I had an ext2fs drive mounted fine, and for some reason I can't get it
going again.

The drive is /dev/wd2

Output of 'fdisk /dev/wd2'
******* Working on device /dev/wd2 *******
parameters extracted from in-core disklabel are:
cylinders=790 heads=15 sectors/track=57 (855 blks/cyl)

parameters to be used for BIOS calculations are:
cylinders=790 heads=15 sectors/track=57 (855 blks/cyl)

fdisk: invalid fdisk partition table found
Media sector size is 512
Warning: BIOS sector numbering starts with sector 1
Information from DOS bootblock is:
The data for partition 1 is:
<UNUSED>
The data for partition 2 is:
<UNUSED>
The data for partition 3 is:
sysid 0,(unused)
    start 368643715, size 57 (0 Meg), flag 0
        beg: cyl 0/ sector 0/ head 0;
        end: cyl 0/ sector 1/ head 1
The data for partition 4 is:
sysid 165,(FreeBSD/NetBSD/386BSD)
    start 1, size 675449 (329 Meg), flag 80 (active)
        beg: cyl 0/ sector 2/ head 0;
        end: cyl 789/ sector 57/ head 14


Partition 4 once upon a time was an ext2fs with backups of old ~/'s I
had.

Is the data long gone at this point?  I'm still not sure why it mounted
in the past and won't mount now.

I've tried many versions of    'mount_ext2fs /dev/wd2xx /mnt' using
wd2s1...4 wd2a...d
all I get    ext2fs: /dev/wd2b: Invalid argument

I realize fdisk shows it as a FreeBSD fs now so even regular mount
doesn't work, I get bad superblock.

Baffling
