Macintosh Performa 475 replacement HDD

Unread postby paulfred » Fri Oct 13, 2017 5:44 am

I recently acquired a beautiful Performa 475 for free and at first the machine seemed to be in perfect working order. I managed to boot into System 7 just fine and played around with a few games the previous owner had installed - when suddenly the HDD (a Quantum ProDrive ELS) made a horrible grinding sound and died a rather painful death.
Now I'm looking for a replacement HDD but I'm not entirely sure which drives are compatible? Furthermore, considering that every compatible drive probably is about 25 years old wouldn't it be safer to invest in something like a SCSI2SD?

The Performa 475 is a very solid machine. It's basically the same machine as a Quadra 605, only marketed toward consumers instead of businesses. Back in the 90s, I had a Quadra 605 running OS 8.1, AppleShareIP, and FileMaker Pro as a department file server, license server, and light duty web-based database server. It was surprisingly quick and very reliable. IIRC, it had 36 MB of RAM.

Anyway, the standard internal drive is a 3.5" low-profile 50-pin narrow SCSI drive. You should be able to find low capacity drives easily enough (the original machine shipped with hard drives ranging from 80 to 250 megabytes), but the SCSI2SD approach has its charms (including lower noise) and should work fine. There are a few web pages out there describing various SCSI2-whatever adapters on Macs of similar vintage.

I also really like the Q605/P475. I put a full '040 in it and it runs NetBSD pretty well.

Thank you for the informative replies! Guess I'll go HDD hunting over the next few days and if nothing satisfactory comes up I'll order a SCSI2SD.
