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). > I am not aware of the sense of "Disable UNIT attention" here, also of > the jumper "Disable T.I.Sync Negotiations". 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. -- ----------------------------------------------------------------------- Dr. Uwe Seimet http://www.linkbylink.net/
