With the advent of IDE (Integrated Drive Electronics), manufacturers started including the drive controller in the same housing as the hard drive itself. This made for faster access times as well as fewer issues with moving a drive from one controller to another (as with MFM, RLL, and SCSI drives)
The controller acts as an interpreter, getting requests from the computer and taking control of physically moving the drive heads, controlling the spindle speed, self-diagnosis (S.M.A.R.T.) and so forth.
For today's hard drives, the hard drive controller is firmware on a circuit board on or inside the drive housing.

Motherboard/Mainboard
You would have to look inside your computer and take the circuit board out and examine it. It should have the information on it.
That would probably be the circuit board.
a 'hard disk card' could refer to a PCI, PCI-E controller card for a computer, or a circuit board on the hard drive, or a solid-state drive (which is just one circuit board).
A motherboard is the main Printed Circuit Board inside a computer, it holds most of the important parts of the computer.
no fuse. there is only a relay with some electronic components called a fuel pump controller. this is encased inside a black plastic unit under the steering column. in case of short circuit, the printed circuit on the mother board burns out, thus acting as a protection.
The flat circuit board inside a computer is called Mother Board. Yes , this provide all the circuitry for the computer and connect different components together. Then the components have their own circuit boards which provide internal and external connections.
The main circuit board of the computer is the motherboard.
