SpinRite
SpinRite is a piece of data recovery software written by Steve Gibson of dubious Security Now fame. Anyone familiar with the matter knows how much Gibson likes to boast about SpinRite, how it is a complicated piece of software writted in pure Assembly language, how it’s polished and thoroughly tested on a variety of obscure hardware to achieve perfection at every release, and how its data-recovery algorithms are based on intricate physics of modern disks to ensure the recovery of every bit of data that could possibly be recovered. The data recovery ability “which far exceeds any other known utility” is the main selling pitch there.
