I have two SCSI1 devices (Archive 2150 tape and some trashy NEC 2x CD-ROM) and a SCSI2 device (Micropolis 4110S - 1gig scsi) all hanging off of the same chain ties to my 1542C. Also, the seatgate 31200 (or whatever, the 1gig Hawk drive) is supposed to be pretty good but have fairly agressive cooling requirements. So just be sure that you meet whatever cooling requirements the drive comes with. Its not as bad as their Barracudas, but I've still heard of failures. alex
