Everything was gone Includinng fdisk info and diskinfo stuff. One
interesting tidbit though:
patseal@foobar{51}# fdisk
******* Working on device /dev/rwd0 *******
parameters extracted from in-core disklabel are:
cylinders=16383 heads=16 sectors/track=63 (1008 blks/cyl)
Figures below won't work with BIOS for partitions not in cyl 1
parameters to be used for BIOS calculations are:
cylinders=16383 heads=16 sectors/track=63 (1008 blks/cyl)
Media sector size is 512
Warning: BIOS sector numbering starts with sector 1
Information from DOS bootblock is:
The data for partition 1 is:
sysid 165,(FreeBSD/NetBSD/386BSD)
start 63, size 16514001 (8063 Meg), flag 80 (active)
beg: cyl 0/ sector 1/ head 1;
end: cyl 1023/ sector 63/ head 15
The data for partition 2 is:
<UNUSED>
The data for partition 3 is:
<UNUSED>
The data for partition 4 is:
<UNUSED>
Before I refdisk'd the drive the :
sysid 165,(FreeBSD/NetBSD/386BSD)
start 63, size 16514001 (8063 Meg), flag 80 (active)
beg: cyl 0/ sector 1/ head 1;
end: cyl 1023/ sector 63/ head 15
stuff was under partition 4 (probably a bit different though). Maybe
that's why I was having all the trouble. Somehow all the drive info had
shifted or was corrupt or something.
I guess that the only left to do is to just guess the sizes of /usr and
/var and swap. Any other thoughts?
Thanks,
