I didn't get many responses on this one.

Dan Stromberg <strombrg@nis.acs.uci.edu> suggested using gnu tar instead
of ufsdump to do backup.

Rob McCauley <robmccau@RadOnc.Duke.EDU> and Arthur Darren Dunham
<add@netcom.com> both said it is not possible to skip past the
logical EOD mark with normal drives. They are right.

Thanks to them for responsding.
