Hard Disk Problems
If you have problems with your hard disk when you first start to use
it, make sure it is properly set up. (See the instructions for setting
up the hard disk in Chapter 3.) Then try the following steps:
1. Be sure the switch marked HDD POWER, on the back of the
computer, is on.
2. If you cannot load MS-DOS from your hard disk, you
may be missing one of the MS-DOS system files. Turn off
your computer and insert your working copy of the Startup/
Operating 1 diskette into drive A. Then turn on your computer
and log onto your hard disk drive.
If this procedure works, make sure the file COMMAND.COM
is in the root directory of your hard disk. You can check this by
typing the following and pressing Enter:
DIR C:\COMMAND.COM
If MS-DOS responds with the message
File not found,
use the COPY command to copy COMMAND.COM from the
diskette to the root directory of the hard disk, then restart your
system.
If COMMAND.COM is already in the root directory, use the
MENU utility (see Chapter 5) or the FC command (see your
MS-DOS manual) to compare the COMMAND.COM file on
your diskette with the COMMAND.COM file in the root
directory of your hard disk. If the files don’t match, use the
COPY command to replace the COMMAND.COM file on
your hard disk with the COMMAND.COM file on your
diskette.
3. If the hard disk still doesn’t work, the root directory of your
hard disk may be missing some hidden MS-DOS system files.
(Hidden files are files whose names do not appear in a directory
listing. MS-DOS normally keeps two hidden files in the root
directory of your hard disk.)
