I RMAed one of my 36 gb raptors, and shipped it to WD on January 28th. It was part of a raid 0 array, and this single drive would randomly power cycle (in three completely different machines). I received a brand new 36 gb raptor today, manufactured on Feb 03, 2005. The entire process was pain-free with no BS involved. I just thought I'd share this for all those people thinking about buying some raptors.
