I have an Amiga 500 with an A590 HD chassy. On it is the original Western
Digital 20 meg IDE (cough, gag.. but hadda come with it). I was given
for christmas by a good friend a Seagate 40meg SCSI NiceAndFast drive.
I grabbed an old IBM power supply, and a SCSI ribbon cable, opened my
a590 and 'tached her up. Works beautifully, and reads *extremely* fast.
Makes my disk-anim works acutally ANIMATE.
Anyway, the problem: When I have both drives up and running at the same
time, some CPU intensive programs *CRASH* badly, with a Guru 00000003,
namely Addressing Error. I know it happens when I attach the second drive,
due to I replicated the crash, cured, it, and crashed again, as I attached,
removed, and attached the drive.
Tell me: does having BOTH drives working off the INTERNAL A590 drive
connectors (instead of having the SCSI on the *external* 25pin) draw more
voltage, or cause any other thing that would make my 500 get "Addressing
Errors" and crash while in mid-render? (Specific package: Turbo Silver.)
And, if it does: (1) how to cure it? (2) can you *GET* a cable for that
25pin to the pinrack on the back of the SCSI?... and (3) does having an
external supply that isn't grounded together with the 500 hurt?
