Hello,
This issue has been destroying my brain.
I'm going to try to explain the issue in as much detail as I possibly can
I have two 15" Powerbook G4's, 1.67GHz, one has a Toshiba 80 GB hard drive (Powerbook 1), another one has a Toshiba 60 GB hard drive (Powerbook 2).
Powerbook 1: The super drive on the 80GB hard drive takes CD's/DVD's but does not eject them, or recognize them. In System Profiler the Disc Burning section says "No burning device was found. If you are using an external device please make sure that it is connected and powered properly". I cannot boot of this CD drive or anything.
Powerbook 2: Now the 60GB Powerbook works flawlessly, even though it has a non-oem Matshita DVD-RAM UJ-845S drive.
I had to take the 60GB hd out of Powerbook 2 and install it into Powerbook 1. The darnest thing happened, Powerbook 1's CD drive started working without a problem. Powerbook 2 is now with the 80GB hard drive and without a functional CD drive.
I put the 60GB HD back into Powerbook 2, and the CD drive started working again. I put the 60GB HD into Powerbook 1 and left put it together because it is fully functional.
Now I have the Powerbook 2 that still has problems with the cd drive.
I have tried using 2-3 other hard drives (they were from windows machines though), still no luck on getting the CD drive to work.
If I disconnect the 80GB Hard Drive, then I can boot from the CD drive. I just unplugged the internal hard drive, and attached another Powerbook (this one is 17"), and booted the 17" inch one into firewire mode, then started the Powerbook 2 and booted into the firewire HD.
Now I'm looking at the System Profiler, and I'm seeing the disc burner.
My conclusions to this issue:
It seems like all of the hard drives, except the 60GB one, can't seem to run along with the cd drive. This is not a motherboard or a CD drive problem, because both of the 15" computers can have everything working, depending on which hard drive is used.
I heard that these CD drives have an issue of being setup in Cable Select, instead of Master. I tried using different firmware (I had to plug up the drive to a PC laptop and flashed the firmware with D100 firmware http://forum.rpc1.org/dl_firmware.php?download_id=2094 )
Please help me, any suggestions will be greatly appreciated.
Thanks!
