MyBook Studio LX/Repeated "Disk Not Ejected Properly" Error Messages

Well, it appears to have been a bad drive.  WD sent me a replacement and that didn’t work so they sent me another.  I hooked it up and right away, a message popped up and said there’s a firmware update available.  So I proceeded with the update and the update failed…killing the drive.  So this time WD sends me a different model all together and after about a week, so far so good. =)  I hope it stays that way.
