Reformatting external harddrive

[Daniel Underwood]

Thanks guys, this is perfect.

According to the newfs manpages, you can specify a filesystem type
(-O) and a disktype (-T) for "backward compatibility." It further
appears that -O can only designate either UFS1 or UFS2.  I don't quite
know what the -T option designates; i.e., back compatible with "what"?

(I ask about the -O and -T options becase I would like to use this
harddrive on both my FreeBSD and my linux machine.)

Thanks,
Daniel
