I think that ext3 should be more reliable, or at least more mainstream -
I have had bad experience with raiserfs not too long ago - a crash
(similar to pull-the-plug) zeroed out completely unrelated files (files
not recently written to, just read). As I don't use Slackware anymore
(though I started usin linux on it in the dark ages before 1.0 kernel),
I don't know if the issues are fixed there.

Don't post if you happen to get better results for win32 ;)

I have a worried lung-doctor (aka pulmonologist)  friend who did some
research/statistics on influence of smoking and he is desperate as his
methodologically completely scientific studies ended up showing that
smoking is healthy and not smoking is not ;), so he seems unable to
publish any of his results in any respectable outlet ;(
