Hey there,

I am in the market for some larger capacity SCSI hard drives, but before I make the plunge, I would like some input as despite all of the reading I've done, the SCSI environment still manages to confuse me. As I understand it, if I want to use an 80-pin SCSI hard drive (like this one: Seagate Cheetah ST33704LC), I will need an 80-pin to 50-pin adapter (like this: 80-pin to 50-pin adapter) and possibly an internal active terminator (like this: LVD/SE terminator).

I have two computers, an LC 475 and a Performa 630 (with CD drive) that I want to fit with larger capacity SCSI drives. My questions are as follows:

  1. How do I know if an 80-pin to 68/50-pin adapter has termination built-in?
  2. Do I need a terminator at all? As the 630 has a CD drive, does that terminate the SCSI chain? Do I need a terminator for my LC 475?
  3. Is it possible to buy simply the hard drives and adapters and expect them to work with a patched version of Drive Setup?
  4. Does anyone have any advice on the combination of items that tend to 'just work'?
Kind regards,

Lazarus
