Hi,
recently I have installed a second SCSI Ultra160 harddisk (40 GB)
into one of our QNX4E boxes, which already was equipped with one
18 GB SCSI U2W disk. Several problems occured:
-
when invoked the first time, QNX fdisk showed a drive geometry
of 255 heads, 63 sectors/track and 4462 cylinders; then it sud-
denly changed to 64 heads, 32 sectors/track and 35003 cylinders
(Linux cfdisk always shows 4462 cylinders without change). -
the geometry of my first disk has changed too from 2231 cylin-
ders to 17501 cylinders and I dont’t know how to switch it back.
I already have tried to specify the geometry to Fsys.aha8scsi
by “fsys -h255,63 -i”, but that did not change anything. -
when I call “mount -p /dev/hd1” no partition shows up in /dev,
but I can execute “mount /dev/hd1t77 /hd1” successfully! There
is a new /dev/h then, and when I call show_scsi the output is
(hd2 is an Iomega Jaz drive):
Device PathID Target Lun Type
//4/dev/hd0 0 0 0 Direct-Access (00)
//4/dev/hd1 0 1 0 Direct-Access (00)
//4/dev/hd2 0 2 0 Direct-Access (00)
//4/dev/tp0 0 3 0 Sequential-Access (01)
//4/dev/cd0 0 4 0 CD-ROM (05)
//4/dev/tpr0 0 3 0 Sequential-Access (01)
//4/dev/h Could not stat() (No such file or directory)
Is there any limit for the number of partitions allowed? The parti-
tion tables as seen by Linux cfdisk are:
/dev/sda

What can I do to get my old drive geometries back and to make it
work properly?
