I spent the last few weeks trouble shooting why my phone started to have random lockups/reboots with a growing frequencey. I have through process of elimination found that my external 32gb sd card seems to be the culprit. I used it for 1 week and each day I had my phone reboot itself 5-8 times and randomly lockup while using apps to the point I had to do a battery pull. I then went all of last week and only had to restart my phone 1 time by battery pull *new app froze, found it to be poorly designed* and no random reboots on its own.
I spent last night backing up all the data on my sd card. I kept movies/music/pictures on it but did not run any apps off of the card. I told windows to format it fat32 and then test the card and it said it found no problems. I copied the videos and such back over to the card then installed it. Within 1 hour the phone had already frozen up and rebooted itself.
For reference I am currently running Trigger 3.2 Final with KB5. I have also tried with Project V *forget exact version* and with CM7. All produce the same issue.
If you can think of something else I could try I would be most grateful. I am out of ideas. Have any of you ever experienced something like this?
what brand & class is the SD card?
i saw a deal at target last weekend... $8 for a dane-elec brand 8gb class 4 microSD card at target
i bought it for my gf so she could double the capacity of her current 8gb sandisk class 2 card that she had in her nexus one.
i copied everything over to the new card and after 10 minutes her phone started acting weird. as soon as the screen timed out, it would not come back on. you could operate the phone if you guessed where the buttons were on the black screen; even answer calls!
but you could not get the screen to come back on unless you rebooted and kept it awake.
i thought it was funny that she never had issues until immediately after i put the new card in, so i powered the phone off and swapped the old one back in.
no problems for a whole day. i put the new card back in the next day and it started messing up again.
so we returned the dane-elec and i snagged a kingston 8gb class 4 and tried again. no problems.
i know hers is an N1 but i figured it could be related. good luck!
My card is a Sandisk 32gb Class 4
+24 Hour Bump back up to page 1. Still cant figure this one out.
Have you also formatted the internal and re-installed the rom?
My girlfriends phone was running Axura for like 5 months and started having issues fc/freeze/reboot. I did everything and tried different rom's and kernels still same problems. Formatted internal SD and reinstalled Axura and she's been good since May.
Back everything. Pull the titanium folder. When you reinstall just copy everything back and you should be good. Also check out Br1ck'ds Ginger Zen thread second or third post for ultra cleaning steps.

Had the same issue on project v. Random soft boots and freezes. Thought it was the rom. Tried a few things but noticed the external scanning was unusually long. Took out the card and reformat it. Evrything good again.

Yeah I have tried formatting both through phone and pc no noticible difference. It is the external card causing issues not internal. I could try to format internal but when I installed trigger last it was from a clean print to stock format reroot etc. Process. Not sure if that would be the same more or less.

Sending back to front , still cant figure this one out. I have at this point tried a 16gb card my friend has and It had some of the symptoms but not all. What would you guys do to test the SD Card?
Love me some edt, but perhaps try a different rom from abother group. Problem persists im calling hardware issue.

Okay. Got a new phone and the sd card won't recognize now. Worked once til a reboot then it doesn't show up. Can't mount or unmount. Is there anyway aside from factory rest to get it working?

Before resetting the phone try and see if your computer recognizes the card, and if it does reformat the SD card. If not, return it, you probably got a dud.
It worked before on the old SGSII. But not on the new one. Odd. Bit I s'pose it is possible

It seems like andoid plays best with cards that are in fat32 format with 32bit sectors.
I may be wrong on the sector size. Please correct me if I am. Can't find where I read that.
If you can get the card setup that way and the phone still has issues reading it, it may be the new phone.

I can't get the card to recognize on the computer, I don't have a micro SD adapter though, this was in the phone. But I know it isn't the phones SD slot, as I tried the card outta my photon, worked fine. And tried the bad card in my Photon, and nothing.
So I suspect the card is bad, just not sure how it got messed up. Still strikes me as odd. But stranger things have happened.
Sd cards do have a way of acting up in weird ways.
I would hang onto the card until you get a chance to plug it straight into a pc. Linux is best for being able to read/fix messed up partitions.

Guys I don't know what to do.. My phone is telling me my sd card is damaged and it would like to reformat it but I have allot of stuff on it
its a 64gb micro sdxc sandisc
even my computer is saying the card has an I/O error I'm really hoping there's a way to fix this as I haven't backed up the card.
don't know if this helps either but I dropped my phone last night..worked fine after..then this morning without rebooting it claimed sd card error?

You're probably screwed but...
turn off phone, pull battery, pull SD card and reinsert it. Turn on phone and see what it tells you about the card. If it's still wonky you have to resort to trying to save it on a PC. Good luck but that's why back-up is so important. The card is probably OK but the data might be hosed. Sorry.
Yeah I think I'm screwed there was so much music..like 3 years worth lmao all transferred from my old ass windows 2003 xp

Actually saw this. Worth a try. http://forum.xda-developers.com/showthread.php?t=1355528
There was a freeware tool I was thinking of, but cannot think of the name. It would fall under data recovery, there are some great software's out there.
I had the same issue once or twice, what I did was boot into my linux box and try to see if it would mount, so I could get the data off. Then format it to ext4. Next I booted into Win7 and formatted it to ntfs. Popped it into my device and it said it had to format the sd for android, lol, and it worked.
I was putting music on my P769 and when I tried playing the new music, it would say it was a unsuppoorted format, it wasnt, it was a mp3. I tried other songs that I knew that would play and none of them worked. I then restarted th app and a song would play but once I tried another song it would do the unsupported format message again. I then restarted the phone, the phone then gave me the message in the notification area saying "Blank SD Card or Unsupported file system." I then tried mounting it, with no avail, it still wont work. I then factory reseted my phone and formated the SD card, and still that same message comes up. Also, before(and after) the restart, I would try to unlock the phone by pressing the power button the screen would start t turn on but automatically shut off, or it would go to a "snow" screen, but grey. Please help I need the SD card because of this phone's microscopic amount of memory!
I forgot to add that I tried the SD card in another phone and I had the same issue...
Get a new SD card. I had similar problems with my 32gb card when I got the phone. Bought a new class 10 16gb card and it works flawlessly.

Mine is a 32gb too... I'm glad I got a good deal on it...
I did hear of other people fixing it... Or just restarting their phone multiple times... But the other problems happened right after... I was thinking that it may have been something malicious?

I got the 32gb card for like $9 on black Friday around the same time I got the phone. It was flaky right from the start, but worked in my laptops card reader. Made me think it was something with the phone. It eventually stopped working in my card reader as well. Pickup a good class 10 card and everything should be fine.

So just so we're clear, can you put the card in an SD card reader and transfer files to it from a PC? Can you play files off of it through an SD card reader to a PC (or another non-Android device)?
I'm far from an expert, but maybe try breaking the card into separate partitions with something like MiniTool Partition Wizard. The card might be formatted in a way that the phone isn't familiar with. There are a few other threads on the forums that can help suggest what kind of partition would be best for your needs.
I have a 32GB SD card, and it took me a long time of messing with this damn phone to get it to do what I wanted. Card would disappear, messages about "insufficient storage", media scanner freezing up, on and on. This phone has been one huge pain in the ass. Right now I am just using a remount script to swap my internal and external, but so far so good.
Ok guys after extensive searching...I'm having the exact same issues. I did more investigating myself. When I removed the 32gb card from the port I noticed the pins in said port were messed up, the last two looked disconnected. After fooling with it for a min I decided to use the card on my tablet to get files from it, unfortunately the tablet didn't recognize the card at all. I'm thinking my phone corrupted the sd card somehow. I have yet to try another card in my phone for fear of messing another up. I'm going to try to insert the original 32gb card and have it reformat like it's asking and see how it goes. If that fails I'm gonna try a lil 2gb card in it. Also, I've contacted LG and am awaiting a return call for a warranty repair because it looks defective, I haven't dropped the phone recently, and just bought the phone in March from Best Buy... I'll keep y'all updated on my progress and wish me luck lol!

I am having this same problem with 2 32gb SanDisk Class 10 32GB cards. They are the red ones that Amazon sells.
Luckily I have a USB adapter for micro-SD cards. I transferred my data to Kingston Class 4 32GB cards.

Alright here's my update, I have the SanDisk Ultra 16gb micro SD HC I u (red and grey), I think my sd card is going out as well, but I'm wondering if there might be more to the problem. Yesterday i took out the card and I placed it in my computer to move some file. It didn't pop up at first, I wiped it and place it back in the PC and it started working. Once done, i place it back in my cell and it was working fine. I went into CWM to flash a backup. I was doing some testing so I flashed two different backups. So today i noticed that the Sd card it not mounting, but when I'm in clockworkmod it is working fine I have rebooted and checked several times, it's mounting and operating on my PC & CWM but not when the phone is on. I'm thinking CWM might have something to do with it, not sure (might be a system restore). I was going from 4.0(ice) to 4.1(jelly) & back to 4.0. I'm currently restoring one of my jelly bean backups to see if the problem is solved.
Update:
my L9 is back on Jelly Bean and the SD card is working, it might have been a corrupted backup (or something went wrong with cwm). Md5 is good, but it's not as accurate as SHA-256 checksum. Y'all might want to check if your SD card is popping up on CWM.
Good info.
this is a problem that occurs when we upgraded from ICS to JB. once I upgraded my d card would not work. So I took it out and formatted it on the computer. Then I partitioned it with a program I have and it worked. JB and ICS having trouble with the sd card. If you go back to ics then don't reformat our you work have tip reformat when you flash jb.

So I am having a problem where my Sandisk 32GB MicroSD card is getting dismounted from the phone. It gives me an error message like "SD card has been removed. Please use the Safely Eject SD card option to prevent data loss" or something like that. Then, it finds the card and runs the media scan, which renders my card useless for that time period. The screen also turns on for a minute or so during this time. Then it stays mounted for maybe up until 5 minutes before starting over again.
This absolutely rapes my battery, taking it from a full charge to dead battery in less than two hours. I thought maybe the SD card was going bad even though it's fairly new, so I took it out and tried it on my old Motorola smartphone, and it works fine and never dismounts. So I thought perhaps it's something with my phone, so I tried an older 8GB micro SD, and it works fine without dismounting at all.
Some info. Phone is running stock 4.0.4 with root and unlocked bootloader. The 32GB SD card worked fine for maybe 3 months until this problem suddenly started. Any ideas?

It's behaving like mine did when the SD card croaked. 32GB SanDisk here as well...first SD card I've ever had die on me. I was able to get it to read, one time, on my TF101 to rescue my photos...now it won't read anywhere. I'm not sure what to tell you, except that I'd back that card up pronto, just in case...

Yeah, it was a somewhat common issue for a few of us about 4 months ago. I know blenkows and I both had it happening a lot. For me it eventually went away, not sure what the deal was, there.

My SD card wouldn't stop doing it. I just gave with it. Uploaded all my music to Google Play, put the 16 GB card that the phone came with in there. All is well now. Haven't had a problem with the card in there yet but I rarely use it now anyways. Basically just there for backups

Well thanks for the responses, I already backed up the data that was on there. I can't find my receipt for it...any idea if Sandisk is good about replaced defective cards?
I went through four RMA replacement 64gb class 10 SanDisk cards, ate the $90 loss and spent $80 on the Samsung equivalent. It's faster and I have had zero problems with it. However, I used SanDisk cards for nearly a decade before those without any problems.
The SanDisk hi capacity cards seem to not work well in the lgog. They worked fine in my card readers, just not the lgog slot.

I also had this problem with a 32gb sandisk. I RMA'd it and it happens less frequently for the new one. I'd say it happens once every few weeks now instead.
It's your card. I haven't experienced this at all n I'm using a no name class 10 32gb card. I was looking scandisk card but luckily I read the reviews n they where all negative
