So basically the program needed might not be accessible from the hdb
partitions. GREAT :(

OK, my new understanding so far ie:
1. Don't fsck a mounted partition
2. Boot from a CD/floppy to get cli access

I dunno, but it sure as hell is on the lilo menu if I boot from CD.

OK that's easy enough ie insert CD 1 and reboot...np.

HOW?? When the machine reboots I am presented with a lilo graphical menu
enabling me to either Boot from HDD, Installation, Installation with
ACPI disabled, Install - Safe settings, Manual install, Rescue System,
Memory Test. There is no option to go into a CLI mode???
Choosing the Rescue System option the system starts asking me about my
kb type. Right there and then I exited out of it as it looked too much
like install, and asides you said to get into a CLI.

OK understood, but getting to the CLI from CD 1 seems to be the problem
ie is there some special Susian key combination needed to access it or
something...like Ctrl-Alt-Del :)
Asides from that then how am I going to be able to issue a fsck command
like -VAa which will step through the fstab file if the fsck doesn't
know where to find it?

surprise, surprise, the system still boots OK, into linux thankfully.
hdc contained Win95 and was moved for testing purposes. It will never be
reinstalled into the linux machine. I was wondering about commenting out
those entries of hdc or even deleting them.

KWrite will do it too thankfully when logged into another X session.

so I see....but there aren't half the options listed there that are
listed on the fsck man page. I'll resort to my own written notes about this.

UPS delivers worldwide I hear :)
A little informed but still desperate to fsck (defrag?) the system. I am
trying to leave the machine on as much as possible here and so far
haven't been hit by a power outage....yet. When it does hit I am going
to need to know howto use this fsck thing immediately.
So the questions remain:
1. How to get to the CLI from the rescue option when booting off the CD?
2. How can I get fsck to walk through my fstab file if the / partition
3. What fsck -option would be the best to check and repair the fs's and
also give me verbose output and a progress bar
