In the course of installing this combination, which I hadn't tried before, I had to leave the existing system 'alone' until the SCSI bus and disk were useable, then transfer all the existing stuff (from C: and D: on the old disk) to the new Maxtor, then make the Maxtor the boot disk and reformat the old disk with newer dos (ms-dos 4.01). I readdressed the SCSI bus and loaded it at d800 - it was also necessary to change the SCSI's I/O address before the two would work together. Doing that, however, made the Maxtor disk 'disk 2' to dos, which meant I was unable to use it to boot. So - the first thing I need to learn is exactly what is it that determines which disk is '1' and which is '2' ? Is it as simple as returning the SCSI bus to C800, and moving the 6SR2 to D800, or am I grasping straws here? The second thing I need to work around/through is dos's nasty habit of re-assigning the partition designations.....when I began, Disk 1, the Miniscribe, was divided into C: and D: When I finished, the arrangement was: Disk 1 (Miniscribe RLL) Disk 2 (Maxtor SCSI) C: D:, E:, F: G: Is it possible to arrange things somehow so that sequential partitions are arranged by physical position, rather than logical, ie that C: and D: are on disk 1? Aside: When I ordered the Maxtor 100S, I understood it to be a 96-meg device. I did a low-level with the Always, and FDisk told me the Maxtor offered 88 megs. After completing the dos format, I ended up with 92.5 megs - a bit short of what had been expected. Did I err in doing the low-level with the Always bus? (I've done it with no similar problems on Seagate SCSI drives) If so, how can I correct the problem and get 96 megs? -- 1B Systems Management Limited, Nanaimo, British Columbia | kmcvay@oneb.uucp Canadian Distributor: FrontDoor Automated Mail Systems
