My guess is a "dud" disk.  I had problems with the 3GB Maxtor IDE (the
first 2 I got were 'bad', having symptoms just like your's).  I suspect
that an entire box of them got drop-kicked off the plane.

I tend to not use the slice abstraction terminology (ie. wd1s1e => wd1e)

wd1s1 is the slice, not a UFS partition.  This slice (s1) should have
multiple partitions (a,b,c,...)!  What does your "disklabel wd1" look
like?

Try booting a DOS disk and running SCANDISK on your drive.  I suspect
that it will come up with errors!
