Also, people from the general public don't know how to write random bits to a drive. Deleting files doesn't actually wipe the information, it just marks the space as available on the OS. Repair agents could still take an image of the drive and recover many of those secret documents.
It should be standard procedure in the repair world to hand the hard drive to the user to take home and keep only the PC for servicing.
- fencepost 5y agoBe aware that this can be completely different between HDDs ("spinning rust") and SSDs. HDDs don't get data cleared until it's explicitly overwritten, SSDs with OSes that support TRIM shouldn't have a lot of stray data left behind. Also when wiping SSDs get something like Parted Magic (since at least 2018 likely earlier) that can properly erase SSDs. DBAN is NOT appropriate for SSDs in any way - extra wear from the writes, and wear leveling means you have zero idea where they're actually going.
