I ran diagnostics on the drive using an Atola. I need a donar PCB and
maybe a head stack replacement as well. After some research it
appears that many of the new Hitachi drives store adaptives and other
information in the NVRAM stored on the PCB which will need to be moved
from the original PCB to the donar.
I'm not sure how to identify the NVRAM chip. Research I've come
across says the NVRAM chip is an 8-post chip and may be the U3 or U6
chip. Anothers say its the U5. Can someone identify and tell me how
they identified the NVRAM Chip on my PCB?
