: By repeatedly testing and analyzing "bad" sectors, SpinRite can often recover data that the operating system has given up on. Prevent Drive Failure

This is the headline feature. Previous versions couldn't understand the translation layer of SSDs. v6.1 introduces a specialized mode for Solid State Drives. It works by performing read-refresh-read cycles. It reads the data, checks it, and if the drive’s internal error correction is working overtime, it forces a "refresh" of that data. This prevents "bit rot" and revitalizes the drive's performance without the heavy wear of a traditional write-erase cycle.

You have a 2015 laptop that takes 10 minutes to boot. SpinRite v6.1 runs a "Level 3" scan (full surface test with refresh). It finds 80 "pending bad sectors." After the refresh, the drive relocates them. You run CHKDSK, and the file system is repaired. The laptop no longer freezes. You just bought another 2 years of life.
