"Unknown File Type" -- Corruption Problem?

[Keith.Soltys at tmx.com]

If the problem is hard-drive related, I strongly recommend getting GRC's 
SpinRite. It's a low-level disk repair utility and has saved my bacon on 
more than one occasion.

I'm not sure if it would work on an external drive (if it's though a USB 
interface). If the files are on your office PC, I'd suggest scanning that 
drive.
