Method and apparatus for purging information from a storage medium such as a floppy disk or a hard disk drive. A region to be purged is defined such as a storage medium or a portion of a storage medium. A purge is performed of the defined purge region by overwriting all locations in the defined purge area with a character, the complement of the character, and a random character. A number of wipe iterations may be defined where the performing is repeating until the defined number of wipe iterations is attained. The purge may also be verified by reading all locations in the purge region, and checking for inconsistent data and remaining original data by comparing all read locations with the last character written during the purge.
