Which IDE chipset? We ran our network on a machine runnning essentially
9.0 (cooker but with 2.4.19-16mdk kernel, and most server components and
libraries haven't changed) on a 120GB IDE disk for a week with no
problems, with dma enabled. So it might be chipset specific.

Maybe if you two can log a bugzilla or Mandrakeexpert entry, and you may
be able to try the kernel update that should be coming and see if it
addresses the problem.
