I have a system here which has a 600GB JFS I: drive that is invisible at boot

behaviour that would have been run at boot time if it had been assigned a drive
letter).
I haven't tried that yet but I don't think it will help since I've ran
chkdsk in so many different ways now all to no avail. I will try it
later nevertheless.

Well, I've just tried it and:-

chkdsk /c h:
The current hard disk drive is: H:
SYS0026: The specified disk or diskette cannot be accessed.

I can't help but keep thinking that we are missing something simple
here somewhere. If I boot to the command line with Alt F1/F2 I can
use all the partitions normally but if I let the boot sequence run
normally, all 3 bootable partitions have problems.
C: hangs at the initial splash screen, G: hangs during populating
the desktop and F: completes but I can't access D:,E:,H: or I:
What else runs when booting to the desktop and does not when
interrupted by Alt F1/F2 and is there a way to stop with AltF1/F2
and then continue the boot to the desktop?
The common factor would seem to be the disk, but somehow I'm not
convinced.

When Alt-f1, then f2 to the command prompt, you can then start the shell
with the pmshell command. If everything works doing this, then the
difference is as Trevor says or in the cmd files you have executing like
startup, B4tcp, or tcpexit.

I thought about trying that but didn't have time yesterday. Anyway I've
just tried it and the desktop came up but with no open windows, no mouse
and no keyboard so I couldn't see much. See reply to Trevor.
