A hard disk's directory and file allocation tables contain the address information the operating system needs to determine where to store or retrieve data.
With hard disks as cheap as they are now it doesn't make any sense to try to learn an advanced operating system like Linux without plenty of disk space.
In Linux hard disks are treated as devices and the location of the device files is the /dev directory.

Modern hard disks have an increasing range of disk transfer rates from the inner diameter to the outer diameter of the disk.
Hard disks are circular, they store data as 0s/1s using magnetic particles, and store them circularly in tracks, just like that old gramaphone record that you saw at your grandfather's attic.
There are several indications that data has been lost and we have recovered data from hard disks where normally the data loss situation has been considered a write-off.

With hard disks or compact discs, maximum access time is mea sured as the time it takes to move from one end of the disc to the other end.
Hard disks, in common with magnetic tape media, have the recording layer on top of a substrate.
This is why hard disks are sealed-a good reason for not undoing them, although they still work with the top off.

Hard disks have a shorter access time and outperform CD-ROM in this area By contrast, CD-ROM performs relatively well in accessing the lengthy files characteristic of multimedia That said, it still takes half a minute to access just 5 photographs using a 4x drive.
Hard Disk Drive provides for more software storage space than is available on the 6544 standard dual-floppy diskette drive.
When hard disks were expensive, someone created a way to utilize older, smaller disks to create one large virtual disk but now that disk drives are inexpensive, RAID is used for data integrity and speed.
