Reading a disk involves accessing and retrieving data that is already stored on the disk, while writing to a disk involves adding new data or modifying existing data on the disk. Reading does not change the content of the disk, whereas writing alters the information stored on the disk.

It doesn't really control anything, rather it flashes on whenever there is hard disk activity (i.e. reading from or writing to the disk)
Sequential access refers to reading and writing dataæconsecutively. For instance, like a hard disk or compact disc, the information can only be used in the same order it was created.
This is called "Formatting"
Your disk is not reading few files properly
File handling is simply the process of opening, reading, writing and closing files. Files are simply streams for input and output, or the "serialisation" of objects. In other words, reading and writing data to and from disk storage.
Yes, if the write-protect notch on a disk is open, it typically means that the disk is in a write-protect mode, preventing any writing or modification of data. However, you can still read from the disk, as reading does not alter the data stored on it. If you want to write to the disk, you would need to close the write-protect notch.

Hard Drive activity indicators .....It tells you your computer's hard disk is either writing something or reading something.
A hard disk is the physical medium information storage device of most computerized systems. It is an actual disk that rotates at high speed. The surface is coated with magnetic material, and data is stored magnetically on the surface. A tiny read/write head on the end of an arm that can move over the surface of the disk does the reading and writing to transfer the information to and from the medium.
The card that controls the read/write head and motor in a hard disk is called the Disk Controller or Hard Disk Controller (HDC). It manages data flow between the drive and the computer, ensuring accurate reading and writing of data on the disk platters. The controller also handles tasks like error correction and the translation of logical block addresses to physical locations on the disk.
