A technician has replaced a faulty 500 GB HDD with a 1 TB HDD in a laptop. However, after the replacement, the laptop is still detecting the new 1 TB HDD as the older 500 GB HDD. What will the technician do to resolve this problem?

Flash the BIOS to resolve the problem

Explanation:

There is a chip in your computer that has bootup instructions (The Basic Input Output System). It tells your computer how to do very basic things, interact with some hardware, load the operating system, etc.

Flashing it means to update it with a new program. You shouldn't do it unless you need to do so in order to fix something. If power goes out while flashing, you can be left with an unbootable computer.

The process is usually done by using either built-in functionality of the old BIOS, or a MS-DOS-based program (booted from floppy), or more recently, a Windows program (which comes with a special driver to obtain access to hardware). Some motherboards come with secondary firmware on a separate chip, which kicks in if the main BIOS is corrupted (e. g. power failure during flashing). This firmware usually supports flashing the BIOS from a file in a CD or floppy disk.
