4.6 SATA SMART Drives

The Self Monitoring Analysis and Recording Technology (SMART) SATA drives for the HP
Personal Computers have built-in drive failure prediction that warns the user or network
administrator of an impending failure or crash of the hard drive. The SMART drive tracks fault
prediction and failure indication parameters such as reallocated sector count, spin retry count,
and calibration retry count. If the drive determines that a failure is imminent, it generates a fault
alert.

4.7 Drive Capacities

The combination of the file system and the operating system used in the computer determines the
maximum usable size of a drive partition. A drive partition is the largest segment of a drive that
may be properly accessed by the operating system. A single hard drive may therefore be
subdivided into a number of unique drive partitions in order to make use of all of its space.
Because of the differences in the way that drive sizes are calculated, the size reported by the
operating system may differ from that marked on the hard drive or listed in the computer
specification. Drive size calculations by drive manufacturers are bytes to the base 10 while
calculations by Microsoft are bytes to the base 2.
