To find out the filesystem:
# file -s /dev/da0
This will run 'file' on the contents of the drive (-s flag) instead
of the drive itself (otherwise, it would say `character device' or
something).

Some common `mount' commands you could use:
If `file' says something about DOS or Windows:
# kldload msdosfs
# mount_msdosfs /dev/da0 /mnt
If `file' says it's UFS:
# mount /dev/da0 /mnt
If `file' says it's ext2:
# kldload ext2fs
# mount_ext2fs /dev/da0 /mnt
Otherwise, send me the output of the file command above and I'll see
what I can do.
Notes:
1) If you're running 4.x, replace 'msdosfs' with 'msdos' above.
2) `mount' wants /dev/da0, not /dev/rda0.
