If try to change anything in P list , LBA would change . And data would be changed. More files would be destroy.
But if you want to repair HDD , I am doing it with MRT. But not one click solution. I am doing it manually .
MRT p list editor not good for this. Drive allways turning to nonrecognised disk. No model number, 0 GB , busy mode etc. I am using cut zone section. It's working perfect. But have to check zones manually.
I have repaired ver very bad disks turned % 100 health, no bad sector ))
