SpinRite
SpinRite is a computer software program for scanning magnetic data storage devices such as hard disks, recovering data from them and refreshing their surfaces. The first version was released in 1987. Version 6.0, still current , was released in 2004.〔(【引用サイトリンク】 url=http://www.grc.com/sr/spinrite.htm )〕 SpinRite is run from a bootable medium (floppy disc, optical disc, bootable external storage device such as a USB stick) on a PC-compatible computer. Spinrite uses its own operating system and ignores any boot loader or file system structure that may be on the drive being examined.
== History ==
SpinRite was originally written as a hard drive interleave tool. At the time SpinRite was designed, hard drives often had a defect list printed on the nameplate, listing known bad sectors discovered at the factory. In changing the drive's interleave, SpinRite needed to be able to remap these physical defects into different logical sectors. SpinRite therefore gained its data recovery and testing capabilities as a side-effect of its original purpose. Gibson states that today, drive interleave is no longer an issue, but the data recovery features of the tool proved to be so useful that it evolved into the data recovery tool that it is today.
