I have used a number of these drives, mostly in the 30Mb size.  I have found
them to be generally very good drives.  They are relatively quiet and seem to
be very reliable. There does seem to be one small problem that is particular
to this model however.  It seems that when you turn them off, sometimes the
head gets stuck to the platter (that is the explanation an engineer gave me).
When you turn them back on, they do not spin up, unless you give the computer
a good whack!  Now this only happens to some of them, and only some of the
time.  If you never turn off your computer, it will never be a problem.  This
also seems to happen less frequently if the drive is in a sidways position.
Before I set it sideways, I often had to whack my machine to get the Wren to
spin up, but the whacking never seemed to hurt anything.  Now I leave my
machine (a Unix box) on all of the time, and never have any trouble.

Apart from the aforementioned problem, I have NEVER had a problem with a Wren,
and I would actually reccomend them.
