Utility to Lock-Unlock your hard disk
-
Hi, Do you know locking/unlocking capability of your hard disk? If not, read following. Every hard disk has inbuilt controller, called ATA controller. ATA stands for Advanced Technology Attachment or AT Attachement. ATA is the standard protocol to interact with the hard disk. ATA protocol has several commands using which hard disk can be locked or unlocked. This lock is the hardware lock. Once hard disk is locked, you can't read/write from your hard disk, until unlocked. Once it is locked, all commands to hard disk will be aborted, except commands for unlocking and some special commands. Almost all modern hard disk support security feature. By default security feature is disabled. It needs to be enabled and then only hard disk can be locked/unlocked. Some older hard disk might not support this feature. I have created a utility, completely coded 'C' language, to lock/unlock hard disk. For more details and downloading this utility, visit Lock-Unlock Hard Disk[^] Thanks, Sandeep B. Vaniya
