I am using three IWill SIDE-100 (Highpoint 370A) controllers as my IDE interfaces, not using their RAID functionality. One Maxtor 160GB drive per channel, two channels per controller. I plan on adding hot spare as the sixth drive in the future. There's one 160GB partition on each drive. Linux version 2.4.19-pre7smp-020502b (root@production) (gcc version 2.96 20000731 (Red Hat Linux 7.1 2.96-98)) #6 SMP Thu May 2 12:15:34 CDT 2002 > >This is a dual Athlon 2000+ MP on Tyan Tiger S2466N-4 with 1GB RAM.

Actually, the card is 100-capable and the drives are 133s, but hdparm indicates that they run at 100. I've tried taking the drives down to UDMA2 (33M) with hdparm -X66, but same problem occured. I wonder if that's not the PCI getting killed with too much traffic.
