DRevitalize is a program that repairs bad sectors (physical defects) on popular magnetic media (hard drives and also floppy drives to some extent) by generating a special sequence of high and low level signals around the physically damaged area. The surface of almost any drive can be repaired with this utility (even hard drives that were dropped down or exposed to strong electromagnetic fields). This DRevitalize 2.20 (Demo) has a time penalty after repairing a bad sector. Major improvement in speed and compatibility with Windows XP were introduced since the release of Drevitalize 1.0.
