1.3 Instant Secure Erase / Secure Erase
This section provides conceptual information and instructions for using the Instant Secure Erase (ISE) or
Secure Erase (SE) features included with Western Digital drives.
Data Erasure Options
Western Digital provides several options for securely erasing data from its drives. The appropriate method
depends upon many factors, including the following:
• Erase Configuration (ISE or SE)
• Drive Type (HDD or SSD)
• Interface Type (SAS, SATA, or NVMe™ )
• Encryption (none, TCG, or FIPS)
For more information on the
specification, contact Western Digital technical support, or download the following whitepaper for details:

ISE / SE Overview
Instant Secure Erase (ISE) is Western Digital's implementation of the industry standard T10 (SAS)/T13
(SATA)
sanitize
data from Western Digital drives.
The command supports three options:
sanitize
1. Crypto Scramble (SATA) / Crypto Erase (SAS) : deletes the encryption key of a self-encrypting drive.
2. Overwrite (HDDs) : overwrites the data on the drive with a supplied value.
3. Block Erase (SSDs) : electrically erases each storage element by modifying their voltage levels.
Secure Erase (SE) is a subset of ISE, where the Crypto Scramble / Erase option has been disabled, allowing
only the Overwrite or Block Erase options.
Requirements
To perform secure deletion, the following versions are the minimal recommended/supported utilities for
each drive interface required on the host. For other versions, please verify the arguments/parameters in the
appropriate man pages.
• SAS : sg_sanitize version 1.00 20151219 (included in sg3_utils 1.42
• SATA : hdparm version 9.58
Erase Methods
The following methods cover all erasure options and storage technologies for Western Digital drives.
For more information on the
specification.
Note: If a RAID adapter or software is in use, remove the drives from a RAID set before erasure.
2. For details on how to use the sg3_utils v1.42 utility, visit
command for specific drive models, please see the drive model's
sanitize
command, allowing users to instantly erase both user-accessible data and hidden user
command for specific drive models, please see the drive model's
sanitize
