This tests and verifies that every 'bit' on the selected partition can be successfully written to and retrieved. This level will read, write, and invert every sector twice of the selected partition(s) psychical surface. It tests and verifies every sector on the partition(s). This level will read and write every sector of the selected partition(s) psychical surface, mainly exercising the hard drive. Spinrite will then attempt to recover unreadable partition data using the built-in advanced recovery technology. This level will read every sector of the selected partition(s) psychical surface looking for unreadable data. This level will read every sector of the selected partition(s) psychical surface looking for areas that appear to be healthily but could fail in the future. SpinRite has five ( 5) levels of operation, each building on the previous level. Graphic Status Display screen from GRC SpinRite SpinRite is a self-contained program that runs on top of a version of FreeDOS ( Free Disk Operating System). SpinRite includes a feature called DynaStat that can reassemble missing data from bad sectors. SpinRite is a magnetic storage data recovery, repair, and maintenance program and works only on HDDs ( Hard Disk Drive) and not SSD's ( Solid State Drive). But when I need to check the hardware inside a hard drive, I will use SpinRite from Gibson Research Corporation. When it comes to maintaining a hard drive, running a disk check will usually find any software-related issues.
