WINCHESTER SUPPLEMENT
Hardware Features
After you read pages 1.13 and 1.14 of the Operation section
of the User's manual, you will notice an important difference
between your Desktop Computer and the two-drive unit de-
scribed in the manual.
One of the two disk drives has been replaced by a Winchester
drive. In place of the Diskette Load Slot, Disk Drive Door,
and LED Disk Access Indicator, you will see only an LED
Disk Access Indicator.
You need to know and understand a couple of important facts
about the care of your Winchester drive.
• Ne v er drop your Winchester drive system or subject it to
any other physical shock. If the Computer is accidentally
dropped, even from only two to three inches, the Winches-
ter drive may fail to operate. If this occurs you should con-
tact your local ZDS representative for service.
• Th e built-in disk of your Winchester drive cannot be phys-
ically removed from the drive. However, information can
be removed, stored, and replaced with other data. You
will learn how to do this later in this supplement and in
the Winchester section of your operating system manuals.
WINCHESTER DISK DRIVES
A Winchester Disk Drive System, such as the one in your
Z-100 Desktop Computer, is only one of a family of disk sys-
tems generally called "hard disks."
The disk itself is a carefully machined and polished non-
magnetic metal platter that is coated with a magnetic material,
similar to that used by floppy disks and audio and video tape.
Hard disks come in a variety of sizes, capacities, and config-
urations. Many have multiple disks and some are even remov-
able, being enclosed in "disk packs," or "cartridges."
