1.2.5 Diskettes
Following are some tips on diskette management:
•Always make backup copies of diskettes that contain important data or
program files.
•Keep diskettes away from magnetic fields and sources of heat.
•Avoid removing a diskette from a drive when the floppy drive activity
light is on.
•Write-protect your diskettes to prevent accidental erasure. To do this,
slide the write-protect tab to the write-protect position.
•When you put a label on a 3.5-inch diskette, make sure that the label is
properly attached (flat on the surface) and within the labelling area
(area with slight surface depression) on the diskette. An improperly
attached label may cause a diskette to get stuck in the drive when you
are inserting or removing it.
