Microsd's get corrupted in my Vibrant

Th weirdest thing happening on my Vibrant with Eugene R2 rom.
When I put a microSD in the slot, it can not use it past 2.19 gb (like if it was a corrupted card), but when I use the same card in my TP2 or in the SD card reader of my laptop, everything is fine. I first noticed this when I was copying over all my files and I kept getting the same errors I have had with fake cards in the past, so I tried my old faithful 8gb and sure enough, when I plug my vibrant as a USB drive, I can not navigate most folders and runing the checkdisk gives me hundreds of corruption errors. When I try to format, it tells me the max is 2.19 gb. When I take the same card (which had always been fine) and put it in the sd card reader, everything is back to normal, including attempting to format (it gives the proper size). My vibrant is doing this with all cards I have tried up till now.
Any clues?
Thanks

Did you ever run an older ULF kernel at some point? Are you running one now?
I had similar issues with both my SD card *and* the internal SD, which was causing all sorts of random system glitchiness. In my case, I suspected that this was due to the problems in early ULF kernels that caused filesystem corruption. I ended up using Heimdall (you'd use Odin if you're on Windows) to restore an official Samsung firmware, then I reformatted both SD cards, and from then on everything was fine.
There's probably a less drastic approach to be taken, but restoring to stock from Odin/Heimdall is a pretty surefire way to get rid of all the gremlins.
Incidentally, it was at that point that I decided to stop flashing anything except official or leaked Samsung ROMs until CM gets released. The price for being an early adopter is just too high

I am not sure what ULF kernels are, but all I have had is stock, then Eugene, then I did a restore to my stock backup (that screwed thigns up) so I reflashed eugene. I don't know how to use odin\can't figure out what files i should use.

Julie, I had this same problem with both this ROM, and my proceeding one, ASOPish; as have many, many others!
I too have been wanting a fix, but have not come across one. Because I am able install data onto my micro sd card via the adapter this is what I have resigned to doing. There was a mounting fix posted last month some time, but it didn't work for me, though others state that it did for them.
Sorry I couldn't give you a more workable solution, but at least, for me, this way does work.

FYI I had this problem until nero V3
Eat at Joe's

Having micro sd issues also. I tried moving some music and pics from the internal sd. It put the names but 0 data. I erase them and they come back. I reformatted the 8gb card it said 8gb free. I go back to the gallery or music player and they are all back. Check the sd with a file manager and thete they are.

hum... anyone else with this problem fix it by using nero v3?

This is happening on all 2.2 roms.
One issue was fixed, where the internal and external cards were being read opposite to what there were ..., but the issue of reading external sd above 2gigs is still there ...
If I remember correctly, this was the issue when 2.2 was released for the N1 .... they forgot to re-add support for sdhc cards... that's why they pushed 2.2.1.......

[Q] Any hope for my SD Card?

Short story: Was running the latest (as of Dec. 4-5) ICS ROM(s) - the ones with the SD card bug - and my SD card appears to be shot.
Long story:
-----
I had been using the various betas of the ICS ROMs since I noticed Tytung's first Alpha was out and the ROMs had been improving rapidly. I guess when the headphones issue was fixed it caused problems with reading the SD Card which was documented and seems to be well known.
The constant SD messages didn't bother me much, but eventually I noticed launch icons missing and went to the Market to re-download one of the apps I use (I've been flashing so much, I wasn't sure which apps I didn't bother restoring). The Market app tells me I need a SD Card to install apps, so I just figured it's just the instability of the sd card mount for this latest batch of ROMs and I'll flash an older ROM off my SD card when I get the chance. I also noticed the messages started saying I inserted a blank SD Card but I brushed it off (couldn't look into it at the time).
I get home and find out Clockwork refuses to mount my card which means I can't easily wipe and install something else, so I switch to USB storage mode in CWM to simply transfer a ROM from my PC and my PC only sees ~30mb of my 16GB SD! I initially thought it was just some corruption but I tried all sorts of format and partitioning programs and nothing recognizes more than 30mb of space and none have even been able to format that little space that's showing.
I've been Googling for a while and came up with nothing I haven't already tried so I finally decided to post here. Is there any hope for my SD card? Being the holiday season and for once I've got most of my Christmas shopping done early, I'd rather not waste the little money I have left to run out and buy another SD card right away if it's not necessary.
-----
Does anyone have any ideas how I could fix this? I'd greatly appreciate it because I now stuck with WM6.5 and realize how much I didn't miss it for the past year
This is also a heads up for testers to be sure to upgrade their ROM ASAP (or at least to the kernel that fixes this) if they're on a ICS ROM with an SD card bug. I'm not complaining - I know this is a part of testing early builds (please ignore my sorry post count; I've been flashing for quite a while) - but there's no reason for others to go through this issue if it can be helped.

Have you tried EaseUS?

Yes,
Try Easus Partition Manager and/or MiniTool Partition Manager.
They can help but you will have to format your SD card I think.
Good luck!

I had the same problem. I plugged my card into a USB reader after it working error free, it then said it needed to be formatted and was only showing 30mb. After formatting repeatedly it still doesn't read. I haven't retired any positioning software but i think the card may just be done with.

probably you'll need a replacement.
have you tried the SD formatter? there's like a 0.000001% chance it will work in your case, but why not try it?

[Q] External SD - Tab no see it.....SOLUTION FOUND SEE OP

UPDATE well it looks as though I have found a solution to my woes. I made several attempts of formatting the 2gb card in my laptop to no avail. I tried my old captivate that it originally came out of and the cappy had troubles reading it. I then stuck it in my evo and it registered instant, so I did asdcard format on my evo and then finally the tablet registers the card. In case this helps anyone else
First off someone please enlighten me on the tabs use and the way it mounts the external SD, I read somewhere that it only uses it for media files such as music books and pics. I have an 8GB that belongs in my EVO, and a 2gb that I had for my captivate I was hoping to use in my Tab for now.
Here's my story, maybe someone can shed a little light here: My tab was purchased with Stock 3.1, I was getting annoyed by the constant update request so I went ahead and rooted and installed CWM without incident, then I decided to install the Stock rooted update from here, however when I insert my SD cards they say they are unavailable. So I stick my 2gb in my laptop format to fat32 (should this be different?, typically it works in every other device I own) It still won't read, I did exactly as others point out in other threads but still I am stumped as to how the card is made available to the OS ? Now in a fit of frustration I pulled my 8gb out of my evo put the 2gb in and wham there it is, I put the 3.2 download on the 8gb popped it in tab entered CWM and flashed the update, I don't know if the 2gb is mountable in CWM I will try tonight but the 8gb was mountable through CWM however my 8gb also was not available to Android even after the update.
So what the heck is the use of the external SD and how is it used?

I think you might have an issue with your ROM,
I use my external SD for my titanium backups and other files I want to keep portable. I have used the SD card through my PC via USB and directly by putting into the PC's card reader.
Have you tried using a file manager? I use File Manager HD and the external card shows up as Storage on the left bar.
As for the filesystem, I think I may have originally formatted as FAT but I have also pulled my SD out of my Blackberry and used it to install Honeylicious through CWM,
All in all I dont think you should be having the issues that you are having...
Good luck

If it won't mount in CWM you need to format it in your android phone, that fixed it for me. Once it is formatted correctly you'll see a notification that an SD card is installed. Also my PC wouldn't see it until I put a custom rom on. Also to store items on it you can use a file manager to move things to and from it.

The 8gb card did mount in CWM but would not mount in the OS, or when it would I would get it was unavailable or sometimes even empy when I know there is only about 1 gb free space, I did not test the 2gb in CWM mainly because it was late and I needed to go to bed, but I will try tonight. The 8gb is the one I updated to rooted 3.2 with, I still need to go to 3.2.1 ? Is there a rooted Stock 3.2.1 floating around I really havent looked much into it yet

I have noticed that getting the iconia to read some sd cards is like tossing dice..Most people who have this issue says one card works perfect in every device but not in the iconia.. Some say the card will work sometimes and not others .. Some say the card works in cwm and not with file manager..
The issue here i think is that you have two CARDS THAT ARE FUSSY ABOUT mating with the iconia. OR Your rom .i would read the threads in the rom you are using.. IF still nothing that sounds like your issue ask the DEV about this.. If STILL No luck you can either try to buy a new diffrent card or flash a new rom to try and Diag. this issue..
Good luck..

Silly question
Is your microSD formatted FAT32?
If it is anything else, your unit may have trouble reading it depending on what ROM you are using - Not all ROM's are capable of reading NTFS or other file systems.
Sometimes, microSD's freak out as well, and the only way to get it back to normal is to format it in a Symbian phone (Nokia)
Also, make sure you are using the correct mount point for the card - /mnt/external_sd - Root Explorer and other apps like it can get there.
Other than that, you may just have a bad microSD, I have had many of them die for seemingly no reason.

external sd card not mounted miui

hi folks.
here's the thing. i just flashed miui 2.1.13 .32 kernel. and when i go to file explorer, i can only see my internal sd card. no matter what program i use... same. AND when i pull out extrenal sd card, phone says that there is NO sd card inserted. but when i put it back in, everything is back to same.
help? thank you

try to push the card slightly to one side or the other. That happened to me too and it was the card that wasn't making contact with the phone.

I got the solution with X5-Setting. Here ist a option for internal or external Card

awesome that helped thank you

I'm running .35 kernel, and have noticed that the last few releases of MIUI wont mount the external SD card after a shutdown & startup. It says the SD card is corrupted & needs to be formatted. I even exchanged the SD card for a new one and I still kept getting the problem. I found that rebooting the phone fixes the problem - the SD is now mounted. So it seems to only be a problem after doing a full shutdown - not a restart.

Managed to kill one of my sdcards in the latest miui, it got dced al the time and now i cant write, delete or format it. Have tried it on my laptop without luck. So be careful

Hi,
I have the same problem! If I power on the smartphone from a full shutdown my sdcard (the external one, 16 GB Sandisk) is not mounted, then if I restart the X5 Pro, Android mount correctly my external sdcard.
For this reason I wanted to change sdcard (before I had a Sandisk 4GB) with a new Sandisk 16GB sdcard. The problem is still here
How can I fix this problem?
I flashed a lot of different roms, based on B512, B540, custom gingerbread 2.3.4, Gingerbread by Genokolar, porting U8860 Huawei Honor for X5Pro, CyanogenMod 7.1 but I have always the same problem.
Please developers, find a solution because it is not a nice bug.
Regards,
kalo86

Experiencing the same problem on my U8800, MIUI 2.1.20, 2.6.35 kernel. After shutdown, the sdcard will not mount. Have to reboot to get it to work again.

Hi, I have the same problem and for this reason I opened a new thread discussing this bug.

Did you try that on Windows tools or with Unix tools?

[Q] HD2 CWM and MAGDLR can't sense/mount microSD

Ok, here's my case laid out. I've searched the forum to death, so I'm pretty sure what I have here is a head scratcher so I'm hoping someone can help me out.
I bought a used HD2 off craigslist. It came with WP7.5. When I plugged in the data cable (i.e. USB cable), I didn't get a prompt for mounting to SD card. I installed Zune and got all the drivers (going through the MS troubleshooting list), and the phone was able to mount to Zune with only 200 mb. No problem, right? This error is common. I find out that if I use an SD Formatter, I can clear the card, which is 16gb, back to it's original state by mounting the card through MAGDLR.
After restarting the phone, I still couldn't get more storage than the allotted 200 mb, except it had decreased to ~150 mb. My phone was filling up quickly. I researched that, under WP7+, there should be a "connections" option under settings for mounting the SD card through the cable, so I thought "Hey, maybe it's because this flash of WP is missing something." so I reflashed my HD2 to stock rom using a guide.
While as a stock HD2 (T-mobile), I had now 600 mb of space on the phone to use, but I noticed that the HD2 still wasn't sensing my card. Bad card, maybe? So I tried an 8 gb I had, a 2 gb I had, and a 32 gb I KNOW works from my tablet (and still works on my tablet). I decided maybe it was the ROM's fault, so I decided to flash android on it, since I'm used to android from my other phones.
So I follow Jayce's guide and put on the proper HSPL, MAGDLR, the right Radio, and CWM to flash a new android ROM and banish my problems once and for all.
PROBLEM, I'm stuck here because (dope!) even MAGDLR and CWM DO NOT SENSE MY CARD(S). Now I'm stuck and I don't know what to do. Is there a way to get it running at the very least? I know the microSD slot is pretty much the most reliable piece on the phone, so I don't think it's broken.... but maybe it is?
So either a) somebody help me get the phone running with any ROM or b) somebody help me figure out how to get the SD cards working.
Sh*t out of ideas here.
[edit] OK! I FLASHED IT USING THE OL' HOLD DOWN THE "DOWN VOLUME BUTTON AND FLASH THE STOCK" Could still really use help with the SD card sensing thing though....

it wouldn't be the first bad sd card slot reported here, so, reliable it may be, break proof it isn't.

Okay, following what has to be my 5th reformat of the same card, it worked!!!!! I quickly installed android on it. I'm not taking that card out anymore. It'll stay inside

I had a bad SDCard too, it doesn't work in recovery but does in the ROM... I think you should really think about replacing your card. Flash memory has a limited amount of writes, so I wouldn't be surprised if you lose your data or find it unusable one day.
