ATATool

ATATool is freeware software that is used to display and modify ATA disk information from a Microsoft Windows environment.[1] The software is typically used to manage host protected area (HPA) and device configuration overlay (DCO) features and is broadly similar to the hdparm for Linux. Recent versions include support for DCO restore and freeze operations, HPA security (password) operations and simulated bad sectors.[2]

Data safety

Use of the ATATool can permanently change the disk configuration, may result in permanent data loss by making some sectors of the disk inaccessible. The tool should therefore be used with extreme care.[3]
