I have a Dell Venue 8 Pro a few months ago which runs on full Windows 8.1 and I put a MicroSD 64GB (Kingston SDCX10) on it's MicroSD card slot and it is working properly. Today my cat tripped my tablet and fall solidly at it's corner, denting it and somewhat messes with the SD card, the tablet seems to be working just fine after the fall.
I suspect that it corrupts my SD card since I have enabled the Write-Caching Policy on that device and the fall might have removed the SD card unexpectedly. I tried inserting a different MicroSD on my tablet and it is just working fine so it is not on the slot itself.
What was happening when I insert my MicroSD card again is that nothing shows up on My Computer and the device isn't visible at all. I tried using CMD to chkdsk the drive but it just shows the 'Cannot open volume for direct access.' error.
Is there anything I can do to fix my SD card?
Update BlackBerry devices seems to recognize my SD card but cannot format or read it at all so it seems that was just on the card's corrupted BIOS or something. Are there any application for windows that can make it recognize and format such corruption?
Best Answer
I am guessing that you originally only tried to look at the card in something like Windows Explorer, and not with Windows Disk Management. Only the latter will show you unformatted devices; Windows Explorer won't recognize media until it has been formatted to one of the storage systems that your version of Windows recognizes.
Since your updated post shows that the card is visible on a Blackberry, you can try any of the common recovery tools for SD cards. There is an article here which lists 6 such: http://www.computerworld.com/s/article/9224577/6_data_recovery_tools_for_SD_cards_USB_drives_and_more
Of those, I have used Recuva, with success. It is relatively easy to use and, best of all, is free. However, that's a personal recommendation, which is not the purpose here. All of these tools are capable of recovering data from a card that has been corrupted.
Unfortunately, I can't walk you through a recovery process without knowing which tool you choose, but most of them are relatively intuitive.
