Err.. I'd guess that most people who use their machine for business have sensitive data on it that can easily be at least a couple thousand dollars worth... for companies that could easily be many millions, of course. Customer databases, or strategy plans can ruin a company, if falling into the wrong hands. > If it was as easy as you describe, we'd rarely need backups. Your > disk drive crash?

It doesn't cost $9.95 but for $9950 you'd probably stand a good chance of getting (hopefully large) parts of your data back. After all, there're enough companies specialized in just that. A friend of mine did employ a data recovery company on such an incident not too long ago. mkb. P.S.: As a side note, I recommend using some kind of crypto block driver for laptops, on NetBSD I use cgd, which works very well, on FreeBSD there's gbde, although I've never used it and don't know how reliable it is. The performance hit is acceptable, with cgd, I get ca. 50% the write performance on my old Armada my700, so it doesn't really affect ordinary use. I understand that there exist similar things for Windoze aswell, don't know if it's in XP Pro out of box, aswell as probably for MacOS X.
