I do seem to remember a point when 500GB was the drive used. Not sure how much help that is, because I don't know how much of that drive was occupied originally.

Does BIOS report the same size drive? That would be easy enogh to check.

Is there a recycle bin (deleted folder) that has not been emptied yet and may be able to be restored?
It is possible the files were just marked as deleted.. but not destroyed yet. Check the recycle bin. Be careful as they may be infected files or corrupted files. Tricky area to be playing in.

Otherwise I guess the disk check program of choice would reveal more clues. I recall you being a tech guy, so you probably have favorite programs you rely on to restore and fix a drive (?)

It does look like there is a serious problem from the clues given so far.
What I would try right away; hook the drive to another computer (preferably with another OS) to see if it reports the same thing. I have had drives work fine in XP that showed problems in Vista and Win7, so I copied the contents in XP and salvaged the data. Worth trying.

It is also possible that the virus corrupted a lot of files on that drive and now they are still there, but corrupted and possibly lost.
