Why Wipe Hard Drives from BIOS

Generally speaking, you can erase data by formatting or wiping a hard drive while running the computer. However, if you are trying to wipe a system drive, you need to wipe it from BIOS because it can’t be done while the drive is in use.


BIOS is located on an erasable, programmable, read-only chip. It can be used to check if hardware items including the central processing unit, dedicated graphics card, as well as random access memory and hard drives are operational on startup.

You are also required to wipe or erase a hard drive from BIOS when you are going to reinstall Windows or clean install Windows on the device. To do so, you are required to format the system partition but this can’t be conducted within Windows.

You still have to wipe the hard disk in BIOS. Before starting the process, you’d better back up the data if there’s any important. Otherwise, you will experience data loss.
