hi there can someone tell me what a firmware is ?

It is simply the device's operating system, and often specific to that unique device.

It is effectively the "operating system" for the drive - it is the commands for the microcontroller/processor that controls the voice coil position, PATA/SATA interface, onboard RAM, ECC etc calculations etc
As with any software it evolves, and is quite large. That is why a high percentage is stored on the magnetic platter, with a "bootstrap" or base code on a firmware PROM on the PCB.
