pc wouldn't even id the card when inserted. i formatted to fat32 and tried to mount the card both on recovery and after rebooting the phone but had no luck. then i bought a generic 32 gig micro sd and put it on the phone after I flashed a 4.3 rom on it. at first everything was fine and a huge music folder and CWM backups were all on the external card but all of a sudden, the phone started giving me the same message. I formatted that card hoping the default file type for S2 would work but now it keeps saying either "damaged sd card" or "blank sd card with improper partition" or something like that. I'm at a loss as to what I did wrong and what I should do. Before formatting both the cards I tried using EaseUS recovery but that thing hung up my pc let alone fix the card. If anyone has any clue, suggestion, opinion or information on this, please do let me know. I've searched both on google and here on xda but couldn't find an exact solution or one that worked. Thanks again guys.
