I found a virus on one of my hard drives a couple of days ago, it made a hidden folder called RESYCLED/ with a file called boot.com inside there, it also made an autorun.inf file on the root of the hard drive, that ran this boot file. I thought I caught it in time and cleaned it off all of my hard drives, but I missed one as one of my hard drives shows up as being corrupted. The hard drive appears to work fine, as I can run getdataback for ntfs and could extract stuff from the drive without any problems. How can I get access to this drive to delete the boot files that I reckon are stopping the drive from booting properly?

Its an almost full 500gb drive that i really don't want to have to copy everything off of using getdataback. Any help appreciated
