[ale] mounting drives vertically

[hbbs at comcast.net]

I actually came upon this issue before, years ago.  In turns out that only upside down is an issue, or at least it was at one time.  I looked up factory specs on some drives and some said no upside down, others didn't care.  In any case, vertical was never a problem and a great many SCSI arrays (as others have observed) have the disks vertical.  

I have lost an upside-down drive before, however.
