When you swap diskettes this way, it is a good idea to
write-protect the original diskette so you don’t accidentally
write over it. (See “Write-protecting Diskettes” on page 3-15.)
Using a Hard Disk
The removable hard disk in your computer has been prepared
for use at the factory. It also may have MS-DOS and Windows
installed. If you plan to use MS-DOS or Windows, you can
install your application programs and begin work. See the
documentation that came with your programs for instructions.
Follow these precautions to protect your hard disk from
damage and to avoid losing data:
Never turn off or reset the computer when the hard disk
drive light is on. This light indicates that the computer is
copying data to or from the hard disk.
After turning the power off, wait 20 seconds before moving
the computer. This allows the disks in the drive to stop
spinning and the hard disk read /write heads to lock in
place so you do not damage the drive.
Never remove the hard disk drive when the computer is on.
Backing
Up
the Hard Disk
Although the hard disk is very reliable, be sure to back up your
files onto 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.
