.Sh DESCRIPTION
This program will take a raw disk device that covers the whole disk,
and will find all possible FFSv1/FFSv2 partitions with different block
sizes on the disk.
It will show the filesystem type (FFSv1 or FFSv2), size and offset.
It will show the file system type (FFSv1 or FFSv2), size and offset.
Also it has an option to show the values with a disklabel-alike
output.

The options are as follows:

.Bl -tag -width XXsXstartXX
