Download DRevitalize
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 signals around the physically damaged area.
The surface of almost any drive can be repaired with this tool (even hard drives that were dropped down or exposed to strong electromagnetic fields). Please be aware that the DOS version of Drevitalize my not run on some desktop PCs with incompatible Intel chipsets.
Please check if the DOS demo is working in case a DOS HDD diagnostic program.
DRevitalize will only scan the drive for bad and slow sectors. It will not try to repair nor modify any data stored on the drive. Very useful when You have extremely valuable data on the drive and just need to test from time to time if everything with the drive is OK.
Drevitalize can also scan the drive using the standard read procedure (which was the only option in DRevitalize 2.30 and earlier). It will try to repair any bad sectors it encounters or refresh any slow sectors if the user specified such action in options. The default refresh slow sectors value is 150ms for multi-sector and 20ms for single sector scan mode but the user can alter this value.
The program is packed with a SMART self-test. Off-line mode tests execute in the background. Captive tests execute in the foreground and user needs to wait until they finish. Current drive status from offline data collection is displayed on the bottom of the page.
Self-test status and progress is also displayed on the bottom of the page and is updated periodically every 60 seconds if run in offline mode.
