My WD 750GB (750AAKS) died on me a little while back. It just wouldn't spin up any more (yes, the data was backed up). The bearing on that thing was always a little too noisy for comfort. Hey, guess I know why... A week and a half ago, I looked up Western Digital's RMA procedures and booked the drive for a warranty replacement, following them exactly. I just had to give the drive, suitably packed, to their shipping company, Ceva, no charges, no paperwork to sign. You know those little cardboard boxes with the soft foam you get drives in when bought online? Keep them and the antistatic bags, too. Today, UPS delivers a brand new 1TB drive (WD1001FALS) !! So, I got great service and it didn't cost me a penny. Of course it works just fine and now I can raid it with my other WD1001FALS drive if I want to. Been buying WD for years and this is their first drive failure. Great warranty service. I'm glad that my faith in them was justified.
