Most operating systems let you keep related files together in
directories and subdirectories so they are easy to find and use.
See your operating system manual for instructions on
managing your files and directories.
Note
A hard disk must be partitioned and formatted before you
can use it. Be sure you have performed the procedures
described in your operating system manual to prepare your
hard disk for use.
Backing up the hard disk
While the hard disk is very reliable, it is essential to back up
your hard disk files to diskettes or tapes 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. Be sure to to back up your data files regularly to
keep your backup diskettes or tapes up-to-date.
Curing for your hard disk
Follow these precautions to protect your hard disk drive from
damage and to avoid losing data:
q 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.
q Never attempt to open the hard disk drive. The disk itself is
enclosed in a sealed container to protect it from dust.
