Hello,
Yesterday my Seagate HDD died. Now BIOS isn't recognizing it, and data is not accessible. I think i must replace the heads to get it working again, but would like to hear what do you think.
I had read the serial port output with TTL USB<-> Serial converter and it is:

When i connect power cable, it spin-up, click few times then spin-down.
I have another disk the same model as this one. Also i had read the serial output from the PCB without connecting to the disk, and it seems to return the same output, would it be something related to the PCB?
I have no access to a clean room, but looking in youtube, i found an possible alternative to do heads swap, what do you think about this video?
https://www.youtube.com/watch?v=xPEa0Wc9iUcIf i do swap the heads, i will need to adjust any setting in the room, or probably it will run fine?
As i stated before, i have another disk that matches exactly the same model as this one, what about replacing both PCB(keeping the ROM from original disk) and heads? or should i try replacing only PCB before trying heads?
I always liked Maxtor(now Seagate) disks, but recently it's only disappointing me, my next disks will be WD. Yesterday something strange happened by here, 3 disks failed(2 recovered, 1 died), also a PSU from another PC died. thats weird that i have a double conversion, sinusoidal UPS, anyways, any tip about if would it be possible to recover that data?
thanks, and best regards

sorry, i forgot to attach photo from PCB :
