Chapter 9. Protecting Your Data > Avoiding Data Loss

Avoiding Data Loss

Desktop personal computers store information on hard disk drives. These days drives average 4GB–20GB in size, with drives in newer high-end systems hitting as much as 40 or 60GB. (Older systems, however, might have hard drives of only 500MB, and possibly smaller.) The hard drive stores the operating system and application files installed on the system. It typically also includes all the personal and business data that has been loaded or created on that system. The software and data represent a significant investment in money and effort that would be lost if your hard disk were damaged or erased.

Today's personal computers are reliable and economical data processing machines. Like all other machines, however, computers are subject to failures and operator errors. Table 9.1 lists some hardware and software problems discussed in this chapter and suggests ways to prevent these problems.
