Thanks Guys .. it was sdf1 as I suspected. Managed to grab both the critical files I needed (a Word doc and my Outlook PST file) and they are both now installed and available on my spare machine. Managed to trash the stick somehow when attempting to copy the Internet Favourites folders - seems some of them copied with zero length and now I can't write to, or delete from, the stick under KNoppix or XP. Doesn't really matter tho' as I got the files I really needed.

Thanks again for the help.
