SUMMARY: big disk in sparc 1+

From: Bill Morrow (

Only 2 of 11 respondents had problems adding large internal
drives to SS1/SS1+ machines.

I've ordered a 1.0 G drive, rated at 11.5 W power consumption. I will probably
remove the internal Quantum 105 drive and place it in another machine just to
be on the safe side, leaving only the 1GB drive internal. I also plan to watch
the internal heat buildup for awhile before and after. I'll re-summarize if
catastrophe hits :{

The FAQ says you shouldn't install a larger capacity drive
in a Sparcstation 1. Is this still true? I have a quote
from my Fujitsu supplier that their 520MB half height
draws 10 W, and their 1.0GB drive draws 11.5 W.

I have had two Quantum 105s, each rated at 10 W in this SS1+ for
about 4 years with no problems. Basic thermodynamics says
it shouldn't be a problem putting one of these larger drives
in place of one of the Quantums.
