Hi, I got a generic SiI card at the computer fair over the weekend and a
pair of Seagate drives (not RAIDed in any way).  Disappointed by the
performance with the pessimistic errata fix, I took a chance and
commented it out... my computer is still running and the drives are a
lot faster :)

I have nothing important on the drives yet, but I'm copying data back
and forth between them (reiserfs 3.6) to test it.  MD5 checks don't show
any problems, either.  Let me know if you have any other ideas to test
(and try to break) my setup.
