Have had this happen with some crappy hard drives I've run into over the
years.  Usually accompanies some loud clicking.  Chances are you are
trying to run in a DMA mode that the drive doesnt support, eg UDMA(100)
instead of UDMA(66) or the like.  Check your BIOS, if you have
configured your hard drives by hand you may have have a wrong setting.
Consider either letting your BIOS autodetect or passing values to the
kernel at boot time.  If this doesn't work I would like to see your
dmesg output, specifically where the kernel detects your drives and ide
controller(s).
