There used to be a problem with older drives (say, 10 years ago) that once a drive was formatted while it was, say, horizontal, you could have problems if you later mounted it vertical - the heads/sectors on the platter might be just ever-so-much out of alignment. I've not seen this with newer drives, but this was an issue as I remember back in the sub-Gig IDE HD era.

The issue was the formatting on the drive, you could swap orientations, but to make sure things worked smoothly, it was advisable to reformat the drive in the new orientation. (the drive should be formatted in the orientation it will be installed/operated)

That's what I remember, but I never had a problem with it myself...
