These commands only do harm. Especially to data recovery.
As well as recalculating the translator without a backup of system files.
And it is impossible to restore erased P-list records. They are unique for each disk.
For your level of knowledge - listen to the pepe:
"without knowhow you better outsource it..."

Ok. Thanks SWM Sir. I will return back this hdd to customer.
Case close.

00000000   00 00 00 00 00 00 9D 8F  00 00 00 00 00 00 00 00

first you wrote you can't access sector, to me this means no LBA access. You didn't write wether capacity is OK. Now you write partial access, it is confusing.
If you have partial access, what's the last lba you can read?

Partial access means drive is able to read user area up to a specific LBA. You say all sectors are inaccessible, ie this is not a partial access problem. Without tools you will likely cause more harm than good, plugging defective disks under windows is a very bad idea anyway.
