Hi,
I have a Galaxy S3 (GT-I9300) with CynogenMod 9-20120804-NIGHTLY-i9300 installed. I am using the standard CM9 kernel etc as well.
My issue is that I have a 64GB Sandisk external SD card that I have formatted to Fat32 so I can mount it and use it with CM9. It mounts fine first up but then starts un-mounting then goes through and prepares itself and mounts again. It does this off and on at random times. Is there anyway I can check whether this is a software or hardware issue? It is extremely frustrating, can't listen to music or anything off the SD card as it keeps unmounting etc.

jus a suggestion.... if you can try the sd card in another phone or try another memory card in your phone... that way you'll know if its the software or hardware
Hey, no I don't have another SD card to try. I may be able to try my SD card in an old Nokia I have though...
I really wish it would work, want to be able to put my 20GB of music on it!

I had a similar problem with cm-9-20120728-NIGHTLY-i9300
I inserted a brand new sandisk 64GB sdxc and it reported 'damaged sd card'
when i tried to format it from the phone it got stuck at 'unmounting device'
The solution for me was putting it into my brother's galaxy s2- format took 15seconds and i could use the card normally on my phone.
Well I formatted the 64GB SD Card in my old Nokia without an issue. After putting it back in the phone I had the same issues again.
I then tried a old 8GB SD Card I had around. That also was un-mounting on and off.
It seems like the problem maybe the actual SD card slot itself. See a picture below. It seems to be worse once I put the battery cover on the phone. If I old the card hard in it doesn't seem to un-mount like it has been doing. Not to sure what to do from here.... Maybe flash stock firmware and check SD card operation. If I have the same issues then maybe send away under warranty.

Hi Guys,
I've just got a new 16GB microSDHC card. I've formatted it in the phone through android and through recovery, I've formatted it with GParted under Ubuntu and I've formatted it under Windows 7 (Quick format).
Despite all this I'm getting an I/O error from ACast whenever I try to download a podcast and the same from Google Listen.
Also when I go to look at the contents of the card in the file manager sometimes it says the card contains the correct files and folders and sometimes it says the card is empty or only has two or so folders.
What's going on? Have I got a dud card?
I'm running Cyanogen Mod 7.0 Stable.
(I'm going to try a long format under Windows 7 now while I'm at work, but I'll check the thread again when I'm home (about 9.30pm GMT)
Cheers
Grindboy
OK a full format under windows 7 hasn't helped. Unless anyone has a suggestion I'm going to return the card for a replacement.
EDIT: Just stuck my original 2gb SD card back in and it's working perfectly so I'm gonna email for a replacement tomorrow. I must say I'm impressed that android picked up the error rather than just spazzing out!

when does the problem start? probably it damaged when you create goldcard...?...?
No. My Hero's been rooted since the 2.1 update to too long to come out. I never needed the GoldCard. I've returned the card and I'm just waiting for a replacement now.
Having the exact problem except it's too late to return my card so I need to find a way to fix it. Got a 32gb class 6 right before I traveled. When I put files/folders onto my new sd card from my old one, most (if not all) the folders end up being empty and the most files are missing from the root when I reinsert the sd to my phone or computer. Have no clue what the problem is. I attemped an A2SD as soon as I opened the box so could that've messed it up somehow? Thanks.
I was wondering about the formatting of the card as well. First thing I did ootb was format the card using recovery. I'm thinking that might have been my big mistake. Once the new card gets here I'll try it without formatting and simply using the built in apps2sd which doesn't require a ext partition.

I'm running VR13 so i had to use old skool version of A2SD. But really, does ANYONE know what in the funk is wrong with my sd
Buggeration!
The replacement 16GB card is having the same issue. Found a forum thread here which suggests getting Windows to "check and repair" the disk. Gonna try that now, give me a minute to reboot to my windows partition and run the disk check and I'll report back.
[edit] OK that didn't help
Here's the result of the disk check. It says it found and fixed some errors:

I've emailed the merchant who supplied me with the cards (mymemory.co.uk) they are a really good company and I've used them for years so I'm certain its nothing dogdey going on. Could just be a faulty batch. I'll let you know what they suggest.
I'm having an issue with the SD card in this version. It works fine in android 2.2 thingy.

If I reinsert my SD card, It seems to give me a message saying it's been inserted. But it's still not detected. How can I fix this?
Regards.
delete your ext2 or ext3 partition.
only fat32 with 1 partition (you don't need ext2 anymore for your sdcard)
make backup of your sd card before!
I'm unsure how to do this. Also, thanks for your response. It's been total chaos for me. I guess they should've included this step in the installation process.
backup your sd card via computer then format your sd card to fat32 then try if is detected.
sory for bad english
I did that and there is still an issue.

What's the cause of this?

I've tried reflashing the rom alot of times. It's not working!
Than i dont know ask slade if he know what is wrong here.

i hope will work
Not working where is everyone!
go on development forum there you may find a solution or install CM7 gingerbread v13
Right click Computer - Manage - Disk Manager.
Then delete al the ext partions and reformat your card.
do as terrormattie.
makesure you're deleting the right partition and storage.
you can always use other tools like partition wizard to delete or create it later.

Hi, I recently had a message on my phone that my 32 GB Lexar Micro SD Card was damaged. Basically the phone could no longer read the micro SD Card. I took it out and put it in my PC card reader. It wouldn't read in the card reader, so I formatted the card using the command prompt. The SD Card was wiped clean and working again. So I put the card back into the GS3 and formatted it again with the phone for good measure. All has been fine, although a few of my MP3s had troubles reading (using stock audio player, and never had trouble before) and then just got deleted from the micro SD Card. Later I noticed these two oddly named folders in my files. One is called uATA and the other is called uPPS. But the u is not a usually looking u. You can see what I mean from the screen shot below. The two folders are at the bottom of the list. I couldn't delete these folders with my phone, but was able to delete them from my PC card reader. They have come back again. Can anyone tell me if this means my card is damaged or maybe something else. I know something is wrong for sure. Files just don't get deleted the way a few of mine have.

If I was to take a wild guess it would be something from an app you've installed or restored.
IMHO things don't write files magically, so must be an app or malware.

It is an app that probably deals with torrent data or sort of downloading **it
Here's the deal.
Today I woke up to my phone charging by the night... but it downcharged to 15% of batterry. I reboot it and find out that my SD card showed up info of being "empty". The minitool partition wizard on a PC shows me that info:

no no, the memory card is 8GB not 32MB.
How to recover the partitions? Also, the SD card has been partitioned for use with app2sd programs with this tut: http://forum.xda-developers.com/wiki/SD_card_partitioning, because my phone (HTC Explorer "Pico") has a very small amount of internal memory. The rom was stock though.
Of course I could re-format it, but I don't want to, because the data stored there was very special to me. I want to recover it.
Thanks in advance for any suggestions
I had that same problem a while back. I unmounted the SD Card and put it in another phone and it still said the same. So I soft reset my first phone, put the SD Card back in, and all was good.

But the card couldn't be recognized on a Linux, on a DMDE, SD Formatter, HP USB Disk Storage Format Tool, and primary on a TestDisk and on a GParted, and one big nothing was achieved.... You say that if I just soft reset the android phone, everything will be back to normal? Did you had the exactly same problem? You know, I need to clarify things before I do something that could destroy entirely my data.
I didn't have the exact problem just something similar and a soft reset (which will do no harm) worked for me. If the SD card can't be read any other ways then I don't know anything else other than formating the SD card.

Hello!
First of all, happy new year!
I have a problem with my Honor 7. I have a Toshiba Exceria 128 GB SD Card. When I inserted it, my phone recognized it in the parameters menus but it gave the SD Card a strange name: 1489-D352. And of course /sdcard/ cannot be found...
My configuration:
Honor 7
Build PLK-01C432B380
EMUI 4.0.1
Android 6.0
Til I didn't consider as the main storage place in the parameters, /sdcard/ can be found and it corresponds to internal storage. As soon as I declare the external sd card as the main storage, it starts malfunctionning.
As the name isn't correct, lot of applications can't find SD Card path and I have to set it manually for every application that needs to write on the SD Card.
I formated it in my phone, in my computer, exFAT or NTFS. Started the phone with the SD Card, without it, format it before, after... Nothing changes...
Can you help me, please? And forbid my english as I'm french...
i got toshiba 32 gb sdcard working fine as ext_SdCard.... android 6.0 emui 4.1
Thanks for you answer, Thelous. How does it appear when you want to access to it?

Here is what I have...
have you tried using FAT32 format?
Formatting in FAT32 is impossible from Windows. I opened a Command Windows and I launched "format J: /fs:fat32". But it takes a while to foemat 128 GB ! 3% right now.
I'll come back to give news when it's ready.
Volume is too big for FAT32...
Any other idea ?

my sd card runs on ntfs.... (changed when i was moving 5gb+ files and there was limit)
OK, I formated my sd card with NTFS file format.
If it's not main storage location, it's OK. It's named sdcard and everything is OK... Except that there's only 2GB left on main storage !
As soon as I changed my main storage location to external sd card, everything goes wrong.
But, in the third and last screen capture, you can see what Files (correct application name ???) shows: sd card. Correct name but it's the only place it appears so. In other applications, the sd card is named 9CB87....
GAAAAAAAAAHHHHH!
Coucou !
Still no idea ? As it's a real problem for me.
Anytime I insert my new sd card and wait for a while it dissapears and i re-insert but still the same.
i dont know if its my phone but it works ok when am using the pc
