  1. power issue with you psu try to use another psu this one could be short inside and if it still under warranty ask for rma
  2. I would bet it's the hard drive itself. try another one.
  3. Also, if you have an ohm meter..... You can see if that red lead is grounded.
  4. also check the screws you used to put the hard drive into the case if there too long you may have drilled into the hard drive pcb.
  5. thnx for ur rply
    its d power cable which was creating the problem d new 1 working fine........
  6. i would keep a eye on this the cable did not burn for nothing

    gud 2 hear was d cable causing d prob

    *sigh*
  8. I doubt that the cable was the problem. Instead it sounds like the drive has a shorted TVS protection diode near the SATA power connector. Repeatedly blasting this short circuit has probably opened up the short. Now your drive has no overvoltage protection, so the next time your PSU misbehaves will be fatal to your data.
