I replaced my external 1TB Hitachi drive less than 2 months ago due to lack of space with a WD 2TB EVDS drive that has just died. The drive has been running flawlessly since intallation and ran much cooler and quieter than the Hitachi. Needless to say, I bummed as I've got quite a bit of additional material on it that can't be recovered. At least I've got the older drive to throw back in until the RMA replacement shows up. I was watching a movie and the screen just froze. After the watchdog rebooted things the HR20 wouldn't come up (my internal drive failed several years ago). I tried several things w/o success and thought I might have found the culprit in a bad eSATA cable - but replacing with a known good cable didn't fix things. as soon as I put the Hitachi back in the dock the HR20 booted right up. The EVDS sounds like it's got a head dragging as there's a slight sandpaper sound when the drive starts spinning. Definitely not a bearing. I've already got an advanced RMA request in so hopefully a replacement won't take too long. To guarantee you are encouraged to ship the failed drive back within 30 days they hold out $215 against the CC. I'm curious how many others have had one of the EVDS drives fail?
