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...
