Cleaning Diskette Drives
You can clean a diskette drive using a commercially available cleaning kit. These kits
contain pretreated diskettes to nonabrasively remove contaminants that accumulate
during normal operation.
If the kit does not contain instructions, insert a pretreated diskette into the drive and
turn on the system. After 20 or 30 seconds, remove the diskette from the drive.
NOTICE: Do not attempt to clean drive heads with a swab. You may
accidentally misalign the heads, rendering the drive inoperable.
