Let me start out by saying that I have searched for any threads that have covered this, and have come up empty.
This has happened twice to me in the last two months. Running task650's V.9, which is an awesome ROM. I've got a Lexar Class 10 32gb card. Twice in two months have I booted up and the media scanner would show a broken sd card notice. I tried booting the phone without the card, and then re-installed the card. Same notice of bad sd card on boot.
At this point I took the card and stuck it in a laptop, which generated a "can not open due to corrupt or unreadable file" and "reformat drive" or something like that. I was forced to format, losing photos, vids, and TiBu folder. I synced to Dropbox and got the backup folder re-installed.
Any ideas about what could have corrupted the card? I suppose the card could be damaged. I paid good bucks, as it is not a low end card. Replace the card? Any guidance would be appreciated.
I have a Lexar Class 10 32GB card. Same issue, after first time reformatted and same thing happened a week or two later.
I did an RMA with Lexar, think there is a 1 year warranty. Got a new card, been working fine the past several months.
Ok. Thanks for the input. I've got a Kingston Class 10 on the way.
I was hoping it wasn't in the phone hardware.
Thanks, I just reminded myself to do a backup of that card itself to my PC.
Sorry to hear about your problem though.

Yeah, I lost some New Years day photos and vids with my wife. I'll NEVER find her in that good of a mood again!
It makes me wonder about my decision to place my TiBu folder on the external card, along with Nandroid backups. True, it syncs to Drop Box for TiBu but do I need the extra headache of wondering if my card is going to get smoked again? I suppose I should be backing it all up to pc..
I'm not sure but it seems to be a problem with the phone and class 10 cards.
My first one was a 16gb class 10 micro sd that one day just decided to stop working (lasted a month or so). Couldn't access it via the phone or PC.
So I went out and got a 32gb class 10 and after a month or so again it stopped working
Knowing this I refused to buy a class 10 card again. I went to Walmart and got the cheapest 32gb micro sd (Sandisk class 4) and so far so good. no problems at all
Lost everything I had too on the first 2 cards so learned the hard way to do backups to my PC.
Not the class, it's probably the brand. Some brands have terrible quality control, especially if you go for a cheaper one. I have one from Amazon Basic and it works just fine. My brother uses one from SanDisk with zero problem.
Class 10 is also newer. The technology to manufacture these is not that old. I suspect some manufacturers still need to refine their process.

Posted this on similar thread here, but want to make sure people know it's a problem:
Got a similar problem here.
Transcend Class 10 32GB Card
Works in PC, HTC Desire - no probs.
Put in Galaxy S2, it starts Media Scanning, a few seconds later reports SD Card Damaged, requires formatting.
It's right - take it back out (again, umpteenth time!), put it in PC or HTC - card is "damaged". (Nothing permanent, can reformat.)
Samsung support claim to not know anything - mind you they "play dumb" about the camera "pink spot" issue, until you challenge them to get real...
Oh, dear!

Buy a 500gb external hard drive for like 50 bucks they're cheap now. Backup everything to it once a week. Never lose data. Profit.

Sounds like a brand issue, but have you ever tried checking the drive for errors?
Given that even your PC gives you a "damaged" message, it may not work. Once inserted, go to "My Computer," get to properties, and check for errors (enable the "automatically fix file system errors" option). In the past, this has corrected "corrupted" SD cards for me.

The only corruptions I have experienced on this phone were when using MTP to transfer files from the PC. Since I stopped using MTP and use only USB Storage mounting, I have not had any more problems.
I've actually experienced this twice. Both times flashing to AOKP. I'm not blaming AOKP but just saying. The first time even my PC wouldn't read it and it needed to be reformatted. The second time my pc could read it and after nandroiding back to shostock2 it was fine.

Thanks for viewing this post.
I have been encountering a weird problem for some weeks. Whenever i reboot my optimus, memory card isn't recognized. No used/free space counter in settings, it's as if it just isn't there. Then, after some time "preparing sd card" appears in the notification center.
But the problem here is it isn't definite when will it appear- it can be after 5 minutes after booting or 7 hours. its just random. had been encountering it in cm7 for some time, thought ics would fix this problem (wiping everything). Worked like this for two days in ics.
Until tomorrow afternoon.
Now it just isn't recognizing it.
That's why i opened up my first thread.
Seems like the sd card read initialize settings are messed up. Used to be A flasher, but flashed my first ROM in two months, two days ago.
Ps: oh, and when it was getting recognized, the size of .androidsecure in root of the sd card wasn't getting analyzed, in windows it was.
Share your similar experiences, thoughts and let's come up with a solution to this one.
I think this is a hardware problem...
I believe by hardware you mean sd card. maybe but it works perfectly in windows pc, as well as Nokia phones.
Maybe the card holder (which, well, holds card in place) is acting up.
A point to be noted- other cards work flawlessly, and my card doesn't works in other phones. So, must probably (!) The memory card is the culprit.
Bought a new one altogether.

Hey all,
I thought I would share my findings to help others with the same issue.
Two days ago I kept catching glimpses of a card image in the notifications at the top of the screen, but it would only be for a second so I could not see what it was trying to tell me. But had a quick look and sd card seemed fine and all data was present on handset. A couple of hours later it popped up with "SD Card Unexpectedly Removed". I tried ejecting and reinserting,restarting device and turning off and removing battery all to no avail. So I did a quick search which showed this seemed to be quite a common issue, after reading many threads with people saying the sd card is corrupt or network providers saying it was software and to do a restore. I decided before all that hassle I would open the phone and check the circuitboard expecting it to be a dry solder joint. One thing I will point out that was different to some other users is the fact my sd card was not visible with the phone connected to the computer, so this may not solve all related issues.
THE FIX
Turn off phone, remove the battery, SIM card and sd card. Remove all screws except the one by the 3.5mm jack. Gently pull the white plastic trim that surrounds the card holders and battery but the top part with speaker and camera does not need removing. Once removed if you look to the left of the sd card holder you will see the ribbon that connects the sd card to the main circuit board and at the end of the ribbon is the connector. Mine was disconnected and was loose, even if yours is not loose it would be worth gently pulling it off and reconnecting it. Then reassemble in the reverse order.
This was a nice surprise in the sense it was a very simple fix. However when I mounted the sd card even directly in my pc it was not found, I assume that the loose connector floating about had probably shorted its connections and caused an issue with the sd card. After a handfuls of attempts at mounting it in my pc it was finally detected and I backed up all the data and reformatted the sd card, then copied the data back,mounted it in my phone and was happy to find it all working as expected.
I hope this information will help some of you out, as it was a simple fix to a simple issue and results from searching had no solutions, just lots of assumptions.
And what can I do
Hi
I read your articles and seem very good but u have a question.
I had the same issue and I saw that every time my phone said I hat message it creates in my sd card a folder named lost. I and then i saw that one part of my battery was going there, ti reconnect the phone with my sd card
I formatted my sd card and did all the things that I found in the Internetbut nnothing works and I just change my sd for another one I had and sincethere u ddon't have any other issue, but my computer detects very good my first sd card and I'm not sure how to fix it.
Any idea?
Regards
Recently ive just faced this issue, what I did is to insert my 32gb sd card in my PC and run CHKDISK, havent got any error while performing this, thereafter i inserted it in my phone & goodness till now this sd card error hasn't appear yet. (finger crossed).
Mine did something like this a few times and then the 32GB Sandisk class 10 card died. Couldn't get it to work in any device except Linux based Media player. Luckily managed to copy my nadroid backup and TB backup. Sent to Sandisk and they replaced it. There is already a thread about S3 damaging teh SD cards. May be the loose connection is what's causing the card to to end up dead.

Yeah,as mentioned I have seen a lot of issues about sd cards, this is the first issue I have had and thought it would be worth mentioning. There is little space when the case is together so it could easily still make contact and seem fine even if the connector has worked loose and cause all kinds of issues. As mentioned mine had the sd icon popping up every now and then before it actually failed. Some users seem to be going through a lot of sd cards with them failing on a regular bassis.
I've been using my 32gb card since my last phone which was the LG Optimus 3D it is a scandisk class 10 one. Anyway i took it out of the 3D and stuck it into my S3 i still have not had a problem. I did take it out a few times to put a rom in because i wiped my phone and didn't have a rom in the Sd card. Also i dropped my phone and replaced the whole front silver bumper bit the whole digitizer because i dropped my phone while playing basketball. It still works. It has been a year now it has been in two phones and still works great. I must be lucky..
I got mugged for the SD though i bought it last year for £60 from Argos a store in the UK. Now you can get them for half the price oh well.. I am waiting for the 128gb ones to come out so going to buy one lol..
today also my Sandisk Ultra HC I 32GB it's died, tomorrow I'll test with pc but no sign of life :crying: WTF samsung !!!
hey i have the same issue with an 32gb sd card, it was workking great and then i was getting the error about
"SD Card Unexpectedly Removed" and then i tried everything i could and my computer detect the sd card and it seems to be working normal but in my phone i have the error over and over again and it was draining my battery too, and the only thing i did was change to another 16gb sd card and this one is working.
maybe there is a problem with the 32gb sd cards
I have a 16GB Sandisk UHS-1 card and i have been getting this issue as well, and its becoming more and more frequent. Whenver it happens, the ringtones/notifications for certain apps like Gmail and Message get reset as the ringtones i set were stored in the sdcard. Also the photo frame app i have on my homescreen often resets to nothing as the pictures were also stored in the sdcard. Its really annoying because I can leave my phone sleeping, only to wake it up realizing my ringtones are all set to silent and my photo frame has been reset. At least i know its a common problem. damn you samsung!
Has anyone actually tried checking the connection on the ribbon as suggested? Mine has been fine since and works fine.
Does this method void our warranty? Seems so.

There is no way anyone would know you have opened it, the screws are all Philips instead of t6. As long as you use the correct screwdriver it won't damage the heads and will leave no sign of entery and it takes around 10 mins to complete. Or you could take it to Samsung to do but seems a lot of hassle for such a simple fix.
Also most people are rooted without concern of the warranty.
So there's no seals or stickers that are broken?

Nope, no sticker or seals and just so you know all screws to remove the back are identical, there are only two screws inside which are different but do not need removing for this. You only need a Philips screwdriver ( I used a ph00 x 40) as long as the screwdriver fits the screw well it will not damage the head. Once screws are out a flat head screwdriver or similar are helpfull to prise the back off.
Hi Guys,
A little feedback from my experience with this.
I too was experiencing the "Unexpectedly Removed" error on my 32GB Class10 Sandisk.
It was playing havok with my setup because I use a 8GB Ext4 Partition on the card, where I move 90% of my apps. (About 6GB of that is used by games + their "external" data), and it keeps my phone and FAT32 partition free for important stuff. (I use Link2SD and DirectoryBind)
The problem is, after the device wakes, Link2SD can't find any of the apps, so I can't start any of them, and I have to do a full reboot to get them back. :/
So, after searching and searching, I couldnt find a valid solution.
I tried with a 16GB class10 Samsung, and a 32GB Class10 Samsung card. Exact same setup. NO ISSUES.
Everything works perfectly.
Then I found this thread:
http://forum.xda-developers.com/showthread.php?t=1933743&page=2
Where most of them are experiencing this error with Sandisk cards.
Apparently, it's a known issue with Sandisk Cards (especially the 32GB models), and cards sold after December 2012 no longer experience this.
I have contacted Amazon.co.uk about replacing the card as it's only 2 months old, still waiting for their answer. Will update if anyones interested.
cheers

A curious question if I may.
Was this a SanDisk Ultra (UHS) card? Most (if not all) Android phones do not have a proper UHS-I driver today and, although the card is supposed to switch down automatically, that transition time can fool the OS sometimes.

I read something about UHS compatibility, so I got an SD-HC
http://www.amazon.co.uk/gp/aw/d/B007JTKLEK/ref=mp_s_a_1?qid=1357264092&sr=8-7&pi=SL75
Is it the same thing?
Hmmm. Ok, might be getting somewhere.
Any idea if these cards have an internal "power saving" system that maybe kicks in if voltage drops below a certain level?

Yes, the red and Grey SanDisk cards are UHS.
Yes, they definitely have controllers and the host device can command them (if it knows how). I know that they allow In System Programming (ISP) for updating firmware. They support auto-standby, power-off and sleep modes but am not certain if the card would switch without command. Check the SD link in my signature if you really need more info.

I tested my SanDisk 64GB Ultra card in a Note 2 and it had the same symptoms (Mine were worse, with the card locking up while playing music after a few minutes, causing mmc timeout errors in the kernel).
I switched to a Samsung 64GB Pro card and since then I haven't had any issue. It's also twice as fast.
The amount of headaches this SanDisk card gave me is insane, probably the last time I buy a card from them.
i have sandisk ultra class 10 32gb. try this setup. use minitool to reformat your card then set it the cluster size to 16kb.
for me so far so good. will test this in a couple of days.
Hey all. Over the past week or so, I've been experiencing a problem where randomly, a message will come up in a random task saying something like "SD Card unmounted unexpectedly, it may be damaged." Anybody else experiencing this? It is the stock SD card and I've made 100% sure it wasn't loose or anything. Think this could just be a bad SD card?

I'm running into the same problem. I've been ignoring it in hopes that it's a software issue that will get resolved whenever a JB ROM is released. Are you running a custom rom? I'm running The Base 0.7.3.
Fyi, I haven't had this problem at all in over two months of use. Ran stock for about a month and The Base rom for the past month.
Thank god other people have had it happen too. It's happened to me a lot BUT.. I had a 32gb class 4 SanDisk in my phone and that was constantly unmounting itself but I put the 16gb that came with my phone and it has yet to do it. Are you guys using a card other than what it came with?
Sent from my LG-E970
It happens to mine quite a bit, probably 7-10 times a day. I'm using a SanDisk 64GB class 10 SD card, formatted as ExFAT. Maybe I'll try switching back to the stock card to see if that has anything to do with it.
I had the same problem and switch out the card and the error stopped. I had the 32GB SanDisk Ultra and with that card it I was getting the random dismounts. I replaced it with the stock card and was working fine. I returned the SanDisk card and got a new one and it seems to be fine for about 5 days now.
What file formats are you using. My 64 GB is formatted as Fat32 and I've never had this issue. I also think that the included SD Card was pre-formatted to Fat32 which may be the reason it stopped when you switched back to it.
There you go... I've always used the stock sd card. Are you guys losing data when this happens?
This used to happen to me on my 64GB Sandisk Class 10 formatted with exFAT. I fixed it by running CHKDSK with both options checked in Windows 7. Hasn't happened since. It said it didn't detect any errors but it did something lol.
I don't believe I've lost any data. All of the songs I put on the SD card still play. I may try repairing it or using the SD card from my inspire, which may prove to be worse since I think it's only a class 4. I'll post once I figure something out.
One last thing was I tried doing a non-quick format of the card and after that my phone would not recognize that card at all until i exchanged it for a new one.
I generally don't recommend letting Windows GUI format a flash card. Google around for windows make clean, windows command line clean and format. That's your ticket right there.
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?

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

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
