Hello!
I am an owner of a 16GB MicroSD card, which I bought from a famous Greek store back in April 2012. Today I want to use this SD to my old X10 Mini phone. I put it and saw it worked, but when I removed it from the X10 Mini and put it back in my CM 9 HTC Explorer it wasn't recognised.
I inserted it to a SAMSUNG MicroSD Adapter and then to my PC and told me that "You need to format the disk in drive H: before you can use it". The capacity of my SD also showed up as 30.6 MB instead of 14.72GB. I tried recovery software such as EaseUS and Recuva, but none of them even recognised the SD. I tried formating the SD with several tools (Windows wizards, Low Level HDD Formatter, SD Formatter even using CWM) but everything failed.
Is there any way I can make my SD card usable again?
UPDATE : Also tried with HP USB Disk Storage Format Tool but it didn't work.

Nah, I think that if it was dead it would not be recognized from my PC at all.
Not true exactly, there are different failure types for SD cards:
Typical failure modes, listed in no particular order, are
Bad spot on the card (might be recoverable, maybe).
Bad spot causing the card to lock up. I.e. once you accessed that bad spot, all read attempts fail till a power cycle.
Device firmware problem causing the device to report zero capacity. This essentially renders the device inaccessible to any software.
So saying that just because it gets a drive letter that it is somehow ok is not really true.
The HP USB utility is the go-to software for fixing thumb drives with bad partition tables. You can also run "diskpart" (on windows) or gparted (on linux) to see if that is what is causing the size misrepresentation.

Hi,
just to advise:
i bought a microSDHC 8gb kingmax Class10,that i swapped with the supplied
one but after only 10 hours of my desire's use, i had a message "sd card appears as read only etc" so it's corrupted(not yet having time to format it on my laptop)
So i put my Sandisk 8gb class4 back, so far 24hours still functionnal
so perhaps a defective one
This has happened to me using my G2. I have gone through 3 SD cards and lost some very important data. It has gone as far as completely killing 2 of them and not being read by computers or data recovery machines designed to get the data back...

a couple of days ago my 16GB SD card went compltely unusable, not recognized by windows or any repairing tool
and yes I always dismount the card from the phone after unplugging the USB cable
Hi, perhaps you could tell us what brands/size were involved(editing your post) if you dont mind
@gtrab : i a newbie for android, is that important to unmount the card after unplugging the usb(shouldnt it be rather before ;-) ?

LOL yes I meant "before"
and yes, it is important to unmount any USB thumb drive or USB card reader before removing it from a Windows PC
I am not sure if this is related or not, but I found Windows trying to use the card to "accelerate windows performance" or something like that (its an option that pops up when any USB gets connected, I never enable it, but I found a windows-related file there and I just deleted it)

Hi all,
I have a 64Gig micro SD card that I formatted to exFat on my Win7 PC.
My question is, Why do I have to repair the card everytime I return it to my Win7 PC card reader to move music or videos to and from it?
Fortunately I don't loose any data but it seems like the MS exFat and the Asus exFat are not totally compatible?
Will the constant repairing limit my cards life span or worse maybe permanently damage it?

Are you ejecting the card from the 700 safely or just yanking it out?
Windows Vista/7 scream 'repair' about pretty much every data storage that has been connected to another device. You can actually just click 'continue without scanning'. It will simply proceed to load the device. (Another one of the wonderful features of Windows 7. God I miss XP.)

+1, but it can actually mount it R/O if you don't allow it to scan..

No, I guess that is a possibility, just thought exFAT was made for removable storage and finished writing to the media when the file transfer was done?

This is exactly what happens.
I'll try ejecting it from the T700, maybe android/linux mount the removable storage differently then windows and I just became accustomed to not ejecting anymore.
Funny though, it never has happened with FAT32, but my video backups are >4Gigs.
Hasn't happened to me yet on my Infinity, but happens relentlessly on my BIONIC. I even formatted the microSDCard in Windows on my computer, and it still does it. I suppose it is because of the file handling in Android, it usually starts only after I've deleted a file in any file manager in Android. And I do a lot of housekeeping on my phone, in terms of junk / old file deletions.
Could it be the same thing here?

Hello, I had Transformer about a year now. I have installed CyanogenMod 10 (JB 4.1) but the problem i have as my microSD card that I just bought will not get recognised in Transformer. I have "Samsung 32gb Class 10". It works fine if I put it thought the adaptor to the docking station and get recognised straight away. I tryed to format it to FAT32 and then insert it in the microSD slot but still same, it just does not wont to know it. I Kingston 16gb Class 2 and its absolutely the same problem. Can it be that the microSD slot it knacked since I've bought it? Please help someone.
P.S Mount SD card comes up in the Settings > Storage but after i press it in couple of minutes table says "Unfortunately, Setting has stopped"

I think that you must be right. Your sd card slot must have problem.
But before any coclusion you have to see some things. What rom do you have? Did you try it with a different clean install (after making a nandroid backup for not loosing everything)?
I have kingston 16gb class 4 and I have no problem. (FAT32)
Finally I couldn't be surprised if sd card slot is mulfumctioning from beginning cause mine has problem with internal mic from beginning.
i am on CyanogenMod 10

#1 Ensure that the contacts for the SD card are clean.
#2 Give the slot a quick blow out with some compressed air or such. NO VACUUM CLEANERS.
#3 After doing the above steps, put in the card, then power down. wait about 3 minutes, and power it back up into normal boot. These should get the device to see it and accept it. Other wise you may have gone and goofed up the locking mechanism inside that is not allowing the contacts to seat correctly. This can be resolved by a tear down and rebuild with a good service tech.

Here's a nice YT link to a tear down that should help you along with tearing it down. It's rather simple to do.

Thank you, ill have a look what is wrong inside and report back
Right, Scratch all that about disassembling it. I restored to Stock ROM.
I go to Settings > Storage and there is:
SD CARD
Mount external storage device
I press on it and its saying "Preparing external device..." but Setting freezes, after i try to copy anything on the microSD card it says "Insufficient storage". So i dont know what to do.

Plug it into the computer and see what files are there. May just need to clear out some things. BUT I am beginning to be more inclined to say that there is an issue within the card itself. If the tab can see it it should be able to mount it. If it is saying that there is not enough space, either format it via the computer and re try or take it back and tell them that it is a bad card.

There is nothing on the card, it is Formated in FAT32 and i tryed NTFS, Its a 3rd card and i dont think i am that unlucky it works in the phone, camera, pc, in tablet via docking station.

NTFS won't work. I'm sure you are aware of that. Format it from your phone, THEN put it back in the tablet. If it is still the case, then you have ruled out the card being the issue, and are back to that it could be dust / dirt / debris in the port, OR that you have a faulty port.
I revert to the stock Asus ICS ROM from there website. Reformated microSD card to FAT32 with Long formating. Wiped all data from Tablet. Insertet a card and it might show straight away or not show at all or after pressing Mount External Storage, Setting will freeze and message with Wait or Close will pop up. If the microSD mounted and the SD card sigh apper in the bottom of the screen near clock i can get in to the card and creat folders, but if i try to copy something in it, it says Insuffician Storage. So i dont think it something with the card or a port, because it can detect the card accasionly and get in to it. So is there any way to do something with the main software part, not the android it self with something that android installed to or there is nothing that android get installed to? Thank you
I've a Sandisk 64gb class 10 microsd that used to work fine. All of a sudden it has become read-only. I can read all files, but i cannot delete/add any files or format the sdcard in Android, linux or windows. Every attempt to format sdcard fails with 10+ tools I tried on PC (including gparted, fdsik, etc).
Micro-sd has no read-only switch. Is this hardware problem?

I don't know if you have been able to solve this issue, but it is the same as mine.
I can read all the files but I can't format, partition, write... nothing!
I tried any windows or linux app or distribution, Mac and PC, but nothing at all!
My microSD card is a Sandisk Ultra 64GB.
Any suggestion? Buy a new one?!?
Try HDD LLF Low Level Format Tool by HDDguru for Windows (it is for SD cards too, despite the name), and make sure that other cards work with your devices.
Or, are you using a microSD to SD adapter with all devices (Android AND pc)? If so, try a different one - they have a read-only switch. If that won't help, it indeed looks like a hardware problem - is it still under the warranty maybe?
When i had similar problem i went to service center and they replaced it without questions. These cards usually have 3-5 years warranty. give it a try

This was on of the tools I already tried with no success. I also tried different sd adapters on different PC...
I'm really thinking that it is an hardware issue of the microSD card. It should be still under warranty, the problem is that all the files are still there (and unmovable) and there are some personal documents that I'd rather not give around...

I'm starting to get a feeling that if there's the same problem with any device, software won't help. I try to always encrypt my data such as photos and saved passwords, but if OP didn't do it, there could be a problem with making use of the warranty, I have no idea how to help anymore

When I installed cromi-x everything was working perfectly but the next day my 32gb micro sd that I've been using on it since the tablet first came out stopped working for some reason, it was not getting detected anymore but if I go to settings > storage I can see "MicroSD" and the only option there is mount external storage which does absolutely nothing every time I click on it and that option with "MicroSD" disappears whenever I remove the micro sd card.
And ever since then my tablet has been waking up with like a 1 second delay, but if I remove my micro sd card it wakes up with normal speed/no delay.
First time doing this kind of stuff so not sure what's wrong...

yea, for some reason I cannot get this micro sd card to work on any pc/phone/tablet anymore, it detects it but there's nothing there for me to get into the storage let alone try to format it. I tried a different micro sd card and it works perfectly on the tablet and my sd card reader... not sure how my first micro sd broke or something after installing cromi-x, i did literally nothing to it besides putting the files in to install cromi-x

Well CROMi-X doesn't do anything to the card, so I don't see how my ROM could break it. Sounds like something corrupted or maybe the card has died. What brand is it?
There are other low level tools you can use that maybe able to rescue it but if windows can't see it you may not be able to use them.

Can you drop some names? I have a big capacity card that has refused to act its age for some time now. I've tried H2testW and the thing reported the correct storage but slowed down considerably after writing half its capacity.
You can try Gparted. You would have to burn the image to a CD or create a bootable stick and run it from there. Make sure your BIOS is set for booting from a bootable disc or USB drive before it boots Windows.

I have Gparted installed in Linux. Don't cut it. Does it low-level format? Seems pretty quick for such a chore.

Tried formatter 4. Took the whole day to erase 64GB. The program found no errors. Repartitioned it again with Gparted. Still encountered data loss. Guess the card has expired. But thanks again for the tips.
What brand/size was your card?
I had a similar experience with a cheapo 16GB card a few years ago.
Thanks,
