- The manuals I've gotten with several Wren drives (formerly CDC, now Seagate)
- gives a couple of recommended orientations. Nothing that precludes "using a
- desktop machine on its side like a 'tower'". (Either side.)
-
- However, they also state that the drive should be used in the same orientation
- in which it was formatted. This appeals to my common sense.
-
- otoh a friend of mine who does system integration (and probably deals with more
- drives in a week than most of us do in a year) says that he's never found that
- this matters.
-
- Nevertheless, it can't hurt to follow this rule, especially with an older drive
- whose positioner tolerances may not be as tight as they used to be.
