    After testing the stock ROM for three weeks, without any modifications, with a 8GB Class 2 SD Card, I received not a single issue with the SD card.

    I did this, because I started having issues with ThundeRom with that same card on another Optimus S. Although he had never noticed the card eject itself. He did notice that all the apps that were moved to the sd card via a2sd in ThunderRom, would lose their icon, change back to the default icon of android, and remove themselves from the App drawer. The only fix to this was a reboot.

    Now after flashing ThundeRom back onto my phone and using his card since he turned it over to me to test with, same problem returned with in 48 hours, and now the SD card ejects itself on it's own.

    Are we sure this is not tied to a2sd? I guess it could have been a coincidence that it had not a single error in three weeks, but I don't believe in those that often.

    Stock OS w/ Xionia Kernel (005)= no SD card issues, even with the apps that froyo allowed to be moved to the sd card. 768 MHz.

    ThundeRom v1.5 w/Xionia Kernel (005)= At least one problem in any given 24hr. period, thus far. 768MHz.

    I have not checked out nRom, as I am unaware if Nick uses a2sd in his ROM.

    Beezy and KSmith say do not use app2sd under any version of ThundeROM. Refer to the TundeROM thread, especially the most recent entries after he release of v.1.6.

    I was not using app2sd from the market. I only referenced ThundeRom using a2sd, because Titanium Backup was telling me it was.

    I figured out my issue was that my card was set up through the recovery, which partitions into three partitions, 32mb swap, 512 ext4(the problem), and the remainder FAT32.

    I copied everything out of FAT32, deleted all partitions and reformatted card as FAT32, copied back old contents of FAT32. Problem fixed.

    But that still makes some sort of point. The same partitioned card did not have an issue with the stock Rom. I assume that means that the stock Rom was not attempting to use anything like ext2,3,4 or the swap. That would also draw me to the conclusion that somehow ThundeRom was trying to.

    Hi I'm having this problem with my optimus I was looking at the sprint forums and thought buying a new card would fix it but I'm having the same problems again. I've already put the card in my phone can I still make it work or do I need to buy a new one?

    I originally ran an 8GB Class 4 card in my Optimus S as soon as I got it.

    I upgraded to a 16GB Class 6 card from NewEgg for $30

    Have never had any kind of SD card issues / bad mounts / failures.

    Stay away from Class 2 if at all possible - Class 4 or Class 6 if you can!

    I have always had my cards formatted Fat-32

    Best thing to do as soon as you get a new card - re-format it on a Windows machine.

    Do a long-format - Fat-32 - it'll wipe and verify the whole card.

    Or - if you want EXT2/3/4 - download GPartEd and burn it to a CD - then use that to format/partition.

    Had a Class 2 8GB Sandisk I put in my Optimus the day I got it Nov30 '10. Worked great no problems. Rooted/cust recovery/Stockrom wasn't app heavy...

    Then today... I pulled my phone out of my pocket, and it was rebooting on it own, when it came back up it said my SD card was damaged and to reformat, won't read in any PC, gone everything gone, pics etc... Hard lesson to learn on backin' up, and I preach it to so many others too....

    I'm pretty sure there's a program for windows machines that can try to identity the bad sector and repair it which may save your data. Forgive me for not knowing any other details like name or anything but I've seen if referenced before for trying to save data off a corrupted card. Might be worth spending some google time trying to figure out.

    Well spent the afternoon googlin' and came up with nothing. Tried dozen diff programs, but I guess the card is toast.

    Windows will not recognize its existence no matter what. And the phone just says its damaged and to format. Which after a while, i eventually tried, and doesn't do anything... I hope it was just the card went bad and not phone that killed it....

    Finally got my wife's LG Opitmus M to be recognized. After a couple of days of research and buying new SD Memory as mentioned in earlier posts. The results all were the same. My wifes LG Optimus M would not recognize that there was a SD Micro Card Installed. Having a 16 GB SD Micro on my BlackBerry, I popped it out to take a closer look to see if there was any physical difference between the 4GB SD Micro and the 16GB SD Micro Card. Physically they looked the same with no differnces between the two. But when I went to pick up the 16GB Card it just felt different. Different as in it felt like it was constructed better more rigid. Then it dawned on me that maybe the reason why such a high success rate specifically to the 16GB SD MIcro card other then the speed could be because it is thicker and therefore tighter fit, making better contact with the SD Micro contact leads on the phone. I took a small piece of paper that I tore off from a Magazine. Folded it a few times until it was just a litte smaller then the SD Micro Card. Placed this piece of paper on top of the card and then brought down the securing SD Micro Chip Holder and locked it into place as you would normally to keep the SD Micro Card secured to the card reader. Viola it worked.

    I wold be curious to hear back from those that had the same issues with the device not recognizing the card perform the same fix that I have mentioned above, and let me know if it also worked for you. Please make sure that you are using at Least a 4GB SD Micro Card rated at 4 on the Speed as this is the card that I used.

    This issue is fixed on the optimus S as of the VC software release. It was an issue with the code and low class cards. After VC, even the cheapie card the phone comes with stays mounted.

    I have been using the original card that came with the phone, but after the VC update is when my started to mess up. It worked perfect before then, but every now and then since the update it will tall me it is safe to remove the SD or it tells me there is no card. weird.

    The problem I am experiencing is a little different. When I got the phone in January, I replaced the OEM card with a SanDisk 8 GB Class 4 card. It worked perfectly until the VC update. After the update, now occasionally the apps that are moved to the SD card show up as the generic Android icon and if I tap them, nothing happens. Unmounting and then mounting the card from the Settings menu fixes the problem and the proper icons appear. Go figure.

    There's a app called SDRescan out there that might help you do the same thing without having to pull the card.

    Glad to hear that the VC update will fix this problem. My SD card has been unmounting even with an 8gb class 4 card that's been reformatted (two-three times). Looks like it's time to bite the bullet and update...

    does it really matter what type of micro SD card I put into the Lg optimus s?

    What happens if you put a micros SD card that is not a Class 4?

    I ask because, the 2GB micros SD card that comes with the phone, has no sign of saying Class 4 or anything remotely close to that.

    Phones with radios V9 and below tend to have a problem with SD cards unmounting. This seems to be a problem that occurs with cards that are lower than Class 4. Not everyone experiences this problem, although there's a noticeable amount who have.

    Not to fret! There's a solution for this problem: update to VC or VD radios.

    VD is the newest one out right and hasn't posed any problems for people. However, it removes the ability to use wifi tethering without rooting.

    I believe the stock SD cards are Class 2.

    I just bought a new 8GB class 4 memory card for my phone, if I follow the steps from the original post does that mean all my files from my old 2GB will be transferred to my new 8GB??

    what would happen to all my apps+data that is stored on my 2GB when I transfer it to my 8GB?

    Hi

    This sadly did not work for me

    I had problems with my sony X10i for a long time in terms of mounting and dismounting, but they went away on their own.

    When i have recently updated my phones software it no longer reconizes my 8gb sdhc class 4 card which has worked for years in many different phones, the card is still readable on a computer and has been formated in the way that has been suggested. it does howver reconize an old 1gb standard card that i have lying around? so i'm not too sure whats wronf wit it

    Seemed to work for many others. Seems that what finally fixed it was an update from LG.

    The problem didn't go away for me after updating to VD. What seemed to solve the problem was changing the launcher from stock to Zeam launcher. I don't know why that worked, but it did (maybe it coincided with something else I did), and its a faster and leaner launcher anyway.

    This problem still happens to me every so often and I'm running VD. I'm using a Patriot 16 GB class 4 SD card.

    To fix it, I unmount the SD card and mount it again. Typically that resolves the problem for a while.

    This also worked for me, thank you! Mine was to the point where it mounted/unmounted more than several times a day... And it was saying "sd card broken"... followed the steps give in here, first time formatting the sd card failed, (i purchased a class 4, 4 gig sandisk for 10 bucks @ walmart) second time success.. But when I copied my files back over to the sd and tried it for the first time... Immediate broken sd message, went straight to the androids "clear sd card" or whatever option (where the mount feature is u know), and cleared it, its been a week and not a single problem. I have all my pictures and music backed up on the computer anyways but I've wondered if it was either a corrupt file or the card... in any case it's nice to have more storage and it seems to work faster thanks again!

    I have LS670ZVH SW version and previously had numerous daily unmounts with a Patriot 8 GB class 4 card. 1 Week ago i purchased a Samsung 16 gb class 6 micro sd card without any formatting from either phone or laptop I copied all of my data to the new card , inserted and have had no issues whatsoever. Hopefully this remains trouble free.
