My SCSI bus locks up when I want to use my DAT drive

(written by Frank Neumann)

This problem seems to be related to certain A3000 Amigas: probably only those with BootROMs. It has been discovered that if you have a DAT drive connected whose SCSI address is smaller than the smallest SCSI address of a hard disk in your Amiga, the bus will lock up very early (under AmigaOS, while the SCSI bus is being scanned: you can notice this by seeing that the SCSI LED is constantly lit and nothing happens). The solution is to use higher address for DAT drives (and maybe also for CD-ROMs) and the lower ones for direct-access media (read that as "hard disks").
