Are the following things true:
(1) It is an IDE drive?
(2) You're using FreeBSD 3.x with the "wd" driver?
(3) The drive is not running in LBA mode?

If you answer 3 × "yes":  There is a known problem with the
wd driver under 3.x when using filesystems that are larger
than approx. 27 Gbyte.  The problem might only occur if the
drive operates in LBA mode.  The symptoms can range from
failing newfs to I/O errors when accessing the filesystem.

I'd recommend that you try switching the drive to LBA mode,
then re-partition and news.  If that doesn't help, make the
partitions smaller than 27 Gbyte.

Regards
   Oliver
