      Hi Guys,

      Thanks for the heads up on the voice coils..
      I checked my PWM frequency and it was running at
      my problem was I was running waaayyy to much voltage
      through the voice coil.. (ermm... Im embarrassed to
      say, I was messing around at 12 - 24v, which I
      cottoned onto when smoke and general flames errupted
      from the coil!)
      Anyway, knocked it down to 5v, grabbed another dead
      hard drive away I went!!

      Well, until I killed my PIC programmer, that is.. So I
      need to replace parts on that..
      Oh well, Ill have to wait till tomorrow.
      Public Holidays are great.. Except all the shops are

      Thanks again,
