Data recovery and disk repair questions and discussions related to old-fashioned SATA, SAS, SCSI, IDE, MFM hard drives - any type of storage device that has moving parts

I recently experienced an overvoltage event that wiped out three hard drives (two conventional HDDs {WD} and one SSD) The SSD contained the OS and I got a warranty replacement for it. I am in the process of trying to recover the data off of the conventional HDDs. After googling around, I found that the tvs diode maybe bad. I tested two diodes (D3 and D4). I found D3 to be bad and the resistor before it (R67) to be bad too. I clipped the diode and the resistor and place a paperclip over the old resistor. I am still having a hard time getting the drive to spin up.
Any help is greatly appreciated!

The preamp is probably dead.
