I found an interesting fact. As I already have reported, I had to
decrease the transfer rate to 8Mb/s at least to make the hard drive
boot and even with 5Mb/s transfer rate I'm experiencing an annoying
"sd0 timeout". These problems are with Micropolis 4221 (2.0G, Fast
SCSI II, 512K cache, 7200rpm). But when I replace it with HITACHI
DK312C (250M, SCSI I, 3600rpm?, old and slow), the problems above
disappeared! No timeout anymore and can happily live with 10Mb/s
transfer rate. I'm going to get a Seagate Barracuda I pretty soon, so
I'm going to test with that drive too when it comes.
