Newer Dell Business Models have a feature in their UEFI BIOS called Data Wipe. The Data Wipe will allow you to carry out a Secure Wipe of your Internal Drives without third-party utilities.
To begin, power down your Dell. Then power it up and press [F2] when you see the Dell Logo to get to the UEFI BIOS Setup.
If your UEFI BIOS doesn't look like below, then you may have a newer BIOS version. Please proceed to these update instructions for newer BIOS versions.
Press the [↓] arrow (or use your mouse pointer if available) until you get to Maintenance and then press [Enter].
Press the [↓] arrow until you get to Data Wipe and then press [Enter]. If you have an older system without Data Wipe, you'll need to use Parted Magic to perform a Secure Wipe.
Check Wipe on Next Boot:
Select OK to perform the Data Wipe – this will clear the data from all internal storage devices:
To proceed you will need to select No at the dialogue which asks Do you want to cancel this operation:
Now to the bottom right, select Exit:
The UEFI BIOS splash screen will display:
You’ll be taken to Dell Security Manager. Again it will ask you if you want to cancel, with the default setting set to cancel:
Use the [←] arrow to highlight Continue and press [Enter]
It will warn you one last time, with the default option being set to Cancel:
Press the [→] arrow and highlight [Erase] and then press [Enter]:
It will now start to erase the internal drives.
This will take a couple of minutes for a SSD and will take several hours for a HDD.
When it is done, it will tell you Data Wipe Completed Successfully. Press [OK].
If you get an unsupported error message, your drive may not support Data Wipe - Sanitize if it is an old (<2013) SSD. You will have to use Parted Magic to wipe the hard drive. However in this case the SSD is supported but Bitlocker has been enabled on this drive and encrypted it. Please contact Extension IT Helpdesk @ firstname.lastname@example.org for assistance if you experience errors during this process.
Your computer will now have no data on it. You can shut it down and label it for Surplus.
As always if you run into any issues please contact the Extension IT Helpdesk at email@example.com.
