Abstract
An on demand method of initializing a data storage medium, the method including the steps of: specifying a region of the data storage medium that is to be initialized in preparation for storing data in that region; setting up a table for keeping track of which portions of the region have been initialized; in response to receiving a request for accessing a specified location within the region, checking the table to determine whether the location to which access is being requested had been previously initialized; if the table indicates that the specified location has not been previously initialized, initializing that specified location within the data storage medium; and updating the table to indicate that the specified location within the data storage medium has been initialized.
