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
8gb cl6 never once had unmount. Previously on original card, unmounts several times a day

with me happens the opposite...with original sd never had an unmount....with the cl4 8gb several!howewer i'm passed a week without unmounts!
And... what about having NO SD AT ALL? Is it possible? Does it still crash the phone?
Can someone test it (I don't own the device, sorry)?

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 ??? Both fs have same 4GB filesize limits

But... Do android need an SD card (or an internal memory like the nexus S) to work properly? Or is it really possibile to boot without the SD

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...

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.

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.

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

thru the phone
Okay so I have a Sandisk 64gb sdxc and it works in my GS3 just fine as exfat. However, I would like to format it to fat32 so I can take full advantage of CWM and accessing my SD card. I have tried the following:
-CMD promt format to fat32 in windows and it formatted fine, but SG3 woud report as damaged SD card.
-Format to fat32 with swissknife and it formatted fine, but SG3 woud report as damaged SD card.
-Format with E4GT but the E4GT would not even recognize the 64GB card regardless of how it was formatted.
-Format in my Xoom but it would also not recognize the card.
So what is my solution here? Is there a way to format this card in FAT32 and use it in my GS3 or do I need to just deal with Exfat until the CM team develops an exfat compatible CWM?
If i format it to FAT32 then go directly into CWM it recognizes the card but when I boot up it still gives and SD card damaged error. Guess i will just have to deal with no CWM access if I use the 64gb card.
exactly my experience. fat32 format the phone reads it occasionally and then starts to report it as damaged.

Thanks for the verification. Either CWM will need to be made to work or I will need to go back to the 32gb card i guess.
Thought there would be more people here using the 64gb cards with thier GS3. Anyone have a work around?
I used the GUI version of Fat32 Format: http://www.ridgecrop.demon.co.uk/index.htm?guiformat.htm
Worked for me. Win7 x64 with a 64 GB Sandisk card. I'm using rooted stock AT&T ROM and it has never complained about an invalid card. CWM works fine, too.
I wonder if it'd work formatting fat 32 on a Mac. Only way a year ago I was able to format a 250GB hdd fat32 so I could backup my PS3 back then.
Tried through windows and even though I found ways to format it, it never worked right.

i had to do this earlier today for cwm purposes! use a free prog called active partition manager. i already did a nandroid also. otherwise, that exfat will give you mounting error.
use extfsd
A full format in swissknife then a quick format in Active Partition Manager is the only thing that worked for me. Got it working though!! Thanks for all the help.

This is what I used too. Other methods didn't "stick" for some reason, maybe the tools weren't actually formatting it to FAT32 but exFAT and just figured that it wouldn't matter to most people using the tool. This tool, however, worked perfectly. Haven't had any errors since using it.

Just got mine and all it says is blank sd card, and it is not willing to format it via my phone or windows as well as third party programs. Not sure what's going on. Windows formatting just says it can't, while 3rd party programs just hang forever. Any ideas?

I just had the same problem. Other than downloading some software to install FAT32, what I came up with was installing it in my Epic 4G Touch. It saw that it was blank, and then allowed me to format it.

This just ended about two hours of frustration and searching. Thanks for posting that link!
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?

Hey, thanks for the reply.
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...

Maybe I forgot to mention it but both cards are FAT32 formatted. Also, the samsung card was working just fine for a week before these issues started happening.

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.

Thank you guys for the help!
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.....
Hi, I recently reverted from KK rom to stock 2.3.3. There is a strange problem only with files on microSD. I copy files on it but at first reboot the media scanning tells me card problem (broken?). If I don't restart the files are generally played!!! I try different sd and different method of format. Any suggestion???

If you've not done a /data wipe after downgrading, that can be an issue. Else, copy the files of your sd to your PC and then format it on your galaxy player.

Nope, I have to buy new one. I have been using my card for 2 years. The card performance have been degraded due to extensive read and write, after reading your sugestion I tested the card using software called "AOMEI partition manager" and the result are degraded performance due to extensive read and write.
For information to other people with same problem; I use "persyst.sys.vold.switchexternal" mod/workarround to swap galaxy player limited storage with my 64 Gb card. This mod make the card work very very hard and degrade card performance.
Hope this information will help other people with same problem.
