The Customer attached the wrong power lead resulting in a burning smell coming from the drive and damaging the hard drive PCB. With the damage to the hard drive PCB no power was getting to the drive. In this situation sometimes the incorrect power to the drive can affect the head assembly stack, in this case the customer was very lucky this was not the case.
After Fixing the hard drive PCB we imaged a copy of the drive onto a new hard drive, called the customer and gave him the good news.
Time to call the customer, fully recovered.
