Certain applications managing highly sensitive data require the ability to erase all data from a disk, rapidly and without possibility of retrieval as a last resort. Typical 'disk shredding' utilities attempt to overwrite the data to render it beyond recoverability.

Unfortunately, technology is available today to recover data from hard disk drives and even DRAM-based (volatile) SSDs even after shredding because of traces left from the effects of hysteresis. Erasing disk data beyond recovery requires that each storage element be cycled repeatedly five or six times, which takes a considerable amount of time. As a result, BiTMICRO^® developed and patented securErase^®, a firmware utility that erases all traces of data (except wear leveling statistical data) on each block of non-volatile memory efficiently and effectively. securErase^® is fully compliant with the remanence security requirements of the U.S. DoD, NSA, Air Force, Army and Navy.

When used in combination with PowerGuard^® II Erase mode, securErase^® is executed as soon as the system powers down and automatically resumes the erase procedure upon power up. On a disk with PowerGuard^® III in Standby mode, securErase^® may be executed by either depressing the external push button or by toggling the 3-way mode select switch from Standby Mode to Erase Mode. If for any reason the erase process fails to complete, securErase^® automatically resumes the erase procedure upon power up.

The standard erase facility (via a SCSI/IDE erase command) is provided in all BiTMICRO^® Flash disks.
