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...

Hi, I am going to buy Transcend TS16GUSDHC6 for p500.
My question is that if p500 will support 16gb class 6 card ? I heard that anything over 8gb slows OS as it has to read more data.
Please help me decide.
Thanks
You can go for it.

If you don't use ext partition, than you can just copy files in explorer of some other file manager, if you using it, you will need some tool, which can copy also information about ext partition.
Teoretical you can mount ext in recovery, and just do copy of all data and than restore it. Also NAND with EXT should work well.
Your mileage wrt the capcity & class of card may vary, as can be seen here - http://forum.xda-developers.com/showthread.php?t=870014

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.

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

I just put my 32GB class 4 Adata memory card into my Legend and it won't mount. Is there something I can do about it ? I'm running Cyanogenmod7. I get "SD card safe to remove" notification upon boot.
Try first to farmat that card into windows as FAT32 (full format, not quick)
It might be a good idea to boot into clockwork mod and format and partition memory card with ext and fat32.

Doesnt work after full format...
on you're pc is it working?

Did your SD Card work before or is this the first time you've tried it?
If its your first time, it is mostly likely that the SD card is not compatible. Some SD cards are not compatible on the Legend so your best solution is to buy one that is. Or if you are pretty sure it works then you can always try reflashing your rom.
If it worked before then the best solution is to reflash the rom. I had to do it once and the issue was solved.
Good luck

its formatted as fat32 so i haven't a clue whats wrong anyone have any idea
Oooooo... Your SD card is corrupted...
I don't think you can open it now...
When it asks for format in phone... Don't do it...
Connect it to a PC and then format it and pray to GOD that it runs...
There isn't much you can do with sd cards unless its a class 10

its saying it on my new xperia j i got on friday. the sd is out of my ray which it still works in and it works in my x8 just not my new j ive tried different sd cards and they all say the same. im thnking its a hardware problem but it is obviously reading something. i tried using adb pusher to see if it would push files through the phone but it said ext_card faild access denied. im so frustrated
Just try a new sdcard and tell if it works or not and is the sdcard u were using of low quality?? If yes then it maynot run on such high devices...same case happened to me, so I replaced it and new one worked like charm...

Class 4 is fine...
I myself, am using class 4 SanDisk SD card... Just buy a new SD card and it has a 5 year replacement warranty... So no need to worry...
No don't buy a class 10 SD card... It will cost 5 or 6 times more than the normal class four...
There is no need for such expenditure
Check to see how the internal memory is mounted...it may be mounted as sdcard and the sdcard mounted as ext-sd or some such thing and this is why your card is working on the Ray but not in the J. You probably should check in the J forum because if this is the case it should be common and there is probably a work around. Maybe also check the other devices in the same series (Miro & Tipo???)

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.

Update SanDisk will replace the card so as long as you have it. I wrote a review on it. Just let it update though.

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.
