Abstract

A method of securely deleting data from a data storage device is described. The method includes the steps of receiving a secure delete command to securely delete a file. A data block of the file to securely delete is identified. A pointer to the data block is stored in a deletion buffer. It is then determined whether the secure delete command has a highest priority over other data storage device commands. In response to the secure delete command having the highest priority, the secure delete command to the data block is performed.
