You mean the drives were only 5MB/sec?  I can believe that, but the
MESH controller will do 10MB/sec sync.  I say that with a crack in
my voice, because my experience with this controller is that it
doesn't work too dang well.  With some drives it just plain can't
handle the higher speed.  But with some drives it can.  So it's hit
or miss really.  I have 4 drives capable of 10MB/sec.  The Fujitsu
and the two IBM drives work IIRC, but the maxtor does not.  Go
figure.  Setting the driver to only support 5MB/sec DID NOT solve
the problem, surprisingly enough.  You can easily test your drive by
using the "other" motherboard connector if you have a system with
two motherboard connectors on it, which my 8500 and 7600 have.  I
assume the 7500 does as well.  On the 7600 mobo, one connector is
even marked "Fast".  Heh.  Yeah, fast.
