Can any of you think of any reason why having drives on the ATA66 bus is incompatible with having a SCSI drive?

No, there shouldn't be any interference between a SCSI bus and an ATA bus. Some ATA100 & ATA133 HDs have problems with ATA66 speed and won't be recognized on an ATA66 bus. Older Maxtor drives had a special drive utility to change the firmware on the HD to support either older slower ATA66; or faster ATA100. One Maxtor utility was called "66to100.exe", but this was a DOS-only program, and it's doubtful you need this, and even if you do, better to get a new HD than mess with this.

I don't understand why you're using the ATA66 bus for a HD? Normally the ATA66 bus would be the optical drive bus, and the ATA100 bus should support two HDs. Since there are 4 bays total, I'm assuming the OEM optical drive occupies one, the SCSI drive another, this would leave only two open bays, and that happens to be just the right number for two ATA100 HDs, so that leaves no open bays and no reason to use the ATA66 bus for a HD. If this is correct, connect the HD to the ATA100 bus and leave only the optical drive on the ATA66 bus. Should work.
