Your system is infected with virus and hence is not possible to unlock the processes that are accessing card.

First install Microsoft Security Essentials then install unlocker. Do a full scan and then run unlocker on the card connected to your computer, kill all process and then format it.

Good luck!

What kind of files are on the drive?
Maybe the files or volume is being held open by some application or service? While I guess there is some chance this might be a virus, there is also a good probability there is an innocent explanation.

I have exactly the same problem with my Samsung 64Gb micro SD that I bought for my ASUS TF700T Infintiy Pad. It worked fine in the pad initially but I put in my PCs card reader & my PC wouldn't read it until I formatted it. I did this using SDCard.org's 'SD Formatter v4' & now my Infinity Pad keeps getting I/O errors & won't let me put any data onto it. I tried re-formatting it in my girlfriend's Samsung SII but now it says the card is damaged!! I've just treid the card back in my PC's card reader & that will no longer read the card either, saying that the file system is corrupted!!

Is there anything I can do to salvage this card or have I just blown my hard-earned cash?? :-(
