Bought this for my PS3 and had nothing but problems. My PS3 would crash alot and freeze for no reason all the time, and things like Play TV would skip when viewing recordings - never understood what the problem was and assumed it was a software problem. Reinstalling things and using the service recovery menu never helped. Would constantly get corrupted data on the drive every time it crashed. Eventually things stopped working completely and the PS3 couldn't recover from it. It got to the stage when I couldn't even format the drive using the PS3.
I connected it up to a PC and discovered that the drive had bad sectors on it which were unrepairable and it was this which was causing all the problems. The warranty on this drive is a joke and is nowhere near long enough to cover you when this fails.
I ended up losing all the PS3 data on it and had to throw the drive as I couldn't RMA it - it failed just after the warranty period expired which is typical. WD know full well how long these drives last which is why they only give short warranties on this drive. I will never buy a WD drive again - absolute rubbish quality.
Recently bought a 640GB Samsung drive as a replacement and everything is so much faster - no crashing, skipping, freezing etc. my PS3 is now running like a different machine.
If you have this WD drive and your PS3 is giving you problems - try connecting it to a PC and testing it using WD's diagnostic tools - It's probably faulty like mine was.
