Either that or you've left both rubber spacers in between the PCB and the head stack connector, so they don't connect.

The pre-amp "6c" identifier is not compatible. Simple as that ;o)

With Seagate having over 300 seperate part numbers for OEMS I am not surprised

Dell may require a specific pre-amp to go with a media combination.. IBM may require something else... Each OEM requests a certain spec and Seagate will mix n match components for best yield <> reliability for each vendor

Take pics of the little PCB's inside the drive (that connects the head stack to the PCB, through the drive).

A= Agere example (TrueStore PA7800 EOL)


Apples & Pears
Chalk & Cheese
