Not sure about the question being asked.

That information is likely stored on the motherboard via CMOS.

Not on the drives....

What are you trying to accomplish?

Drive info is actually stored on the drive.

For instance, the SMART data is in hidden tracks (I think) on the physical drive.


But yes...what is the OP wanting to do with this info?

BIOS is just one type of firmware. It's called "Firmware" because it stored in hardware but programmable like software, just a play of words. Most if not all "Plug and Play" HW have some kind of BIOS at it's HW. That way MB BIOS, OS and SW can find exactly what is need for it's operation and find proper divers. Before P n'P we had to find and change settings in OS manually, Settings like IRQ, memory range and addresses. iO etc.
