I didn't get many responses on this one.

Dan Stromberg <> suggested using gnu tar instead
of ufsdump to do backup.

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

Thanks to them for responsding.
