CVP-409/407 Owner’s Manual 21
Introduction
Handling the Floppy Disk Drive (FDD) and Floppy Disks
(The floppy disk drive is optional. For instructions
on installing the floppy disk drive, see page 212.)
The floppy disk drive lets you save original data you’ve cre-
ated on the instrument to floppy disk, and allows you to
load data from floppy disk to the instrument.
Be sure to handle floppy disks and treat the disk drive with
care. Follow the important precautions below.

Floppy Disk Compatibility

• 3.5" 2DD and 2HD type floppy disks can be used.

Formatting a Floppy Disk

•If you find that you are unable to use new, blank disks or
old disks that have been used with other devices, you
may need to format them. For details on how to format a
disk, see page 68. Keep in mind that all data on the disk
will be lost after formatting. Make sure to check before-
hand whether or not the disk contains important data.
n
Floppy disks formatted on this device may or may not be useable
as is on other devices.

Inserting/Removing Floppy Disks

Inserting a Floppy Disk into the Disk Drive:

• Hold the disk so that the label of the disk is facing
upward and the sliding shutter is facing forward, towards
the disk slot. Carefully insert the disk into the slot, slowly
pushing it all the way in until it clicks into place and the
eject button pops out.
n
Never insert anything but floppy disks into the disk drive. Other
objects may cause damage to the disk drive or floppy disks.

Removing a Floppy Disk

• After checking that the instrument is not accessing* the
floppy disk (checking that the use lamp on the floppy
disk drive is off), firmly press the eject button at the
upper right of the disk slot all the way in.
When the floppy disk is ejected, pull it out of the drive. If
the floppy disk cannot be removed because it is stuck,
do not try to force it, but instead try pressing the eject
button again, or try re-inserting the disk and attempt to
eject it again.
* Access of the disk indicates an active operation, such as
recording, playback, or deletion of data.
If a floppy disk is inserted while the power is on, the disk is
automatically accessed, since the instrument checks whether
the disk has data.
• Be sure to remove the floppy disk from the disk drive
before turning off the power. A floppy disk left in the
drive for extended periods can easily pick up dust and
dirt that can cause data-read and -write errors.

Cleaning the Disk Drive Read/Write Head

• Clean the read/write head regularly. This instrument
employs a precision magnetic read/write head which,
after an extended period of use, will pick up a layer of
magnetic particles from the disks used that will eventu-
ally cause read and write errors.
•To maintain the disk drive in optimum working order
Yamaha recommends that you use a commercially-avail-
able dry-type head cleaning disk to clean the head about
once a month. Ask your Yamaha dealer about the avail-
ability of proper headcleaning disks.

About Floppy Disks

Handle floppy disks with care, and fol-

low these precautions:

• Do not place heavy objects on a disk or bend or apply
pressure to the disk in any way. Always keep floppy disks
in their protective cases when they are not in use.
•Do not expose the disk to direct sunlight, extremely high
or low temperatures, or excessive humidity, dust or liq-
uids.
• Do not open the sliding shutter and touch the exposed
surface of the floppy disk inside.
•Do not expose the disk to magnetic fields, such as those
produced by televisions, speakers, motors, etc., since
magnetic fields can partially or completely erase data on
the disk, rendering it unreadable.
•Never use a floppy disk with a deformed shutter or hous-
ing.
•Do not attach anything other than the provided labels to
a floppy disk. Also make sure that labels are attached in
the proper location.

To Protect Your Data (Write-protect Tab):

•To prevent accidental erasure of important data, slide the
disk’s write-protect tab to the “protect” position (tab
open). When saving data, make sure that the disk’s write-
protect tab is set to the “overwrite” position (tab closed).
CAUTION
Do not remove the floppy disk or turn off the instrument
itself while the disk is being accessed.
Doing so may result not only in loss of data on the disk
but also damage to the floppy disk drive.
