The present invention discloses a method for protecting hard disk data in a virtual context, which comprises: a virtual machine monitor acquires information on a hard disk storage unit needed to be protected as instructed by a user; the virtual machine monitor acquires information on a hard disk storage unit to be accessed by a hard disk read-write command from operating system based on the read-write command; the virtual machine monitor judges whether the hard disk storage unit to be accessed by the read-write command is the hard disk storage unit needed to be protected based on the information on the hard disk storage unit to be accessed by the read-write command as well as the information on the hard disk storage unit needed to be protected as instructed by the user; and the hard disk read-write command is processed based on the result of the judgment. According to the present invention, the VMM intercepts the hard disk storage unit involved in the hard disk read-write command and returns to the operating system the information indicating inoperability or error data if the hard disk storage unit is the hard disk storage unit needed to be protected as instructed by the user. Therefore data is secured effectively to avoid infection from virus or attacks from hackers.
