Thank You for the reply,

I was wondering if you might entertain my idea for the moment.  I mentioned
that the hard drive
that makes noise is wd1 on the wdc0.  It is partitioned with DOS on the
first part and FreeBSD
on the second part.  My primary drive wd0 on wcd0 does not make the noise,
nor does wd1 when
I access its DOS partition from DOS.  Could the problem lie in the way I
have partitioned the
drive?  Perhaps the DOS/FreeBSD partition is split across a cylinder. 
Maybe I should try and
partition it so that the final sector of the DOS partition is the last
sector of a cylinder and
the first partition of the FreeBSD partition is the first sector of the
next cylinder.

Also, am I issuing the correct mount command?

mount -rw -t ufs /dev/wd1s2 /mnt

should mount the second (FreeBSD) partion of drive wd1 at mount-point /mnt,
correct?

Should I try replacing /dev/wd1s2 with /dev/rwd1s2?  That is mount it as a
raw device
rather than a block device?

Any practical suggestions made in an attemp to preserve the life of my hard
drive would be appreciated.

Thank You,

JM
