WD 1TB Drive won't work internally, works externally; late 2007 mac pro

Hi,

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

When you first installed it, in Dock station or internally, did you get a dialogue box asking if you want *Eject, Ignore or Initialize?*

Any trouble? you say that trying to zero out data there is.
Click on "WDC...." in Disk Utility, secure erase the drive and opt for zero or 7-way write.

I just bought a Docking device, but it has esata and usb, only used esata so far and accepts a "raw" drive. Very convenient and $35.

If possible I would install and run Windows and use WD utility.

When I first dropped it into the dock, I believe I chose "Ignore" and my computer actually kernal panicked. I'm not sure why that happened, but after it started back up I tried again, chose initialize, and I forget exactly what initialize did, but it made the drive usable in the dock.

Um, I attempted to do a secure erase with the zero out option, and that's when it sat for 30 minutes with the status "preparing to zero data"

I've been in Windows all day now using the WD diagnostic tool. the quick test and long test both showed a PASS, now I'm attempting to zero data using the tool and it was working fine for 3 hours, until with 5 minutes and 50 million sectors left, it has started to go backwards, slowly increasing the time remaining, and making very tiny incremental steps forward in the sector count.

What I'm really looking for is any insight on whether this seems to be a Drive problem or whether the mac pro that I've got doesn't support this drive. The fact that it works perfectly fine in a Dock would seem to indicate the drive is fine. But I can't find official literature that says my mac won't support 1TB Drives, and every comment I've seen from people on various forums indicates that a) a mac pro should support any SATA drive, the capacity shouldn't matter, and b) this specific drive has worked in mac pros before.

Anyone have insights?

I've had two WD drives in the last year with bad sectors or just erratic I/O pattern. Yours though I'd RMA to WD.

What I do with 1TB is format into 4 NTFS partitions, and each of those one by one do long format in Windows, which takes an hour maybe? not sure and it was running in background.

With 750GB drive I did have to use all the extended tests and zero the drive but afterward it was okay, maybe 3 hrs? so 4 hrs sounds possible.

Your Mac supports 1.9TB volumes and larger - no problem.

This is the dock I bought and has been fine:

This is what my bum 750 looked like, and that is even AFTER running DU Zero-all AND Intech Speedtools to map out weak sectors and do media test:
