- drive. The first pass writes zeros (00h), the second pass writes ones (FFh),
Multiple and the third pass writes a randomly selected constant value between 01h
Pass and FEh.
Secure The ATA Secure Erase command instructs the HDD to reset all available
Erase blocks to the erase state. How the erase state is implemented may vary
(SSD depending on the drive manufacturer (not necessarily 00h). This feature is
only) available for SSD destinations only.
Note: Overwrite wipes do not overwrite an HPA and/or DCO if present on the
destination drive.

Secure Erasing

Secure Erase completely deletes all data on a solid-state drive (SSD). This operation usually
takes less than ten seconds. The Secure Erase option displays in all TX1 settings but works only
on SSDs that support it.
The TX1 does not support Secure Erase on hard disk drives (HDD). Many manufacturers of
hard disk drives (HDD) claim they support Secure Erase but not all implement this feature
properly. A drive may be rendered permanently inoperable when this feature is improperly
implemented or if the command is interrupted.
Verification does not take place for Secure Erase wipes.
