I realize this may have been discussed before and I just missed it.
I may be guilty of running off at the hands too, however I have come
up with what might be a reasonable solution to the problem of the
short cables on the old Supra (and other vendors) hard drives.

I have a rather old Supra 20 meg drive which contains a 3.5" SCSI
hard disk, a power supply and a Supra AHDI to SCSI board.  The drive
is mechanically noisy and the unit tends to run hot.  I've had some
trouble with the drive due mostly to bad solder joints on the AHDI
cable connection to the Supra board.  It occurs to me that the drive
mechanism itself can be quite distant from the Supra board provided
a shielded SCSI cable.  I think I should be able to build a small
box with sufficient power to run the Supra board (or steal the power
from the power supply I already have in the enclosure) which would
fit neatly out of the way and have a SCSI ribbon cable running to
the hard drive, which would be conveniently distant so the noise
would not get on my nerves.  It also occurs to me that if this works,
someone else would have done it a long time ago...  So...  Has anyone
out there tried this approach?  I'd rather not set off on a course
which may damage my system without checking around first to see if it
is a valid one.
