I took my Droid Razr Maxx to a local repair shop to replace its broken screen ($279 + tax = ouch). After I left the store, I noticed that my 32gb Micro SD card was blank. I thought this was weird, but planned to just re-fill it with my music, etc., when I got home. However, I can't get it to read, much less format. I've tried two PCs (Win XP and Win 7 64bit). I've tried three SD card readers on both PCs. To be sure that the readers are working, I've tried them successfully in on both PCS with an old 2gb Micro SD card, so it's not the readers or the computers. I've also tried to format the 32gb card using the Razr itself (it sees the blank card... I tell phone to format it... nothing seems to happen... lather, rinse, repeat), but even after doing so, there's a status bar message that the SD card is "blank" or "has an unsupported filed system." When I try to copy a file from internal memory to the 32gb card using the Razr, it fails. When I cable my Razr to my PC it sees the SD Card slot as empty (if I try to copy something there, Windows says "insert disk"). The SD Card slot on the Razr is still functional, because my old 2gb card works just fine when installed in the Razr. My Razr is running Stock ICS 4.0.4, but is rooted.
Question -- Assuming that this is indeed the same 32gb card that was in my phone when I brought it in for repair, what could the repair shop have accidentally done to it that would cause it to stop functioning?
Either the shop broke it or they swapped it. I guess its the former, because surely the tech who did it would be risking his job if caught. Who wants to get fired over a $30 memory card. But I can't imagine what the tech could have done accidentally that could kill it.

Either a long exposition to sun/ magnetics/ dust// .etc can damage a memory. (in fact these artifacts are kinda sensitive)
Or it can just expire. A repair could work if it was at least being recognized by pc or card readers. But by your relate it'll not work anymore.
Cheers
I've seen microSD card die for no apparent reason. It actually happened to the 16GB card that was in my RAZR when I got it. I took the card out to give it to the original owner, and nothing - it was just dead.

I will need to try this!
Well... sorry for necro bumping this, but seeing as Micro SD's are a topic even nowadays, I'll ad my 2 cts.
My micro SD got partially damaged when I had too many programs on my Android Phone access it at the same time (Power Amp, OBB on SD, Galerie, Backup Program).
However in my case it was a fun kind of damage done:
- The data on the Disk was still readable, and I could recover most of it to a 32 GiB card (save for 2 unimportant image files).
The fun part is:
I can't format the disk, it'll always show the same content / files /size used if I plug it in again.
Deleting files does the same. Etched for infinity xD.
I'll try the magnet trick, as I wouldn't want anyone to read the card when I throw it away.

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...
I bought a no name 64GB Class 10 MicroSD card to replace my 32GB but I can't seem to get my data transferred over cleanly. I've formatted it numerous times (exFAT) both on my PC and my GNote. I have the 32GB card backed up to my PC. I've tried copying from my phone (32GB) to the PC (64GB) and vice versa. Sometimes it will go all the way through without a problem but always only some of the files and folders are copied correctly. Other times, it will throw one of several different errors and the stuff that looked had been copied will vanish. For example, this morning I was copying certain files, essentially one by one and checking in ES File manager to see if they were on the phone's external SD card (64GB) and they were. Then after doing this for a bout an hour it would hiccup and everything I'd copied over and verified with ES File Manager would be gone!?
If it matters, I'm running Windows 8 PC with 4GB ram and 1.31 TB of HD storage. On my Gnote i've tried it with both a stock ICS TW ROM and JellyBeer 4.1.0 with no joy. I've done a bunch of searches here and on Google but nothing seems on point. If it's a bad SD Card, how do I test for that?
When I had a weird problem like that it turned out the SD card was fake. This program determines your actual SD card size.
http://fightflashfraud.wordpress.co...ld-standard-in-detecting-fake-capacity-flash/
Other then that, fat32 is what you should use in Android. Maybe even try letting the phone format the card through settings/ storage. Be advised there will be data loss so backup anything beforehand.

sorry that this was the way to find out. No name high capacity SD cards would be a red flag.
I even had a couple that said Kingston 32gb which were actually 2gb. Flea bay and craigslist at its worst.
Thanks for reporting back. Hopefully more people are aware of the SD card validator link I posted now.

The validator is certainly in my toolbox now. Thanx again. It takes forever to run on the large capacity drive but it was definitely worth. The white lettering is beginning to smudge. Really low class work. I'm getting my money back . . . I think. I think the poor schlub who sold it to me bought and is selling a bunch of them. I think he now knows how exposed he is.
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.

Hi, my M5 continually breaks SD cards! It mostly happens when transferring media to the cards, or downloading things directly to them.
Before the transfer/download finishes, a notification will pop up saying the SD card is damaged, please format etc... the inbuilt format tool will not correct the card and if I reboot the M5, it says the SD card is password locked!
If I transfer the card to my PC, it cannot read it. The drive is greyed out and it says there is no disk in the drive. Disk management says it has no media and is sized at 0 bytes. Any repair utility cannot access it and chkdsk and diskpart in command prompt cannot open it either.
It has happened within a week of using a new card 3 times now, Sandisk/Samsung/Integral, doesn't matter what brand.
It's getting annoying, and expensive to replace them. Can anybody help shed any light on the situation?
this happened with my m5 10.8 lte too. 2 times.
I was able to repartition and format the sd with my pc.
but i think it's a problem with my device, not the sd.
Cant confirm this on my 10.8 WiFi, because most of the time i use my 64gb Sandisk card with an external card reader. But initially, right after purchase, i used a Anker USB-C Cable for direct transfer of files. The Huawei-provided USB-C cable is only used with the power brick. Maybe you should try a different cable? I ran into all sorts of issues regarding USB on any device if i dont use the correct cable. For me: USB != USB.
Where are you buying the SD cards? You'd be surprised how common phony, counterfeit SD cards are.
Return the M5 if you need sdcards...
Hi,
I had 3 sdcards corrupted after copying files on it (USB to computer -> file explorer -> copy to SD). Brands were 1 Transcend, and 2 Sandisks. Two of them were brand new and bought at a mall.
I can't for sure assure you it's the tablet but three SD cards broken in less than a week sounds more than coincidence for me. I looked online and many people report the same issue on Mediapad tablets.
We needed trustworthy SD card support for our operations so I simply returned the tablet and switched back to its main competitor. Never had issues with SD cards before, nor after.
Apart from that the M5 worked like a charm and everyone loved it. I just couldn't risk it a enterprise level.
If you definitely depend on SD card support, my personnal experience is to stay away from Huawei's tablets.
