This drive, like some other IBM drives, might require the computer to 
have a SCSI ID (initiator identification). If this is the case you can 
only use it with the full-featured SCSI bus of a TT or Falcon or with a 
LINK96/97 host adapter. These are the only host adapters for the ST/STE 
which support initiator identification (SCSI ID 7).

You should disable both. Enabling unit attention can prevent the Atari 
from booting from a drive. The synchroneous transfer negotiation is not 
supported by ACSI. Only with a TT or Falcon and a driver with support 
for SCSI messages (like HDDRIVER and maybe CBHD) it can be enabled, even 
though you would not be able to profit from it with the Atari.

But anyway, provided your drive is not broken the lack of initiator 
identification with ACSI ist most likely the problem.
