[Q] CM10 MicroSD Format? - Verizon Samsung Galaxy S III

Hopefully I can explain this well enough. I installed CM 10.1 through cmupdater. Before I read the forum saying do NOT do this. Well I have used odin and gotten back to stock, and also now have rooted, and reinstalled CM10. My only problem now is my ext SD is always giving me errors. It does work properly some of the time, but I know it should not be doing this. I have read in a couple places that I should try reformatting the SD, but when go to the settings menu and storage there is not an option to format. Any ideas?

Plug it into the computer and format it to Fat32. If it's 64gb then you need to download a third party program to reformat it to Fat32.
This is semi-related, if you're on JB 4.2 then make sure you have a JB 4.2 compatible recovery. Either CWM 6.0.1.9 or TWRP 2.3.2.3

So I thought I'd give this a try. Went and bought a card reader, and it won't recognize my sd on Mac or Windows PC. I tried my wifes SD just to see if the reader wasn't working properly, and it recognizes hers right away. Is it possible the card could've gotten fried somehow or is there something else I could try?

The sdcard very well could be on its last leg. If you can't get it recognized in a computer to reformat or even copy the content over, then there's nothing else you can physically do. Your best bet would be to either get a warranty replacement or purchase a new one.

I could really use a hand with this pickle

okay, so i've found myself in a bit of a pickle. Recently I've been running the CM7 nightly's, but today I tried out the RoyalGinger rom and I believe it either corrupted my SD card or it's blocking my SD card from being used/read.
Tried several times to reformat it but each time it said 'checking SD card', but the weird thing is I have an active wireless connection, but I'm not getting texts. I can download from market, get on Facebook, etc, but my texts won't come in until I reboot the phone. A few times I booted it up and it wouldn't allow me to even see my homescreen because it'd pop up with EVERY app force closing (including google services, framework, etc), I was able to get back to my homescreen by clearing by Dalvik Cache luckily, however I'm still unable to do most anything. I went in to wipe/restore but it says cannot find SD card, directory invalid, cannot mount, etc.
Is there a way to reformat my SD card through terminal? If so could I get the code procedure for it? or anyone have any ideas other than picking up a new micro (which isn't a big deal but I'm strapped on money til Friday) but i'd still prefer to know that it's JUST my SD card and not my phone memory. Anyone? Anyone? Beuler? Beuler? Thanks in advance. I'm really sorry if I posted this in the wrong section, but c'mon, everyone gets one.
Ok so do u have a stock backup rom? Ide say go to rom manager and go to recovery and whipe etc.. Then install that stock back on it.....And can ur sd card even read at all? Just get any.file manager and check your sd.

I think I have a backup rom of CM6, but not an actual android stock rom. It won't allow me because it says 'must have an SD card inserted' then it says must have clockwork mod recovery installed, which I do, the current version. Now that it says that I'm afraid to boot my phone into recovery, and I can't really tell if my SD card will read. I was able to use my file manager and the entire SD folder is blank.
ten minutes later: still boots into recovery, none of my backups are available on it. I was thinking about downloading a rom from the phone and trying that way, but I don't know if it'd save to the (apparently unreadable) SD card.
Ok try this...... Find out what recovery you use 3.0.0.5 or the normal 2.5.1.4 for froyo then download a rom thats the same recovery as the one u have on it right now...... If its the same as your cyanogenmod 6 then install that from the recovery manually!!!
if its not then download a rom that is and make sure you use a file manager to see if the download sticks in your sdcard. And if it doesnt stick then......your problem sir might be a corrupted sdcard, or a phone that cant read your sd.
Hope its not either or, so give it a shot.....
And ur supposed to have a stock backup as soon as you root and switch roms man Lol makes life easier

It sounds like he doesn't have access to his sdcard. It doesn't matter how many backups you make if that's the case...
If you happen to have a sdcard reader or a microsd usb adapter you could format it in windows, copy the files you need, and start again. Also did you try connecting to your pc and seeing if it's readable that way? You can format the card if your pc recognizes it. If you have adb set up you can push the recovery image to the phone without a sdcard. But once again without a working sdcard you won't be able to flash a new rom.
Hey guys I'm pretty sure it's just my SD card. I tried saving an image, just to test it and it says 'an SD card is required to download images.bin', so I'm HOPING it's just my SD Card, however my notifications are working properly so I can at least deal with it til friday, if it IS my SD card reader in the phone, well... I have a plan for that, however due to already technically breaking that I shouldn't go into it. Thanks to you guys for taking the time to post and if you know anything else that might help me I'd gladly accept it.

Hi, I have a reader on my laptop but not the adapter, so I can't tell and yes, you were right, I can't see any of my backups (which I have my stock, then cm6 and cm7) so I either need to find an adapter or get a new SD card. luckily I pulled all of my camera images off my phone last night when I put the new rom .zip on the phone sd, so I'm not really worried about 'losing' anything as long as I get my phone working back in proper condition.
Well that happened to me before as well.. All i did was replace sd cards lets the phone do its thing flash a different rom like CM6 or CM7 and then once replaced i got the adapter for my old sd card reformatted through windows and put it right back in and it worked.. So try that?
Ill have to. Thanks a lot guys I do appreciate any comments and suggestions and ill be picking up a new sd later thia week to fix it but can amyone recommend a good brand sd to pick up? the apparently failed one was a samsung 8gb

Hp is very good, u probably can find one with 8 gb. At best buy.. But if u want a 32 gb then thats online all day

I usually use sandisk so yeah try that?
Something similar happened to me. Your SD card likely has a bad or corrupted file. I used Win7 to copy over what I could to a folder in my PC. The Win7 automatically refused to copy over the corrupted files while carrying over everything else. In XP, your file transfer stops and you have to try again to ensure you have everything that's not corrupted transferred over.
After copying, I just went ahead and formatted the SD to FAT32, transferred everything back, installed on my phone, and voila.
Go into recovery and partition the card. You'll lose everything on it but it should be useable after that

CWM ExtSDcard support?

Is there any way on the gs3 to save your nandroids to the ext SD card?
Mine shows the option greyed out.

If you booted into CWM using the EZ Recovery app then you would notice that you can manually save backups to either sd card.

It might also be that you don't have your external card formatted to fat32. CWM doesn't like the exFat format that I believe all big cards come in.

If your talking about rom manager then yea thats normal!
On a side note, I recomend flashing files manually in CWM recovery...you would not believe how many threads I have helped folks get out of a softbrick or bootloop situation by flashing with rom manager. The app works great, but you still need to know the background information on what your flashing! To many people think since they can pull the file up on RM, it must be compatible, or they flash with the wrong recovery = soft brick! Part of the main reason my guide is written in its fashion...provides proper instructions to flash, makes one read a bit, and repeats its self to pound the info into ones head. Not tryin to preach to ya, just wanted to share some possibly useful info to yourself and others. thx
I was wondering the same about saving to external from rom manager. So our only option it looks like is to boot to recovery and manually go to save it to the external sd?

[HELP] Cannot move files into EXT SD

Ok well i've tried for hours now.. using Astro.. ES explorer and even the native my files application and i cant seem to move pictures from my phones storage to my EXT SD card... and something else i noticed.. is when i adjust my cameras settings to save to my external SD card it gives me an error as well but i can still read files off of it.. so whats wrong?
i'm running Clean rom 5.0
it worked before on Stock and Liquid smooth RC7 and RC8
no one? come on...
All I can say is try a clean install see if that fixes it, probably not that helpful but worth a shot.
You may want to backup everything to a computer in case this sd card fails on you. You should reformat the sd card (to Fat32) and see if this resolves your issue.

Make sure your sd card is formatted to Fat32. You'll lose the ability to transfer >4gb files.

Thanks i kinda figured that was the issue that it doesnt support exflat. how would i go about installing team win recovery if i have clockworkmod installed same way with odin? i know team win supports exflat
Another question that pop in my mind would i be able to back up my rom on a differnt sd card with clockwork.

Just download "GooManager" from the Play Store. Press your menu button and select "Install Open Recovery Script" and the latest TWRP will install.
In regards to CWM and two sd cards. Sure can, but who really uses two external sd cards for one phone?

[Q] external memory card problem

My ext. Card (32gb sandisk ultra micro SD) constantly corrupts random files. I don't think it is the card because this is the third card I've used with the same results. I can however use the card on my laptop and it works perfectly fine via the card adapter. If I put music or movies on the card from the laptop and try to use it on my phone the file won't work or works for a few seconds then stops. Also, when I save to my phones internal memory it works fine. Has anyone else had issue? I've tried factory resets and custom ROMs but its always the same result. ANY input would be greatly appreciated.
Don't install custom ROMs on top of each other.

Tried it and it didnt help. I tried putting some files on my phones ext sdcard via usb cable from my laptop but it freezes in mid transfer. Also when I tried to make a Backup with CWM it wouldnt complete. So i wiped/formatted and fresh installed stock rom again and installed TWRP with the same results. I think its time to just give up. Also when I try and install SUPER USER it gets stuck in a boot loop. Frustrating.
ideas anyone
Okay I was able to flash cm10.1.2 and super user with twrp. Its crazy I can transfer media to the internal storage just fine but not to the SD card. I've factory reset with twrp and reinstalled stock and nothing seems to fix this.

I'm so glad someone has posted this issue, I can confirm it does exist on stock Rogers RUXUMA ROM with an external Sandisk 64GB class 10 card.
The problem especially occurs when downloading compressed files from the internet. They appear fine but when you try to extract them, they have CRC failures. Sometimes they are fine until you reboot the phone.
I have been trying to troubleshoot this issue for months, its a problem with MTP or exFat on this particular phone. I've tried both CWM and TWRP, no success. The old Gingerbread ROM which didn't have MTP or exFAT support works fine, I've gone back and tried dozens of times.
I'm just surprised nobody else has reported this.
