[comp.periphs.scsi] *help* formatting Micropolis 1598-15 on Sun OS 4.0.3

jaffa@riekko.tut.fi (Salo Jari) (06/04/90)

we just caught a new Micropolis 1598-15 1.2Gb scsi-drive.
our system is SUN 4/370 running Sun OS 4.0.3
the drive is configured to be sd2.

we had the disk formatted, but (of course ?) wanted to reformat
it using our own format command. the disk was unlabelled, so
no way to tell HOW it was formatted...

what happened was:
---
format> format
Ready to format. Formatting cannot be interrupted
and takes 17 minutes (estimated). Continue? y
Beginning format. The current time is Mon Jun  4 10:21:54 1990

Block 3  (0/0/3), Fatal non-media error (illegal request)
failed
---

drive specifications tell:

unformatted:
nhead = 15, pcyl = 1925, bytes/track = 41664

formatted (in 1k format)
ncyl = 1922, nsect = 38

formatted (in 512 byte format)
ncyl = 1922, nsect = 72

(how does the drive know which format to use ... ?)


the format.dat entry we've been trying is:

disk_type = "Micropolis 1598-15" \
        : ctlr = MD21 \
        : ncyl = 1922 : acyl = 2 : pcyl = 1925 : nhead = 15 : nsect = 72 \
        : rpm = 3600 : bpt = 41664

so far no luck.
any help would be appreciated .
