I could understand 'backing' up the drive to some other drive / media, nuking the original - and then restoring the data (e.g. dump & restore) - but just using 'dd' is going to make an exact copy of the disk :-( Isn't it? I've noticed - FreeBSD usually only fragments filesystems for a reason, i.e. low on space...
