The subject application is directed to a system and method for the secure and correct deletion of data files from a data storage that bypasses the file system of an operating system. A secure erase service receives a request from a system interceptor, which has intercepted a system call from an application. The interceptor component communicates with the secure erase service via an interprocess communication module. The erase service receives the erase request from the communication module and communicates the erase request to a secure erase library. Using the file information within the secure erase request, the secure erase library queries the file system of the data storage device to determine the location of data blocks containing the data for deletion. Upon locating the data blocks, the secure erase library then instructs the device driver, via a virtual file system, to overwrite the data blocks a predetermined number of times.
