There is an amazing pattern here. It would seem there are a great many users of Micropolis Disks and DAT tape drives who see the exact same problems I see with several adaptec controllers (2940, 1540, and others). These same people report no problems with these devices on Buglogics or NCR controllers. Several people also report they see no problems on systems with an Adaptec Segate or Adaptec Quantum pairing. So, I think there is some issue here with Micropolis / DAT drives and the Adaptec card/driver. What I am at a loss to is how to track this down. How do I go about verifing that it is a driver bug, or a SCSI incompatability between the Micropolis and the Adaptec? -- Leo Bicknell - bicknell@ufp.org System Administration - Network Design TMBG List - tmbg-list-request@tmbg.org
