My power supply cable for the HDD of my Indy melted just 10 minutes ago.
Luckily I see no damage to my SGI.

HDD1 is 80 PIN HDD with a scsi converter to 50 pin - my current drive
HDD2 some unknown 50 scsi - a new drive I wanted to test

So I decided to add HDD2 while HDD1 is attached (not on a running system) and upon powering up my Indy the cable connecting to HDD1 (not the HDD2 - the new one) melted. The plastic covering is almost gone. I tried the old configuration only with HDD1 and now everything is OK. 

I do not understand. The Indy does not support 2 HDDs on the internal scsi cable?
Or it is the 80 to 50 pin scsi converter (as this cable melted) that did something wrong?
A second HDD should be attached only on the external scsi bus?
Or just HDD2 was bad? But when I attached just HDD2 to the Indy before it was OK. No melting at least.
Could it be the power supply not supporting the load?

It was a short circuit I think. The power supply did not start, but it was slowly ticking.
