Restoration of module 190 on a western digital hard drive

Word of advice, DO NOT try anything on your own if the data is important, ESPECIALLY if the drive is dropped and there is hardware damage.

From what I'm able to find, module 190 is part of the translator module for WD hard drives. The translator is responsible for converting LBA addresses sent from the host to actual physical sector numbers on the drive, so the drive can find the sector and read the data.

The translator database is unique per device, copying from another device will not work because the sector mapping is different.

If it is a 5TB drive, it's very likely to be a SMR drive, so the sector to LBA translation relationship is dynamic and changes all the time like a SSD, therefore the recovery becomes even more chaotic with the translator module damaged, although I'm not sure if module 190 is responsible for this kind of dynamic mapping.

Forget about doing it on your own, a few thousand dollars is already cheaper than if you try to do it yourself because the tools capable of booting the HDD into service mode and allow extraction/loading of service area modules already costs $10k on average.
