Hello Everyone - A member of the Corvette Forum said this is the best Mac forum to be a part of, so here I am along with my Mac issue. Hope someone can help me out.

I have a Power Mac dual processor G4 500 Mystic that won't fire up. From what I can tell the power supply has failed, but that's another issue and story. I've heard the power supply for that computer is a rare and expensive part to replace, so I decided to pick up a single processor G4 400 (AGP Graphics Sawtooth) for just over $100. as a "get me by for now" replacement instead of having the 500 DP repaired.

The broken G4 500 DP has a single Western Digital 120 gb hard drive I put in it, with Panther & OS 9 installed. The new G4 400 has a 28 gb Quantum with a fresh install of Tiger from the previous owners. Since my 120 gb Western Digital from the broken Mac has all of my files, programs, settings etc. I'd like to take that Western Digital out of the dead dual G4 and install it as the primary drive to boot from in the new G4 400, replacing the 28 gb Quantum, so I could simply just pick up where I left off, but I'm not sure if the OS X 10.3 on that Western Digital somehow configured itself to run on the dual processors when originally installed, and if so what would happen if I suddenly booted it up in a single processor box. Would it automatically adapt to the single processor, freak out and not work properly or at all, or would it not even matter?

If running the Western Digital from the dead DP as the primary drive in the G4 400 is not going to work, I'd like to take that hard drive and install it as a second drive in the G4 400 so I can at least access and salvage my old files. Can someone point me towards the steps I'd need to take to configure the hardware and software to accept the Western Digital as an additional secondary drive?

Thanks!

yes it will work
been there, done that! many many times.......

just check to be sure you have the dual-connector IDE cable and the double-stacker HD mounting sled that came standard in both of those machines.

You may need to check the jumpers on the back of the hdd's....
set one "master" and the other as "slave". Once booted up, look at the start-up disk pref pane and select the hd you want to boot from going forward. You can leave both of them in there if you wanna

And BTW, OS X doesn't "configure" itself perse to run on dual processors. If more than one cpu is available, it will be utilized by OS and any apps that are multi-threaded, plain & simple.

I recently went from a DP Sawtooth to a SP QS and moved all 4 of my drives over notta problemo
Signatures are ugly. Bitchy women are ugly......YOU do the math :)
