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)
•Encryption (none, TCG, or FIPS)
For more information on the sanitize command for specific drive models, please see the drive model's
specification, contact Western Digital technical support, or download the following whitepaper for details:
https://documents.westerndigital.com/content/dam/doc-library/en_us/assets/public/western-digital/
collateral/tech-brief/tech-brief-instant-secure-erase....
ISE / SE Overview
Instant Secure Erase (ISE) is Western Digital’s implementation of the industry standard T10 (SAS)/T13 (SATA)
sanitize command, allowing users to instantly erase both user-accesible data and hidden user data from
Western Digital drives.
The sanitize command supports three options:
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 sanitize command for specific drive models, please see the drive model's
specification.
Note: If a RAID adapter or software is in use, remove the drives from a RAID set before erasure.
* For details on how to use the sg3_utils v1.42 utility, visit http://sg.danny.cz/

1.3 Instant Secure Erase / Secure Erase
Note: If a drive is encrypted (TCG or FIPS), unlock the drive before executing any sanitize
commands.
Note: In the following commands, replace the generic reference of <dev> with the specific
device reference appropriate for your operating system (i.e. sgX for Linux, SCSIX:X,X,X for
Windows).
SAS
Note: In the following sg_sanitize commands, the --quick option starts the deletion
immediately. If the --quick option is not specified, the drive's inquiry response strings are
printed in case the wrong device has been specified, and the user is given 15 seconds to
reconsider whether they wish to erase all the data on the drive.

Powering Down the Enclosure
Step 1 : At the rear of the enclosure, locate the power cable connected to each PSU:
Step 2 : Detach the cable retention clip from the power cable:
Step 3 : Remove the power cable by pulling its plug away from the receptacle on the PSU.
Caution: To reduce the potential for damaging equipment, do not jerk the cable
out of the PSU.
Step 4 : Repeat these steps to remove the remaining power cable.
Removing the SAS Cables
Step 5 : At the rear of the enclosure, locate the three (3) HD Mini-SAS cables attached to each ESM:
* 2 people required for lifting enclosure; only 1 required for disassembly

1.4 2U24 Flash Storage Platform Disassembly
Step 6 : If the HD Mini-SAS cables will be reinstalled at a later time, ensure each is labeled or removed in
an organized manner such that it can be returned to the same port from which it was removed.
Step 7 : To remove an HD Mini-SAS cable, pull on the blue tab extending from beneath the connector.
This will free the cable from the port.
Caution: To reduce the potential for damaging equipment, do not jerk the cable
out of the ESM.
Step 8 : Repeat these steps to remove the remaining HD Mini-SAS cables.
Removing the Drives
Step 9 : At the front of the enclosure, locate the twenty-four (24) drives.
Step 10 : If the drives will be reinstalled at a later time, ensure each is labeled or removed in an organized
manner such that it can be returned to the same bay from which it was removed.
Step 11 : To remove a drive assembly, press the release button to unlatch the drive carrier from the
enclosure.
The carrier's handle should extend out of the enclosure:
Step 12 : Grasp the handle and pull the drive carrier out of the enclosure with even pressure:

Step 13 : Repeat these steps to remove the remaining drives from the enclosure. Store each drive
assembly in an ESD-safe environment. Do not stack them on top of one another.
Disassembling Drive Assemblies
Step 14 : Lay a drive assembly (drive & carrier) on its side.
Step 15 : Using a #2 Phillips screwdriver, remove the four (4) M3 6mm screws from the edges of the drive
carrier:
Step 16 : Pull the drive upward to remove it from the carrier:
