Having this same problem. The card is basically brand new...installed it in my phone to backup before flashing a new ROM (thankfully I backed up to my PC as well). I think it worked once more after flashing, but the next boot resulted in the "Blank SD card..." message. I cant format it in my phone or my digital camera; Windows adds a drive letter in explorer when I plug it in, but I cant access the disk, format, etc. In a command prompt, if I attempt a chkdsk or a format, I get the message "Cannot open volume for direct access." (many others seem to have that problem, but I didnt see a resolution to it). I installed SDFormatter, but it doesnt recognize the card. It sounds like the card is toast...Im not concerned about savings files on it, just concerned about wasting $20 on a card I barely used...also, this is the second microSD card to go bad on me for no apparent reason...really dont want to keep doing this.

Ya, i lost a 64gb sd card in mine.. i even called micro sd and they cant warranty or nothing.. 90 bucks... gone.. so i would recommend getting some 2gb cards for flashing...

Is it safe to attempt to return one of these in hopes of getting my money back? Id say lasting all of 48 hours (if that) qualifies it as defective, but if the data is still on there, could a "rogue" employee with the right expertise access it? Maybe a little paranoid, but Id like to know...

[General Questions and Answers] nchall:
16 gb sdhc

Periodically my SD card will become corrupted. The chkdsk command mentioned earlier in this thread will fix it. I am wondering if anyone has an idea as to what the problem might be. Could this be fixed by deleting all partitions through gparted and reformatting? Just reformatting doesn't seem to fix it. Might it be a hardware problem with the card itself? A controller problem? Thanks.

The problem is likely a cheap card; I had this happen constantly with a 32GB Patriot class 10. No problems with any SanDisk, and their speeds have always performed at the class higher than rated for me.

That's a good indication that your card is faulty, I wouldn't persist with it, go get a new one.

Finally resolved after so many experiments !!!

Hi Guys,

Thanks for lot of comments in this thread that have helped me fix my sd card after one complete day of lots of trial and error methods.

My sd card got corrupted when i tried formatting with MiniTool and since then it was not getting detected on My Computer (not completely correct) and was always giving "Bad Disk" msg on MiniTool.

I started using lot of tools to repair my sd card but none were able to resolve the FileSystem type or format the card.

Then i looked into Device Manager and found that under "Portable Devices" ,My Sd card was recognised as "WPD FileSystem Volume driver software." with the yellow exclamation mark . From then on after bit of googling , I found windows was unable to assign this device a drive letter.

You can assign the drive letter by going to Computer Management>DiskManagement , below you would find your sc card "Unallocated Space",

Right click on the drive and click "Change Letter and Drive paths" and assign any drive .

Now windows would recognise your drive and ask to format . Well , for most people the issue resolved on formatting . but my sd card still errored out while formatting, I tried to "Create a new Volume" through "Disk management" tool but even that errored out saying "Cyclic Redundancy Check Error" .

As a last measure of resolve , i put the sd card in my Android phone , formatted and it worked :)

Not sure while creating the ,Ext3 or Linux swap partition some file got corrupted and was preventing Windows from formatting.

Another tool which was really helpful was "EasUS partition master" than "Mini Tool" as it didnt keeo saying bad disk.

Thanks All!!! and hope some of this might be useful to some people :fingers-crossed:

[General Questions and Answers] Alexbodywe:
Physically damaged?

The corrupted SD card can be damaged in two ways: physical damage and logical damage. The dad sectors, broken drive, etc, all are physical damage problem. Raw issue, inaccessible issue, undetected issue, etc, all are logical damage problem.

What is your situation?

The physically damaged card is always irrecoverable so that you have no choices but to consult a data recovery company by paying much money.

However, oppositely, the logically damaged card can be easily fixed by reformatting it and the inner data also can be recovered at the aid of a recovery tool.

Hence, if you are lucky enough, you should try a free SD card recovery tool:

squidoo.com/freeware-for-sd-card-recovery-problem2

This freeware has helped a lot as the Samsung phone memory card of me brother was logically corrupted. Now, all his contacts and photos are retrieved. So, it is really worth trying.

Note:

1. Stop using this SD card right now to avoid overwriting the original data. Any new data on it may decrease the chances of successful data recovery.

2. Save your recovered files on a different storage device in case of recovery failure.

3. Format your SD to see whether it can work well again.

4. Always back up you data in the future.

So I flashed a new kernel on my ROM and upon reboot it kept saying SD card was safe to remove. I tried going into settings and mounting and the phone would freeze for a few seconds then come back and say it was safe to remove again. It is a 64 GB microSD in my GS3. It was formatted as exFAT and worked fine until flashing the new kernel. Now when I plug the card into my Win 7 PC it says it needs to be formatted. The chkdsk method did not work as it said it couldn't perform a check on a RAW filesystem. I went into computer management > disk management and it says the drive is only 27 GB??? It is a SanDisk class 10 64 GB microSD. Any ideas or suggestions? Thanks!

Edit: I am noticing when I go into recovery the microSD is recognized and all my folders/files are present. What can I do to get it to work on the ROM without losing my stuff? Thanks!

[General Questions and Answers] DroidsConcept:
Hey guys,

So i have a unique problem with my card. It's a 64gb SanDisc class 10. I was creating a backup of my ROM using TWRP when half way through it fails and the phone restarts. Everything appeared to be fine, I could still access everything on the card. Except I can not modify any of the files. If I delete something it will delete without error, even on my computer. But then reappears as if nothing has been touched. I was able to back up the card being that everything is permanently fixed to it. I just can't add, delete, or format anything.

I thought the boot sector was damaged so I used TestDisc to try and rebuild it with no success. TestDisc gave me the same error that the chkdsk X: /R command gives me. "The /system.ext4.win entry contains a non valid link." and "The size of the /system.ext4.win entry is not valid." I don't mind loosing the data by formatting it. I just want to use my card again. Any help is much appreciated.

[General Questions and Answers] ankidroid:
I have the same problem as DroidsConcept, ledzgio and ClementNg23. I can read all the files that already were on the SD Card but it's pretty much read only now (though I can delete those files on my phone, not on PC, but they reappear later, I can also upload new files by USB when the card is in my phone, but they are unreadable). The card wasn't even removed from the phone since it put it there.

I tried pretty much everything: chkdsk and testdisk find no problems, the filesystem seems OK. I cannot format it in any way, diskpart cannot delete the partition (though it claims it did), sometimes the applications appears to be doing something but cannot finish it (for example, when I try full format in compmgmt.msc, it seems to work but when it reaches 100% it claims it was unable to finish the operation and nothing changes on the card). Some applications show the correct size of the card, some incorrect (29 GB instead of 64 GB).

Of course, I tried different adapters and also tried all this with a SD card reader directly with micro SD.

I'm not looking for a way to restore the data, just to fix the card or at least delete the data.

Safety first!

Hi all !

no matter what you try to recover your data... i would highly suggest you to make a backup of your corrupted card.

Sound strange - i know but with a valid backup of your corrupt data you always have more chances to try different methods or suggestions.

I've used Win32DiskImager to create a binary backup of my broken sd card.

.... if something goes wrong during the recovery process you're always able to write back your backup of your SD card to try another solution...

chris

I have had a problem with my SD card. While on holiday in Cambodia and Thailand my camera suddenly said : Card error, while until then I could watch back all my photos. Fortunately I had an extra SD card with me and thought: well, it will be quite easy to fix it when back in the Netherlands. Back home, I tried to open my corrupted card by putting it in the cardreader of my MacBook. I got anxious when my MacBook didn't notice there was a card inserted at all. I scanned all the fora for software to recover my card, but they all didn't find any pictures on it (if they were able to detect the card at all). At that point I decided professional hulp was needed. I sent my card to a company that could restore corrupted data on no cure no pay-basis. I got more worried when I got a message from that company that the problem was really big because the controller was corrupt. Searching for this problem on the internet, I realised that this is a BIG problem. If you want to get it restored it is very expensive and it can take a couple of 100's of Euros to get it fixed (if possible at all). I came across a company on the internet, recoverfab.com , that promised a data restore also on no cure no pay-basis. They described the problem of my card on their website so I sent my card to Germany. Two days later I got a mail that my card had arrived and that they expected to let me know if my data could be restored within two days. One day later, I got an email with a temporaray link to preview the data and how many data were restored. 100% of the files!!! Comparing to other companies this was much cheaper and the service looks great. So once you won't be able to get your card restored with downloaded programs on the internet, the controller might be corrupt on your card, and this CAN be fixed but it is too difficult to do it yourself. I found communication with them very transparant and pricing is more than reasonable and can be found easily on the website. I'm glad that I dare to send my card to another country.
