WD 1TB Drive won't work internally, works externally; late 2007 mac pro
I have a 2x2.66 (quad core total) Mac Pro, purchased in late 2007. I just got a Western Digital 1TB HD, (WD1001FALS), and when I put it into any of the drive bays it is giving me a ton of issues, however, when I use an external USB dock to hook it up, the drive works fine.
When I use it internally, the first thing I've noticed is a slight clicking. It's not a r/w arm failure, and it doesn't ever stop spinning, but it clicks for a few seconds, sometimes stops, and clicks again. the clicking is not nearly as loud as a r/w arm failure. When I put the drive in the external dock it does not click like this at all.
Internally I have been able to recognize the drive both in disk utility, and briefly, in finder, although in general once I'm able to get my system started, both finder and disk utility have been incredibly slow and crashed multiple times. I've found that some times the system is slow to start up, and sits at the gray screen (prior to any apple or broken folder icon showing up) for a long time. At times holding ALT has prompted it to start up.
I've run verify disk on the drive twice. The first time it told me there were problems (didn't record what it was) and then disk utility stopped responding. The second time I ran verify it told me the drive was fine.
I attempted to erase the drive choosing Zero Out Data, which sat for nearly 30 minutes with the status "Preparing to zero data" before I stopped it.
Whenever it has shown up in disk utility, which it hasn't always, it usually shows up with the drive name and then the indented partition name, however the second line (indented) is grayed a bit.
Externally I've been able to read and write perfectly fine to this drive and experienced no problems at all.
I am not sure what is wrong, whether it's the drive, the firmware, or the mac pro. I can't find literature that says the mac pro I've got doesn't support drives of this size, but some people seem to think it might be the case.
Here are my computer's specs:
Model Name: Mac Pro
Model Identifier: MacPro1,1
Processor Name: Dual-Core Intel Xeon
Processor Speed: 2.66 GHz
Number Of Processors: 2
Total Number Of Cores: 4
It was purchased in November of 2007.
Any help would be greatly appreciated!
Thanks,
Scott
