Re: ReiserFS / 2.4.6 / Data Corruption

[Hans Reiser]

we all have different usage patterns and different needs.  I find it extremely convenient to not be
using ext2 when my dell laptop with its poor linux power management crashes frequently, or the
kernel crashes.   I have never had any problem with data corruption.  Many users I know have also
had good experiences with leaving behind ext2 and going to reiserfs on their laptops.  For your
needs and patterns though, it sounds like you need ext3.
