Abstract
A host-transparent, performance-unaffecting, self-contained write authentication test (SWAT) is implemented in a disc drive to utilize periods of disc drive inactivity to self-verify data written to a disc in a disc drive and further record in the Self Monitoring Analysis & Reporting Technology (SMART) feature of the disc drive, various resultant metrics characterizing the operation of the disc drive during the data authentication. The disc drive maintains a list of recently received write commands, and after a period of inactivity from the host, optionally sorts and parses the list of recent write commands, executes reads from the disc of the data recently written, and records operational parameters characterizing failed data verification during the reads in the SMART feature.
