That does not look good.  But I don't think that the problem originates
with the drive.  In fact, it looks like you have a problem with your
case design - the disk is claiming to be running a lot hotter than it
was designed for.  The resulting out-of-spec expansion of all of the
disk components is probably the real cause of all of the other errors.
