I have had my 522 for about three months now. Yesterday when we got up we had to allow the dvr to delete all of our programming because of diagnostics or something. This morning when I got up it was running diagnostics on the hard drive and said it should be done in 45 minutes, but the minutes elapsed said 154!! I think I heard the hard drive making a clicking noise like a computers hard drive when it is stuck on a sector. Should I give dish a call and have them replace my dvr?
