Bad sector

close bad sectors and make the hard disk reusable.I think I need to add it to the glist, but I don't know how.

If your drive is working correctly, writing to bad sectors remaps them and adds them to the G-List, if thats not happening, your glist might be full and your drive is toast. What's your smart data?

Wanting to learn, do most HDDs' S.M.A.R.T. data report the possible maximum GList? I.E., I have two hybrids, one with 86 re-allocated, the other with 253+- re-allocated, I was wondering what the average total would be. I have already purchased their replacements, simply awaiting the next full backups.

It's changing according to brand and models.

If you Wana play with G list, you need DR tools

AFAICT, the SMART threshold for reallocated sectors is less than the capacity of the G-list. At least I am not aware of any HDD whose SMART data report otherwise. I don't know about SSDs, though.
