Problems mounting DOS floppy disk

Problems mounting DOS floppy disk

Post by Michal Szymans » Fri, 10 Nov 1995 04:00:00


I'm using SS20 under Solaris 2.4 with internal floppy drive. I do not
use the Volume Manager, mounting floppies & cdroms manually. Usually
everything goes fine. But ...

For a few times I have encountered following problem trying to mount
a floppy with DOS file system:

Quote:> mount -F pcfs /dev/diskette /floppy

Mount command hangs with no message given. In the /var/adm/messages file
I find following:

Nov  8 10:32:19 bulge unix: fd0: read failed (40 10 0)
Nov  8 10:32:19 bulge unix: fd0: over/underrun

After it hangs, the system starts to behave strange. I can't mount/umount
anything etc.

The only way to get out of it (in the current state of my knowledge)
is to reboot, *but* the system is not shutting down properly !!!
(probably being unable to unmount hard disk partitions). So it seems
that a small diskette can make quite a big problem, including
damaging file systems on the hard drives ;-((

Is there a way to deal with this problem?

regards, Michal.
