kaycee, as of now i couldnt find the exact website of "markvision".

but try this tool made by hp. some have used it to format their flash drives.

one more thing you can check is that when you plug the mark vision usb flash drive, if you can right click on it to see its properties -- if it says RAW or FAT/Fat32/ntfs.
