Please return the drive for evaluation. If it's repairable, we'll repair it for free including free return shipping. If it's not repairable, we'll give you the bad news. Include a note describing the problem.
For drives under warrantee, we have a 'one time only, stuff happens' deal. Include a full, written confession on what dumb thing you did to blow up the drive (ran over it with a forklift, applied 480VAC, etc) and we will send a brand new one for free (only once).
I think I can type this in my sleep by now.:-)
