   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.
