Replacing the board in HDD Fujitsu MJA2160BH. The disk is not identified. What to do after replacement?

Question

Hello!
There is a Fujitsu MJA2160BH HDD. Once untwisted, after which he banged his heads and ceased to be determined. Or not defined at all. After reading the Internet, I decided that the problem is with the electronics. The chip was heated - not successfully. Also, a chip with a couple of cases was blown off with a hair dryer (they are all there, not lost). I bought a board for him on AliExpress, the same as it was (212EE CA21350-B12X). With it, it starts up normally, does not knock with its heads, but is not detected. What else can be done? You just need to get the info out of it.

If the data is important, you should at least stop and stop breaking the disk
