PCB for the HDN721010ALE604 drive

I am looking for a PCB for the HDN721010ALE604 drive, I have PCB no. 006-0A90561.

Due to the failure of the computer’s power supply, the zener diode responsible for the power supply was damaged.

There are several PCBs in your store. Which one should I buy?

Hitachi PCB 006-0A90561 is your donor PCB.

When you get this PCB, you need to move your original PCB’s BIOS to the replacement PCB. The 8pins (4 pins on each sides) with 25P05VP、25P10VP、25F512、25F1024、25F1024AN、SST25VF512、SST25VF010, etc. are the BIOS.
