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...

My 4GB card is just not enough for me and when I plan to get a higher one how would I do the switch process? I'm running CM7 by Mik. Will the ROM be affected in any way when I switch cards? Can someone outline the process?
I think that the rom doesnt matters..i did it like this.....
Connect your phone to pc
Copy all folders to desktop(just copy not move)
Disconnect the phone
Turn of the phone
Change sd card
Connect again to pc and copy the files from desktop to sd card
Your done

If you are using a ext already than yes. You should also backup your apps and restore it on to the new sdcard

Just speed. Therefore class 6 is recommended
tnx feeshie
sori for the noob-ish question, but what do i do with that ext and partition" that u are talking about??^__^
Another way would be backup using custom recovery, replace new SD and partition and finally, restore ur backup
Nvr bad to copy everything to computer

A partition is used by the data2sd mod. If you haven't partitioned your card when you flashed the ROM then you won't need to partition this one. Just copy all your files in your PC and paste them on your new card.
tnx a lot!!! even though i flashed a rom, partition does not have anything to do with it, right??? so i'll just copy all the files and it's fine?
There are some ROMs that require an ext partition, but mik_os's cm7 does not require one.
Yes, just copy the files and that's it.

I have an 8 GB Class 2 SD Card, does it make a huge difference? I'm guessing as in speed your talking about phone performance? Should I not use the 8 GB I have and buy another one with a higher class or does it not matter enough to get a new one?
Don't use a class2 sdcard, it's way too slow. Class 6 or higher recommended.

If the seller has a picture of the SD card the class should be next to the amount of GB and circled. So a Class 4 should have a circled 4.

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.
sent from my legend using ICS 4.0.4 ALPHA 4.
Doesnt work after full format...
on you're pc is it working?

try to use chkflsh on your PC to test, wether all sectors are ok. May be, there are some defects.
It works perfectly in my Sansa Clip mp3 player.

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

hi
i have a 16gb sandisk class 10 sd card
for somereason now after i formatted it it cannot be recognised in windows, it shows as damaged card in my sk17i when i try format it on the phone it sits there for hours
tries eaus recovery to ormat it, it says its write protected??? is it corrupt? i managed to get it working last time this happened but i have no idea what has happened to it.
im not fussed about looking whats on it. i just want it to work again. windows wont format it. tried IHIREX boot cd.
is there a sector scanner that might run through and check it? windows disk cheking wont check for errors as its not formatted. mini partition pro shows bad disk.
very frustrating... is there a way of fixing it or do i have to buy a new card?
thanks in advance
also it says cannt do anythign with it as its a RAW drive??
If you didn't already try this,
There is a command line tool called "diskpart" which comes with windows. You have to use command prompt. Open command window and type "diskpart" . It is used to partition disks and external hard drives. It might be useful. I haven't used it much because I'm on linux. Just give it a shot.

still no go,
i can give it a drive letter. but it shows as a Raw file system, cant format in ANY program
when i do a sector scan the first block is red, then it stops at 25.867%
could it be the MBR or boot secotr gone? if so is there programs to help combat this?
Try gparted and yes it works with backtrack. In my previous comment in the "source" link a guy had the same problem as yours, the card says "write protected" and the only strong reply he got was to get the memory card replaced

nah i brought it from ebay, said 2-3 days delivery, after 4 weeks i assumed it got lost in the post so i got a refund. but sure enough 3 days later it arrived. so i dont think he will take it back. a class 10 16gb sd card is only £10, but i just dont understand how these things get corrupt and break so damn easy
ok im running ANOTHER surface scan on it now. it has got a lot further than it did before, theres about 220 red bad blocks. ini partition tool shows it as a bad disk.
before when this happened i plugged it into me xbox and configured it as a memory unit, then re formatted it on me pc but it wont do it this time.
is there a way or a program that will scan and fix bad blocks? windows cant do it because it cant pick it up as an actual memory card

You can actually use BackTrack to do what another user said to do with Ubuntu/linux. It's the same thing.

Sandisk, Ebay, and low price all point to counterfeit.
Mini partition shows it has 112 bad sectors. Is. There no way to fix it? Like certain dos programs or sd repairs.
Its wierd. When I go to cwm and mount usb it formats fine to fat 32 in windows. Then cwm crashes and its bk to spuare one. Arrrgg!

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.
