DES is strong enough. In fact, you have to choose very carefully, if
you want to get weak keys... :-) There are only 4 weak keys in the
whole 2^56 keyspace...

To those who are suggesting that encrypting the hard disk makes the
system "secure": please, don't forget that security and secrecy is not
one and the same thing. Security also includes integrity, reliability,
and availability. And, on a PC I can boot from a diskette and format
the whole encrypted partition without problems! Therefore, the
encrypted partitions help improving the secrecy of the system, not the
security...

Vesselin
