SpinRite is a computer software program for scanning magnetic data storage devices such as hard disks, recovering data from them and refreshing their surfaces. It is proprietary and commercial software written by Steve Gibson of Gibson Research Corporation. The first version was released in 1988. Version 6.0, still current as of February 2012, was released in 2004. SpinRite may be run from a bootable floppy disk, USB flash drive or CD-ROM on a PC-compatible computer, independent of the operating system installed on the host computer.
