Does anybody in NetLand have any information or suggestions on how to connect a Maxtor 8760S drive to an Amiga with an A2090 (not a) controller? The specs for the drive are 15 heads, 54-512 byte sectors per track, 1,632 cyliders. I've tried various combinations of surfaces/tracks/sectors to no avail. From using the drive specs to 2 surfaces, 25 sectors & 4 heads, 17 sectors. The drive APPEARS to prep (the drive select indicator comes on for about 25 mins, no matter how many cylinders/heads/sectors you tell it in the mount list). I've tried it with SCSI address 0 and RES2/DH2 and DH2 does't appear after the reboot. With the SCSI address 0, I tried to use RES3/DH3 which failed prep as expected and worked when the SCSI address was set to 1. The drive again went active for 25 minutes. I re-booted, mounted DH3 defined to have 4 heads 17 sectors/track, LowCyl=2, HighCyl=2 (or whatever you please, the results were the same). No problems reported by Mount either time or prep. Trying to "Format DH3: name Test" gives a "Format failed: error during format" on the first cylinder. DH3: appears in the device list, but with no disk present. This is all reproducable using RES2/DH2 under similar circumstances. The hardware checks out when it is connected to a Sun workstation. Formats, read and writes without difficulty. Could the hddisk.device be at fault? It is 8204 bytes long with a date of 23 Jan 88. HDDISK is 9436 bytes long with a date of 03-Aug-88. To further complicate the issue, I am also using the ST506 interface. Is there another controller that would be better able to cope with this problem ? Thanks in advance for your time and trouble.
