Backing up the hard disk
While the hard disk is very reliable, it is essential to back up
your hard disk files to diskettes in case you lose some data
accidentally. Make copies of all your system and application
program diskettes before copying the programs to the hard disk.
After you create data files on the hard disk, be sure to copy them
to diskettes whenever you revise them to keep your backup
diskettes up-to-date.
Caring for your hard disk drive
Follow these precautions to protect your hard disk drive from
damage and to avoid losing data:
Never turn off or reset the computer when the hard disk
access light is on. This light indicates that the computer is
copying data to or from the hard disk. If you interrupt this
process, you can lose data.
Never attempt to open the hard disk drive. The disk itself is
enclosed in a sealed container to protect it from dust.
Before you move your computer even a short distance, you
need to run the HDSIT program to prepare the hard disk for
moving, as described below.
Preparing the hard disk for moving
If you need to move your computer to a new location, you
should run the HDSIT program-provided on your Reference
diskette-to protect the hard disk during the move.
The HDSIT program moves the disk drive's read/write heads to
a region on the disk surface that does not contain data, and
locks them securely in position. This protects the hard disk from
being damaged if the computer is bumped accidentally.
