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.

Last night just before plugging in my beloved SGS2 I saw that there was an icon of a microsd card with an exclamation mark on it. The phone was complaining that the card was corrupt and unusable.
Card is a Patriot brand Class 10 16GB (Yeah, I went with a cheaper model). The file system was unusable and unreadable when I tried to read the data with a micro-sd to SD adapter on my PC. I was not able to retrieve any info.
I switched to an 8GB Sandisk card from a previous phone, but am concerned now about losing data again.
Has anyone else encountered a corrupt micro-sd card on their SGS2, or a similar problem with a Patriot brand card?
Thanks!
I was facing the same problem too. reformat it and it will work again....
however the micro sd getting corrupted every month.....
now sending it for rma...
Corrupt Micro SD
I have the same problem I formatted it with my sgs2 but now I think mine is worse, my 16gb micro SD card says it has 0 bytes in windows and therefore is to small to be formatted and in osx and ubuntu it says it has 2.2 tb and has errors and cannot be formatted.
It freaking happened again! Different card now, bought a 32GB class 10 on boxing day. Just a fortnight later I've lost all the files from it!

Have you tried just taking the card out of the phone and just connecting it directly to a pc with a card reader? My card use to become corrupted when a file transfer went wrong on my phone, but I just remove it and plug it in directly to my pc and it goes back to normal.
The first time I did, couldn't be read. Keeping backups for now.

I have an 8GB SD card in my Photon that used to show up just fine, but now the contents are no longer accessible. Under file manager, it says no SD card is present. But I also use App2SD and all the apps (games mostly) that I had moved over to it are still working. I can launch those games just fine and even in the App2SD app, it shows my SD card (total space and used space) along with all the apps on it.
When I take this same SD card out and plug it into my Win7 PC, all the old contents are still there (pictures, music, videos). I can view/listen to them just fine, so the SD card is good.
So I'm not sure wtf is going on. The only thing that I did that may have caused this was installing QuickPic. When I first launched it, it tried to do an index of all my content on the SD card. But now when I launch it, it says no SD card is present. I've rebooted several times, powered off/on, reseated the SD card, but the end result is the same.
Anyone have a clue on what I should do (short of formatting starting over)?
In file manager are you browsing to /mnt/sdcard-ext ?
I was able to browse there under QQPlayer, but it was empty. For File manager, I simply select SD Card (choices are Internal Phone Storage, SD card, Shard folders) and it says "Please insert memory card". But for further testing, I installed Zedge and moved it over to the SD card with App2SD. It still allowed me to do that and the app still worked.

Keep guessing, it's a Sandisk. And like I said in the OP, it works fine in the PC and in the Photon, as far as App2SD is concerned, just not with the rest of the phone.

And you think it's a bad card exactly how? Are you reading my posts or just randomly responding with crap? If the best of your troubleshooting skills is to replace the suspect part, then point taken. However, I disagree.
So for other folks on the forum that have some basic troubleshooting skills, here's something else I've done to test. I've placed the SD card back into my old HTC Eris and the card works fine in there as well. So my guess is that the issue is somewhere in my Photon. Just not sure if it's the hardware or software.
Then live with a bad card
I have had issues with my sdcard, but not to the extent you seem to have. I swapped the Radioshack Photon for a Best Buy Photon last night to get a hunski back and backed all my apps up with astro. The only thing my new Photon recognizes are the pictures I had from the old Photon. My wallpapers, ringtones, apps, etc... are not seen by new one and Astro does not find any backed up apps. AND its a new 8gb ScanDisk. Weird.
Finally did a factory reset on my phone but still kept getting the same behavior. Called up Sprint, got a support ticket number and walked into a Sprint store for them to test it further. 2 other known good SD cards were failing to mount on my phone. Tried them on another new Photon and they worked, including mine. Luckily, I was within the 30 days period and was able to simply get my phone swapped out. POS Motorola...
OK I'm at a loss. I've searched for this issue and haven't seen anybody else experiencing this problem.
My Evo is relatively new. Had it just about a month now. Still stock. Haven't had any real problems until I bought a 32GB SD card. I've purchased 2 actually and have had the same issue with both. The phone reads the card fine supposedly. Shows 32GB available (just about). But I'm having the HARDEST time copy files to the card. I've got a ton of music, pics, ringtones, etc I'd like to get on this device. I can connect the phone to my PC, mount as a disk drive and copy to my heart's content. But then when I disconnect the phone and try to access some of those files, they're gone. I mean just GONE. The entire directory I just created with all of it contents... GONE!! Not misplaced or deleted by accident. GONE like they were never there. Like I didn't just spend 10 minutes copying 2gigs worth of files. And this happens just about every time I try. I unmount the phone properly, see the message on screen "preparing sd card" and all seems fine. But my music player says there are no files. Gallery is empty. Go back to look for the files I just copied on the card and nothing. Nowhere to be found. Now of the few hundred times I've tried this now, the directory actually stayed put a couple times. I was able to view my pics, or listen to my music. The folders stay right where I put them. But guess what. The next time I try to copy more files, my directories will disappear again. I've tried 2 different brand SD cards with the same results on both. I've used both Astro and ES to view the cards but it doesn't make a difference. I've even used and external card reader and copied files directly to the card. Still no luck. Please help. This is driving me crazy. Could this be a problem with the phone itself? I don't get it...
Well if you have used an external sd reader without success then the problem is not your phone. Your saying if you copy files to your sd,you cant see them after? So it doesn't copy from an external reader?

I strongly believe the problem is the format of your card or your computer.
If you are transferring files from your external sd reader and if its still there when you check,but gone when you insert it in your phone. Then I also strongly believe that you are looking in
/sdcard directory which you should actually be looking at /sdcard/ext_sd/
Sent from my EVO using xda premium
I'm saying that no matter if I use an external card reader, SD adapter, or connect the phone directly with a USB cable, the files I copy to the card will disappear "magically" once I dismount the card from the PC and attempt to read on the phone. Usually this is the case. But like I said, a handful of times, the files were where I put them, but disappeared the next time I tried to copy more files to the card. And no I'm not looking in the wrong directory. I know the difference between the sdcard and ext_sd folders.
What brand of cards are they? Do you have the same problem with cards of a smaller capacity?
Sent from my EVO using xda premium
This looks like a problem with your computer settings. With some configurations, if you don't explicitly eject/unmount the drive from the PC, it won't actually move the files. It will only truly copy them when you begin the eject process.
I tried a Kingston 32GB class 10 card first, then bought a generic 32GB class 10. Same issue with both. I do have a smaller 8GB SanDisk class 4 card that I have not tried yet.
I made sure to "safely remove" the cards when connected to the PC. I've tried from both a desktop and laptop. Same results all around. I thought maybe the problem is with class 10 cards but I haven't heard anyone else having issues. I also thought to try a 16GB card. But that would suck since other folks are having success with 64GB cards.
I'm about to try to reset my phone and see if that makes any difference. I may be headed back to the Sprint store this weekend.

Where did you buy these cards? This seems like a fake capacity card symptom to me. Try copying just one or two songs and see if they stay. The cards are probably fine but this is something I ran across with a friend's card before who unfortunately turned out to be a fake. I hope it's not the case for you. Also (since the cards seem to be empty for you) run this to be sure the SD card is genuine.
If you actually bought it from a reputable source, then my bad but it's best to get all bases covered.
Now if the above is not it and you had the problem with two different cards, then the issue (probably) lies with your computer/transfer cable. Try doing the reverse, copy some things on the card from the phone and try to read it on the PC. If you need something to copy you can always copy the ringtones that come with the phone at /system/media/audio/ringtones.
Let me know what you find out
I seem to recall issues initially with 32g cards acting up, but I thought only if they were a certain class but could be related? Try the 8g you have. I had issues mounting the 32g I had, class 4 I believe, when I was still on stock. Sometimes it would mount, other times it would dismount for no reason without any warning. I would just know bc I couldn't access any thing on it.

Make sure the cards are formatted Fat 32 to begin with. And yes, definitely try the smaller sd card you mentioned.

OK well here is an update.
It turns out the generic 32GB class 10 card was defective. Was able to verify that with the test utility racer posted. Thanks for that btw. I'm running the same test on the kingston card to see what it says.
I also did locate my 8GB class 4 card and that worked like a charm. No problems copying data to or from the card and definitely no disappearing directories. I just want a larger card. LOL. Hopefully the kingston one is ok after I format and test it.
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?

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.

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.

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.

Any idea if these cards have an internal "power saving" system that maybe kicks in if voltage drops below a certain level?

I read something about UHS compatibility, so I got an SD-HC

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?

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.
