moving from a cramped studio apartment into a large,
comfortable home with room to spare! Your Mac Disk

folders and documents to open and close
• Ease of Use-Mac Disk minimizes inserting,
swapping, removing I and stonng of diskettes
• Dependability -Mac Disk information storage is
much more reliable than diskette storage

Getting Started
About Your Mac Disk
Your Mac Disk has two volumes for storage of your
documents and applications. A'volwne is a designated
storage area with a name and size. The volumes on your
Mac Disk are a l-megabyte volwne named System and
a 2 .. megabyte volume named User. When you have
connected your Mac Disk to yo~ Macintosh and started
up with the Mac Disk System Diskette, the icons for
these volwnes will appear on the desktop.
The System volume is intended for storage of your
Mac Disk system software and the User volume for
storage of your applications and documents. If you want
separate volumes for your documents and applications,
you can add them using the Volume Manager application
that Davong provides on your Mac Disk System
Diskette.
Once you have copied your folders, applications, and
documents to your Mac Disk volumes, you can operate
directly from your Mac Disk. You will probably need
diskettes only to start up your system, back up (copy)
important infonnation, or run copy-protected software
(applications that cannot be copied to the hard disk),
Saving Packing Materials -
When you unpack your Mac Disk, be sure you save
the packing
material. If you ever change locations or need
to send your Mac Disk for repair, you will need this
packing material.

-------', , Your Hardware
Attaching your Mac Disk to your Macintosh computer is a
very
simple task. You only need to connect one cable and
plug in the power cord.

If you have 115 VAC voltage at your wall outlet, go on
to Connecting the Interface Cable in this chapter.
If you have 230 VAC voltage, see Appendix A for
instructions on changing the Mac Disk voltage setting and
fuse. If you do not know what the voltage is in your
geographical area, your Davong dealer can tell you which

The interface cable in your adapter ldt can be
connected to either the modem or printer port on the
back of your Macintosh. If it is connected to the printer
port, printer outpUt will be· redirected to the modem port.
'Secertain thatyour appli'Canoit"'\Vf.ll redirectprlnter··'· ,.
output before you connect to the printer port. If it will
not, you could lose. data or your Mac Disk data could
become corrupted.. .
If you are not certain about your application,
connect Mac Disk to the modem port. If you have to use
a modem that will only connect to the modem port, you
can connect Mac Disk to the printer port long enough to
use the modem, then switch back to the modem port.
Power offbefore you disconnect your Mac Disk. After you
switch ports, power on and start up your system again.
