I have the same issue with a WD 640 GB drive in 2 out of three MBPs.
Unit 1: 640 GB drive stalls, Sound quit after 1 day, Apple replaced MBP
Unit 2: 640 GB drive works great but sound has high pitched squeal, Apple replaced MBP
Unit 3: 250 GB stock drive works no problem, 640 GB drive stalls, Argggggg
In all three cases I have went through all the usual support steps, safe mode, PRAM reset, Reinstall....

When you installed the 640 GB HD where was it before. Was it new and did you install the system with it inside the MacBook Pro 15'. If it was not new what machine did you take it out of?

It was brand new from Ifixit
