The hard disk controller (hard drive scarf) has died. Will a replacement from a similar one help?

Question

Hard disks

The hard drive WD3200AAJS died. Ha scarf very hot chipik. Apparently - shorty.
Will transplanting the controller from a similar disk help to pull out the data?

Answer 1

If you mean to transfer the whole board from a similar disk, then no. All disks leave the assembly line with troubles that are stored in memory. That is, each disc is unique. If the controller is live, you can transfer it, that is, solder it, only to the working board. I did this more than once when there were two identical disks - one with dead pancakes, the second with a dead board.

Answer 2

Since you ask a similar question and put it in this way, self-repair will definitely not help you. Contact the experts.

Answer 3

Will transplanting the controller from a similar disk help to pull out the data?

If by "controller" you mean the entire board, then no. But there is still a chance. The fact is that infa, specifically tied to this disk, is partially stored on the pancakes themselves, in the service area, and partially in the controller. This means that when transplanting, you will have to solder from the old controller to a new one, either a ROM with this information, or the entire MK, in whose permanent memory it can be.

the chip gets very hot.

If this "chip" is exactly the ROM or MK that needs to be transplanted, then there is no chance.
