I'm trying to take an "old clunker" (386DX/33) system and give it a new
lease on life by installing FreeBSD on it.

The system has two Seagate ST-277R (65MB RLL) hard drives.  I'm also
going to put in a couple of not-quite-so-old drives I have lying around,
using an IDE interface configured as a secondary.

I'm concerned, though, about the bad spots on the old RLL drives.  One
of the two drives appears to be error-free, but the other one has 15 or
20 bad tracks.  With DOS, this wasn't too much of a problem, but will
FreeBSD be able to deal satisfactorily with bad spots?

These drives do =not= implement the BAD144 sector-remapping protocol, as
far as I'm aware, so I can't hide the problem that way.  The best I can
do is run a low-level format, then do a media analysis and lock out the
bad tracks.

I tried installing FreeBSD with the drive with the bad spots as my root,
but "newfs" croaked after trying (unsuccessfully) to put backup super-
block info in one of the bad spots.  I got around that problem by using
the clean drive as root, but I'd still like to use the other drive and
am open to suggestions.
