Here's a simplified process:
1) Remove drive cover.
2) Install jig to protect heads.
3) Remove top head stack magnet.
4) Unscrew connector that connects head stack to the controller board.
5) Unscrew and remove head stack.
6) Repeat steps 1-5 for donor head stack.
7) Install and screw in donor head stack.
8) Screw in connector from donor head stack.
9) Reinstall top head stack magnet.
10) Remove jig.
11) Reinstall drive cover.
12) Connect drive to computer running specialized software.
13) Build head map and recover as much data as possible. Note: Head 0 is critical. No Head 0, no data recovery.
Don't buy those $10 PSU "specials". They fail, and they have taken whole computers with them.

My computer doubles as a space heater.

Windows 10? Only if you like forced, buggy updates and 24/7 telemetry.

Samsung = Seagate = Seatrash = Trashgate
Don't buy Seagate drives. Don't use Seagate drives. If you have any in service right now, make plans to replace them ASAP.

SMR = Slow Magnetic Recording
Avoid SMR, buy CMR drives instead. SMR is easily a 15+ year step BACKWARDS in HDD speed.

Permanently Retired Systems:
RIP Advantech UNO-3072LA (2008-2021) - Decommissioned and taken out of service permanently due to lack of software support for it. Not very likely to ever be recommissioned again.
