There is no "unmount" command. Try "umount" without the extra 'n'.

I don't know anything about your partition table so I can't say for sure
if PartitionMagic has gone nuts or not. I do remember it had "issues"
with BSD slices, but that was about a year ago. I don't use PM so
knowing if these issues are resolved now is impossible for me.

Use the "fdisk" command on your disk to print the partition table and
show me the output. You should see something like this:
# fdisk /dev/ad0
******* Working on device /dev/ad0 *******
parameters extracted from in-core disklabel are:
cylinders=87233 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=87233 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 (0xa5),(FreeBSD/NetBSD/386BSD)
start 63, size 1012032 (494 Meg), flag 80 (active)
beg: cyl 0/ head 1/ sector 1;
end: cyl 62/ head 254/ sector 63
The data for partition 2 is:
sysid 6 (0x06),(Primary 'big' DOS (>= 32MB))
start 1012095, size 2040255 (996 Meg), flag 0
beg: cyl 63/ head 0/ sector 1;
end: cyl 189/ head 254/ sector 63
The data for partition 3 is:
sysid 165 (0xa5),(FreeBSD/NetBSD/386BSD)
start 3052350, size 84871395 (41441 Meg), flag 0
beg: cyl 190/ head 0/ sector 1;
end: cyl 1023/ head 254/ sector 63
The data for partition 4 is:
