When I had my formatter replaced because of the Hitachi HD failing, the 'new' formatter had an older model Hitachi drive on it - back to the tried and tested, I suppose. It hasn't let me down since, though I also got that bad fan in the power supply that John had - the whole of the electronics (minus formatter) had to replaced, under warranty, thankfully. I look at my Z now and am reminded of the old story about the axe. Would I own a large-format printer without a warranty? Not on your nellie.
