This video shows the process of a Seagate HDD controller board MCU chip swap for data recovery purposes. This is needed when you need to access data on HDD that had heads replaced, controller replaced or rom chip replaced. ROM is protected via signature and MCU checks and compares ROM signature to the one that was written to its maskROM during production. There is a way to read/bypass signature verification via software, but it is not working sometimes, based on FW/MCU/PCB revision. Thisbis the case when software didnnot work, so MCU had to be transplanted due to original controller failure beyond repairability. Newer hard drive models are becoming more complex to work with and its harder to recover. This increases the amount of resources needed for recovery thus increasing price.
