   Let’s understand how disks work by building up a model one track at a time. Assume we have a simple disk with a single track (Figure 37.1). This track has just 12 sectors, each of which is 512 bytes in size (our typical sector size, recall) and addressed therefore by the numbers 0 through 11.

   Hard drives are packaged carefully to prevent dust and other airborne particles from interfering with the drive’s operation. In combination with the air motion caused by the spinning disc, a very fine air filter is used to keep dust out while maintaining the air pressure necessary to cushion the spinning discs. Hard drives intended for

   What does a hard drive do?

   • Hard disks do one thing well — they provide storage space for data and operating systems. They also give computers the ability to remember things when the power goes out. In this article, we'll take apart a hard drive so that you can see what's inside, and also discuss how they organize the gigabytes of information they hold in files!

   What is an example of a hard disk?

   • A computer's internal hard drive is an excellent example of a hard disk. This disk is typically mounted inside the computer case on top of the power supply unit. The hard disk contains spinning disks (called platters) that store data on their surfaces.

   What is a hard disk drive?

   • In this chapter, we dive into more detail about one device in particular: the hard disk drive. These drives have been the main form of persistent data storage in computer systems for decades and much of the development of file sys-tem technology (coming soon) is predicated on their behavior.

   What is a hard drive made of?

   • Hard drives, also called hard disk drives, hard disks, or fixed disks, consist of several small, identical disks called plattersstacked together and placed in a sealed enclosure to protect them from dust or damage. The platters are made of aluminum or glass, and are coated with a thin layer of magnetic media that stores the actual data.

   How does a hard disk drive work?

   • Here is a typical hard-disk drive: It is a sealed aluminum box with controller electronics attached to one side. The electronics control the read/write mechanism and the motor that spins the platters. The electronics also assemble the magnetic domains on the drive into bytes (reading) and turn bytes into magnetic domains (writing).

   How many hard disks does a computer use?

   • Nearly every desktop computer and server in use today contains one or more hard-disk drives. Every mainframe and supercomputer is normally connected to hundreds of them, while even VCR-type devices and camcorders use hard disks instead of tape. So, what is a hard drive, and how does it operate these countless hard disks?
