there were problem reports with this particular line of hard disks from
IBM (they were replaced by a new line :
ad1: 39266MB <IC35L040AVER07-0> [79780/16/63] at ata0-slave UDMA33)

perhaps you could set up your drives one one each ata0/ata1 busses
(instead of sharing the ata0 bus)

with all recent problems on the DTLA disk line, you may not have looked
