Power down your Dell and wait 10 seconds. WARNING: This Guide will instruct in the Secure Erasure of all Data on your systems Internal Drive. This Tool is available only on newer Business Models such as the Precision, XPS, OptiPlex and Latitude models built in 2017 or later which have an SMBIOS version of 3.0 or later (some systems with a SMBIOS version of 2.9 also possess Dell Data Wipe but have a different UEFI BIOS User Interface to this guide). Introductionĭell have followed our feedback and now have incorporated a Maintenance Tool in the UEFI BIOS which allows one to Securely Erase all Internal Drives. Third party programs or data recovery programs can still read the free space on the drive and restore the data, moreover malicious software can lie on this space and automatically reinfect your Operating System.Ī Secure Wipe on the other hand rewrites everything to 0, meaning all the data is wiped and such programs cannot recover the files and malicious software cannot survive. This means the data is still there, just that it cannot be read directly using the OS. When one formats a drive, they assign all the space on the drive as free space for use by the operating system. If you are confused between the difference between Format and Wipe, have a look at the schematic below. For older systems you can use Parted Magic instead. If your system is non-touch screen (or a Desktop) you might have a different style of UEFI BIOS setup see here.
The UEFI BIOS user interface shown below is for touch systems.
Dell Business models such as the OptiPlex, Latitude and Precision series that are manufactured in 2016 or later and have a UEFI BIOS that it SMBIOS Version 2.9 or later have the ability to use Dell Data Wipe which securely wipes all internal hard drives and can be launched from the UEFI BIOS setup.
