General disk handling information
If you’re new to working with floppy disks are not sure as to how you should
handle these delicate accessories, read this section for some useful informa-
tion.
Inserting a Disk into the drive
Floppy disks must be inserted into the disk drive label side up and shutter first.
Push the disk firmly in until it “clicks” into place.
Avoid forcing a disk into the drive and hold the disk straight while inserting it.
Ejecting a Floppy Disk
Before ejecting a disk, make sure that the disk drive operating LED is off and
that the PS1000 display is not currently showing a disk operating message.
To extract the disk, press the eject button and remove the disk.
The Write Protect Tab
Floppy disks contain a write protect tab which allows you to protect valuable
data from being accidentally overwritten.
To prevent writing data to disk and so avoid accidental erasure, slide the tab
fully down to “open” the window.
To permit writing data to disk, slide the tab fully up to “close” the window.
Use a pen or other pointed object to set the tab as shown.
Handling Floppy Disks
When handling floppy disks, certain precautions should be taken to avoid dam-
age and/or data loss.
• Do not open the metal protection shutter or touch the surface of a disk.
• Do not transport PS1000 with a floppy disk inserted in the disk drive. Vibra-
tions may cause the disk drive head to scratch the disk, rendering it unus-
able.
• Do not store or place floppy disks in close proximity of television sets, com-
puter monitors, loudspeakers, power transformers, or other devices that
are potential sources of magnetic fields. Doing so may render the disk
unusable.
• Do not store or place floppy disks in locations subject to extremes of tem-
perature and humidity, direct sunlight, or excessive dust and dirt.
• Do not place objects on top of a floppy disk.
• Return disks to their protective cases after use.
Back-up copies
It is advisable to keep back-up copies of all your floppy disks. “Back-up” is
technical jargon for “a second copy” of a disk. Back-up copies of your data
stored in a safe place are extremely important, to safeguard against the loss or
damage to the originals, or against the loss of data contained in the instrument.
To copy data from one disk to another, you always need to go through the RAM
memory first, loading the original to RAM memory then saving it to the destina-
tion back-up floppy disk.
Disk Drive Head Cleaning
After a prolonged period of use, disk save and load errors may become fre-
quent due mainly to dirty disk drive heads, indicating that the disk drive head
may need cleaning. This can be done using a good-quality fluid-type head
cleaning kit for 3.5 inch (double-sided) disk drives. Do not use a cleaning kit
intended for single-sided disk drives.
1. Moisten the cleaning disk with cleaning fluid.
2. Insert the cleaning disk into the disk drive.
