If there was a killer reason to upgrade from v6.0, this is it. For years, a catastrophic bug existed in the BIOS of specific motherboards (dubbed the "Roger Anomaly"). When SpinRite 6.0 tried to write data to a drive, the bug could cause a "data shift," corrupting the sector written.
The Ultimate Guide to SpinRite v6.1: Data Recovery and Drive Maintenance spinrite v6.1
In v6.0, Level 4 was disabled due to architectural changes. This is the most powerful recovery mode for drives that are mechanically sound but have widespread magnetic decay. It writes a series of patterns (all ones, all zeros, alternating) to force the drive’s read/write head and platters to reorient magnetic domains. After the test, it restores your original data.

While v6.0 could occasionally "see" an SSD through BIOS emulation, v6.1 is built for them. It includes native support for NVMe drives, allowing it to perform data "refreshing." Even though SSDs don’t have magnetic platters, their electrons can "leak" over time (cell charge drift). SpinRite v6.1 reads and rewrites these cells to ensure the data remains "crisp" and readable by the controller. 3. Modern Hardware Compatibility The Ultimate Guide to SpinRite v6
