@Vlad sorry, I'm n00b.
I asked you to help me with this disk, you said I must block FW booting, then overwrite module 02 with 802e. You said nothing about overlays etc. so now I'm asking a ton of questions.
As I said before - I don't know to much about HDDs, but I'm not an idiot, I can root phones, getting access to TV consoles etc if I have some tutorial. I'm also aware of the risk of bricking this HDD.
So, can you lead me by the hand like a small, blind child through the dark forest?

FW ver 15.2JT
Reported errors:
pins grounded:
uploading ID11: Ошибка чтения модуля ID11
uploading ID13: Ошибка считывания модуля ID13...
uploading ID1B: Ошибка считывания модуля ID1B...
I've found here uploaded locarno's Default dir with whole directory structure (Modules, Tracks...), but I think his 11.mod or 13.mod isn't compatible with my HDD, right?
