Puzzlement: it sounds like you booted floppy FS then examined disk,
	but don't know how to FSCK that disk?  I think I'm missing
	something, but I'll presume not... so...

1) Boot from Floppy.  (DELETE-key out of installation script upon
	1st question.)

2) ls /mnt
	a) If /mnt directory is empty, then mount HD.
		mount /dev/fp002 /mnt
	b) If /mnt directory is NOT empty, then presumably the HD
		is mounted.
   (Some releases left it one way, some the other.)

3) Run FSCK:
	/mnt/etc/fsck -y -s /dev/rfp002    <-my style: I hate typing 'y'
		- or -
	/mnt/etc/fsck    -s /dev/rfp002	   <-for those not trusting -y
				 ^
				 +--- note the RAW disk reference.

4) reboot w/o synch-ing

Note: you shoulda run:
		df -t		<- rather than 'df'
'df -t' woulda toldja how MANY inodes were declared to exist on disk
-- a question when you're wondering about a corrupted HD.

Please inform us of the results -- we're inquiring mynds...
