Operating Your Computer 2-13
Using the Hard Disk Drive
Your computer comes with a hard disk drive as drive C. A hard disk drive
is a storage device with non-removable, rotating, magnetic storage
platters inside it. It is where your operating system and application
software programs are stored.
Your hard disk drive is a 2.5-inch IDE (Integrated Drive Electronics) hard
disk drive. This type of drive embodies the latest in fast, reliable mass
storage by integrating all the control circuitry necessary for operation
directly onto the drive itself. This allows the drive manufacturer to
carefully optimize drive performance.
The system comes with a built-in heater that automatically turns on for
low temperature operation. The AC in / HDD heater on indicator blinks
red when heater is on. In low temperature environments, the user is
recommended to operate the system using AC power to conserve battery
life.
CAUTION:
Make regular backups of your data files from your hard disk drive to CD discs or
other storage media.
Never try to remove or install the hard disk drive while the computer is powered on.
Doing so can result in loss of data, and can damage the computer and the hard disk
drive’s sensitive circuitry.
Never turn off or reset the computer while the hard disk drive in-use indicator is on.
