" Have a look at this:
PowerBook G4 (15-inch 1.67/1.5GHz) Memory Slot Repair Extension Program

Finally Apple have done something about this issue. I had this problem in the summer of last year and got it fixed under warranty. Still its good to know that it will be fixed free of charge should it ever occur on my computer again...

" Just installed a new Raptor 150 in my G5 2.7 DP. It took me a while to get it going since I was cloning it over from a Raptor 74, you know the usual voodoo, zero out the drive 1st (even though it's new) (normally you don't need to do that unless you suspect it has bad sectors) and then clone it over and then run permissions, Disk Warrior, etc..
Anyways, I'm happy to report that it works in a Mac and it's a speed demon. I'm not big on benchmarks but I can tell you that it destroyed the old "74" and it leaves others on another planet.
Another big plus for G5's is that this drive is MUCH QUIETER.
Take care, Niko
P.S. I can send the actual benchmarks if anyone's interested. "

At first I said it was good to hear the new Raptor dosn't have the G5 onboard SATA issues reported with the WD4000KD (400GB/7200rpm) drive, but Niko wrote on Jan 25th that he later saw problems with the new Raptor:

"Subject: Raptor 150 (Bad News) Follow up...
Hi Mike,
Just wanted to report a follow up...
It worked great the first night when I reported the install to you, it wasn't having any of the symptoms that some of the other WD's people were reporting about. I moved a huge chunk of data onto and then back to another drive and it worked only the first couple of times. The next evening spelled disaster...

It was having the same issues that the others were having only worse, it was corrupting data and it wreaked havoc on some system files. I tried to repair permissions and then ran some other utilities only to have the system lock up again. I checked the jumpers and tried everything that other people posted and then checked WD's website as well with no luck. I finally decided to boot off a Firmtek 1/V4 card and it finally worked. Now I have to re-clone the drive from my original drive and call it a day.

The only thing that doesn't work is the Apple Hardware Test, it won't boot now, it reports some type of RAM kernel error and refuses to start the test. Oh well, I guess it's a small price to pay for booting the beast off another controller card.
It seems to be booting just as fast off the Firmtek card as it did with the on-board SATA, takes about 18 seconds. (Normally booting from PCI cards takes a bit longer.)
Take care, Niko "

You can find full owner reports (latest shown first) by searching the database by drive/brand/interface/mac models (the latest reports are shown first in searches). For guides to installing CD/CDRW/DVD drives or Hard drives in many mac models, see the IDE Articles page. The Firewire articles page also has guides on case kits, installing drives, etc.
If you've added a IDE, SCSI, Firewire or USB hard drive, CDRW, tape drive, etc. make sure you add a report to the database. (If you post an updated entry - make sure you use the same name, etc. as you did before so I can find your past entry. Thanks.)
(Incomplete entries are deleted. Do not post questions in the database, it's for drive reports not questions on what drive to buy - for that try searching the database for reports from owners of your mac model on the drive type/brand/interface, etc. you're interested in.)
