my work recently dumped some hardware e -waste kinda of deal and they allowed us if we wanted any of it we could take I snagged a few 3.8tb Intel SSD D3-s4510 hdd but some of them have unknown issues. I am looking for any software to do more of a hdd repair like testing sectors and do fixes to make the drive healthier. open source or free would be nice but if it does the job im willing to spend a little money on it(its always good to have some HDD tools), thanks in advance!!
