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 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.
You can use the MENU utility or the BACKUP command to back
up your hard disk files. Use the MENU utility or the DISKCOPY
command to make copies of your system and program diskettes. For
instructions on using these programs, see Chapter 5 or see your
MS-DOS manual.
Preparing the hard disk for moving
If you are using the 40MB or 90MB hard disk supplied with the
Equity 386, it automatically moves the read/write heads to a safe
region when you turn off the computer. This prevents the heads from
altering any of the data on the disk if the computer is bumped
accidentally-in its current place or while being moved to a new
location.
If you are using another type of hard disk, however, and you need to
move your computer across the room or across the country, you
should run the HDSIT program just before turning off the computer.
For each hard disk installed in the computer, the HDSIT program
moves the read/write heads to a region of the disk surface that does
not contain data, and locks them securely in position.
To run HDSIT, exit any program you are using so the MS-DOS
command prompt is on the screen. If you copied the MS-DOS files
to the hard disk according to the instructions in Chapter 3, HDSIT
is in the \DOS directory on drive C. Log onto that directory (if
necessary) by typing CD \DOS. Or you can just insert the Reference
diskette in drive A and type A: to log onto that drive. Then type the
following and press
Enter:
