this HDD.
Modules operation read then error is servo.
But sa region change in rom. Then restart HDD. Drd DSC ready. Loader load. Sa region change in ram. Then all modules read and write ok. Smart clear reli list clear etc.
Head test read and write ok. All modules check all crc is ok in modules. No error in modules. Old rom write. Then tick tick tick.

Pls tell me how to solve this issue.
Data is important

Probably some modules are not original.

Make a hotswap donor and see if it behaves the same way. If it is - some modules are not original, if it isn't then make a hotswap and image the drive

That was my first thought, then I though a little more and realized that this drive has only one head

Hot swap same donor but tik tik tik.
Head map only 1 head.
