Dell Data Wipe

Dell Data Wipe is a feature in Dell Enterprise Client BIOS that gives our customers the ability to invoke a data wipe of the internal storage devices in their system. This allows efficient erasure for repurpose or redeployment using industry-standard data wipe capabilities already supported by Dell storage devices.

Since customer data is a priority for Dell we designed this feature for maximum compatibility, and minimal potential for unintentional data erase.

• Supports internal storage devices only: SATA hard drive, SSD, and eMMC depending on the device types supported by the system.
• Uses industry standard approved methods for data wipe such as Secure Erase for SATA and Sanitize for eMMC.
• Only accessible by a physically present user. The user must be physically present until the drive wipe begins.
• All internal drives in the system are wiped, no option to wipe only certain storage devices.

The Data Wipe feature is invoked from within BIOS Setup. At the Dell splash screen press F2 to enter BIOS Setup.

Once in the BIOS Setup application, the user can select "Wipe on Next Boot" from the Security > Data Wipe option or Advanced > Maintenance to invoke data wipe for all internal drives after the reboot.

The BIOS asks for user confirmation twice before allowing the user to exit setup with the "Wipe on Next Boot" option selected to ensure that the user intends to erase all storage devices.

As an added safety measure, the BIOS will adjust the default selection for the final prompt to further enforce direct user acceptance of this operation.

Once the option is successfully selected and the prompts have been confirmed, the user exits BIOS Setup to force a reboot of the system and begin the data wipe process.

After the reboot, the BIOS once again prompts for several confirmations before sending the data wipe instructions to the customer storage devices.

The user can select to cancel the drive wipe procedure at either of these prompts, and the data wipe trigger will be reset. The process must be reinitiated from BIOS Setup to restart the erasing procedure, if wanted.

A successful erase procedure is reported by a green dialog and the "Data Wipe Completed Successfully" message. If there are any failures, they are presented instead of the success dialog: "Reboot the system and reinstall the OS".
