Hi there. I've got a 32 gb Transcend SDHC class 6 card running through a USB card reader that came with it (see here for reference.) I copied some files to the card and encountered some corrupted data error originating on my hard drive which stated that some of the files couldn't be copied. Ok, not a problem, if Windows is telling me the files can't be copied, they won't be. I continued the copy command instead of canceling it and proceeded to try and copy the game folder to another computer. The folder couldn't be copied because somewhere in the directory there were corrupted files that were 0 kb.

I've now downloaded 3 separate formatting programs, including one to perform a low-level format, and not one of the formats has been successful. I even tried formatting the drive to FAT 32 on a Mac OS to no avail. I can still access every single file that was previously put on the drive, no problem. I've tried deleting all the non-corrupted data to isolate the problem areas, but every time I format after deleting, the files I deleted return.

It's a very strange corruption to say the least. The card has gone through absolutely no physical trauma.

Any assistance or suggestions would be appreciated. And no, the card is not locked :thumbsup:.

EDIT: Using the chkdsk function gives me the error "First allocation unit not valid" if that helps.
