FileSystem Fix

[Chris Hesselrode]

My friend took out a hard disk we had in a computer, that ran an
internal web server, threw it in a new box, as a secondary drive. Now
that I've smacked him around a bit, and put it back in the original
box, it won't boot. When doing an fsck it comes back with:

mount reload of '/' failed: No such file or directory

Can't stat /dev/ad6s1e: No such file or directory (6 times ... with
different ending letters)

How can I fix this?

In the /dev there are only:

ad4
ad4s1
ad4s1a
ad4s1b
ad4s1c
ad4s1d
ad4s1e
ad4s1f

Thanks!
