Suppose that I can't pay the list price of $14000 for a new 320MB disk drive in a 3620, and want to save by buying a hard disk from mail order instead of Symbolics. Drives of that size can be found for $2500. What are the drives used in a 3620 actually? Are there any problems with the physical installation? How to format the disks? Or can this be done by users at all? Hannu
