Save or throw out - ST1480N HDD edition

[Alan Perry]

Actually, for me, this could probably be expanded to "early 90s SCSI HDD 
edition".

As a collector of early 90s Sun systems, I have many Seagate ST1480N 
(aka Sun 424 drives). Starting two year ago, they all started dying. Out 
of a dozen, I am now down to one working one. Is anyone repairing/saving 
these or should I just throw them out when they fail?
