For today's hard drives, the hard drive controller is firmware on a circuit board on or inside the drive housing.
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).
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.
Im sorry, but the simple answer is no. a u3 software cant run on any flash drive cos it needs the right hardware as well as software. The u3 software depends upon an IC controller on the PCB (printed circuit board). Without an IC controller, you have an ordinary flash drive
A PCBA ("printed circuit board assembly") is the physical board that has all the chips on it.

Internal structure of pen drive A printed circuit board carrying the circuit elements and a USB connector.The circuitry is protected inside a pair of plastic cases (connected to each other by means of mechanical hooks) which can be carried in a pocket or a key chain. The USB connector is protected by either retracting into the body or by covering by a removable lid. There are two chips, one is the USB controller and the other is the flash memory chip.
mother board is the central printed circuit board in many modern computers.It holds many of the crucial components of the system.It is known as main board also which has a port to connect the USB drive.
