I'm afraid there's a minor confusion in the above (I should probably
go back to school and take remedial English composition). After
acquiring the old newfs and mkfs, you then have to run newfs again on
the partition. If fsck can't do it the first time, it won't be able
to do it. Note that if you're one of those people that likes to run
mkfs manually, you don't need to pull the old newfs off tape, but if
you use newfs, you *do* need mkfs, since newfs uses mkfs to do the
dirty work.

Nothing is easy to solve if you try hard enough. DoD #2525 Flamer's Hotline: (303) 678-5519
