Mtd roms sometimes don't get along with some SD cards. You can try formatting in cwm. If you have a spare card try formatting and using that one.
Always use proper mounting, un mounting methods.

Mine is doing the same thing.
ok so in simple words i should...?
when you're formatting are you doing a full erase or a quick format?
you might try a full erase, check for bad sectors and what not, use easeus partiton manager, or gparted, of the sd card formatter.
Miui ate my samsung card about a month ago and it was unrecoverable.
What brand of sd card are you having problems with? stock samsung, sandisk , or kingston?
The samsung cards are known to be shotty to begin with.

my fascinate came with a san disk?
I have a 32gb San disk speed 4 that gets corrupted by the end of the day (works fine on touch wiz base roms). My Samsung 16gb micro sd seems to be the running fine on MIUI and CM7, never had a problem with it so I doubt its the brand

i doing the format by tapping on it in the pop-up at the status bar which i get when i restart my phone (after the reboot i get the pop-up that said my sd card is corrupted n i need to format it so i can use it again...). should i do it differently? and i have a sandisk sd card but it worked actually really fine when i bought it, so i dunno what happened...
so i need to do an hard format?
I had the same problem when I updated to Miui i can't remember the exact build i think week 90? Stock Samsung 16 gb... I was running stock kernel which I believe to be Jt's no? now I'm reduced to a 2bg until I get money to buy yet another card -.-
What kind of error notifications did you guys get?
If you got one saying something like bad sd card
All you need to do is unmount it, and remove it off the phone
Then reboot, and pop it back in

How did you format yours? Through the phone or using the computer? Damn formatting through the computer takes 30 min for me. I have not tried formatting through the phone yet cause I heard its one of the guarantees of frying the sd cards on EC09 days, not sure if this roms frying abilities is the same.
Btw it seem to only damage my 32GB San disk, my stock Samsung sd card is surviving MTD roms

hi guys i'm trying to find a solution for sd cards unmount on lg optimus one!!!i have a kingston 8gb cl4 and i had a 4-5 remount a day before trying this:
format with windows,choose file system fat32 and in allocation unit size choose 64 kb(should be the maximum) and give a name!
after this i had no problem for 5 days: no remount no reboot!!!
i would share this because it could be a solution....so anyone have problem may can test it!!!
there is a solid solution. buy a class 4+ micro sd..
but, kudos to you! i have a class 4+ micro sd so i can't test it out, but i'm sure others will.
btw this will kill all ur data in sdcard. backup is needed

So easy if it isn't your money that will be spent
BTW, I have a class 4 SD and it unmounts regulary, so class 4 doesn't really work.
Thanks for the tip dongimin2, I'll try it out.
before i bought kingston class 4 i had the original microsd that was shipped with optimus one and i never had problems!the problems started when i bought kingston memory!....howewer.....another day without a remount or reboot!
If speed is the problem (assuming it is), then I bet reiserfs solves the problem. That is if someone can get it to work with Android Just my opinion though.
EDIT: reiserfs for Android exists. Can someone port it for the O1? xD

Erm, this could really solve the unmount problem, I guess.
@kpbotbot reiserfs is goddamn fast..i have been it for past 5 years and not a single corrupt file ever..(MS needs to learn) having a2sd on reiserfs will be quite good and how abt using FAT and not FAT32 for saving data on SD..havent tried it but shudnt it work ???

Have you tried using the old FAT on your SD? Afaik, max sizes for FAT is about 260~. I'm going to install either Debian Testing or aptosid tonight and I'm going to try out reiserfs
On the relevant side: I hope someone ports it on our kernel :/
I formatted the card from the phone , but nothing changed...i have root + milk os 1.0 touch lag kernel , before rooting + milk os kernel , i hadn't sd unmounts...i did a nandroid backup . Should i restore it ? , but i'll loose the overlock + no touch lag.. what should i do ?
Just an update: I formatted the SD card as the original poster suggested, and it did reduced the umounts considerably, but not totally.
I stigg get a umount every 5 days or so, which is surely better than twice a day
Looking forward to Gingerbread...

I installed MIUI and stange external sd not working since last two updates.....
Also I installed Bali kernel over it....

Hey there,
for the second time now Android (KG6; has happened once on KG1 before) came up with the message "SD Card corrupted... please format".
Totally out of the blue. Nothing special has happened. I didn't take out the battery or something...
So I take out the SD, put in in my card reader and Windows has no problems with it. No error message and I can use the card as regular, reading out all data that's supposed to be there.
Last time I backed up the content, formatted the SD, put the content back on and placed it back in the phone. Everything worked fine again. But considering that this process took like an hour or so (20GB of data to move) I really don't want to do this every second week.
Does someone have an idea what this could be caused by? It is an annoying thing and I really don't want to run into it when theres no pc and card reader close by.
Any constructive thoughts appreciated!
btw, I've got this SD-Booster running on Android, which changes the cache-size for SD data. Can this cause the alleged corruption?
Now when it is working just keep using it. I don't think the problem will come back again
Best of Luck.

I have the same problem. Ubuntu and Windows has no problem with the SD card. I can even read the sd card when I put the phone into nandroid recovery mode, but after loading Android it says it is damaged.
Can anybody help with this?
Just format the sd card in fat at default allocation size and you will be good to go...
It happen due to partition coorupt in sd card... So formatting will erase the causes of partition.

Vista could not format. Managed to do it on XP. Working okay now. Luckily I always keep a backup, but still a nuisance copying over 15gb of data.
Thanks again.
I skimmed through the general thread and FAQ and couldn't find anything on this, so I figured I'd post this!
I didn't have a smaller SD card and figured nothing bad could happen, so just used my 32GB SD card and it boinked out. Thought it was done for...until today! Here's how I got it to work.
1. Make sure you have your SD card in your phone.
2. Boot into your recovery (I used TWRP and haven't tested this on Amon Ra.)
3. Mount your USB storage and go to "My Computer" to view your storage drives.
4. Your SD card should pop up as a Removable Disk that has no info. Simply format the drive, reboot into your ROM, and bam! Fully working SD card
If anyone can test this in Amon Ra and let me know if it worked, be much appreciated, thanks!
easiest way is this:
do your s-off. boot into amon ra. goto the options and format the SD card right then and there.
you're supposed to always format the card right after S-oFF, or else the slot tends to not work right or something. this is pretty much why they said to try to use an extra backup card instead of using your own personal one, so ya don't have to lose everythin
Whoops, just realized I posted this to development lol. Sorry to any mod, if you could please move it.

I couldn't even get S-Off to work, lol. I tried for about 30 minutes and ended up with a "dead" SD card. My recovery didn't even see my SD card, I just mounted my USB storage for S&Gs to see what would happen.
Something I find that really helps as well is to make sure you don't flash the Gingerbread hboot when using the S-OFF program. I didn't think it would, but it did manage to give me SD card issues until I flashed a proper ICS hboot.
I'm only mentioning this because after I S-OFFed and got the SD card issues, formatting it did nothing at all to fix the problem. Only after I got the right hboot did everything finally start working again.

I just unmounted mine in Android and formatted it with Windoze. Then I formatted it again in Android. I've corrupted SD Cards all kinds of ways. It's real easy to do if you get stupid with the overclocking/undervolting. I've formatted the 32 gig I first got for my BlackBerry 9630 a few dozen times. It's still as reliable as any other SD Card I have. Better than some, in fact. The only real good way to format a solid state memory device is to write zeros to it. If not, NAND (which your SD Card is) device write cycles can take twice as long.
guys i tried all the format methods listed above still no luck, windows states its a raw format with 0 mb available

Wanted to see if anyone else is experiencing the same issue I am.
Was using my phone and my Samsung 64GB class 10 Micro Sdcard "ejected" although it was still in the phone. It had been working fine for a week. I manually ejected and placed it back in but it will not read. I get the "Scanning/Preparing SD card" Message but it always says unavailable. Thinking that my card crapped out on my, I put a brand new Kingston class 10 64 GB sd card but experiencing the same results. Oddly enough, I have an old Class 10 Transcend 8GB card that will read. I am running the stock OS-Unlocked Boot/Rooted/S-off. Only mods I have done are flashing the released HTC kernel that is R/W. (Dont know if I need to reflash the one that came with the phone), and flashed the SD card write fix posted in this thread :http://forum.xda-developers.com/showthread.php?t=2700310
Anyone know where I can get the stock ATT kernel that may have the correct drivers for ext sd? Any suggestions?

I have a SD card reader on my laptop and it recognized the card just fine but if I put the card in the phone and plug in the phone to computer via USB, it will NOT recognize/see the card.
Im pretty sure it is a software issue. Does anyone have access or a link to the stock ATT kernel/boot.img?? I'd like to troubleshoot but forgot to make a back up before I flashed the R/W kernel released here. Thanks.
Doesnt matter if the sdcard reader sees it fine in windows, your more than likely going from windows to android, try what I suggested. If the card is not formatted @fat32 it will not be read in phone...

Went to try and reformat them again and am getting some weird results.
If i plug them directly into the computer with an adapter and use SDFormat to format them, then the M8 will read the cards? However, it only reads half the amount of memory (30gb) and I do not have an option within SDFormat to change the size. Since M8 now reads the card, I went to format it within the storage settings and once that completes, it no longer recognizes the card...?? Not sure how that is possible unless the phone is reformatting the card to a format it does not recognize..?
Use sdcard reader on laptop format fat32,set it to default size...it varies on different cards, 4 kb 8kb 16kb etc...

Thanks for the continued assistance. I have done this but still only have Half of the advertised memory. When I first installed it out of the box, it worked and showed full memory (62gb). Also, the default windows formatting tool will render the card unreadable by the M8 so im using the program called SDFormatter. Seems like I'm running in circles so I guess I'll just deal with half the memory for now. At least it works.

Use above instructions to remove all partitions from sd card. Insert into phone it will prompt you about it being damaged and ask if you want to format it. Answer yes.
If you still continue to have issues, it is most likely a hardware issue.

I tried using the above fix (disk part) but it didnt even recognize the device. L0ng story short. I was able to use BOOTICE to reformat my KINGSTON Sd card to 60 GB but my samsung only reads 30 (even though it is advertised as 64) I read that when you reformat some Samsung cards, there is a protected area that most generic formatting utilities can overwrite and render the card to half capacity. Not sure if that's the case but oh well. Got it the other card to work. Thanks so much guys! Now if I can figure out why the phone isn't turning on now.....
