Unformatted text preview: s of computers may use different formatting style resulting in different capacities for the same disk. For example, a double-density 3'/2-inch diskette used on Macintosh systems has a storage capacity of 800 KB instead of 720 KB mentioned in Figure 8.21. Tips for proper usage and handling of floppy disks Although floppy disks are non-volatile storage media, data stored on them can still be lost or damaged if they are not handled properly. Here are a few tips for the proper usage and handling of floppy disks: 1. To prevent loss of stored data due to unintentional erasing/over-writing, the floppy disks should always be kept write protected when not in use. Fortunately, all floppy disks have a simple write protection mechanism. For example, as shown in Figure 8.19, a 5%inch floppy disk can be write protected by covering the write-protect notch located near the upper-right corner of the disk covei with a write-protect sticker. These stickers are supplied together with the floppy disks when yov purchase them. Similarly, as shown in Figure 18.20, a 3%-inch floppy disk can be write protected b) sliding a plastic tab in the upper-left corner of the plastic cover such that a hole shows through the disk cover. 2. No sharp-edged device should be used for marking/writing something on the flexible type 5'/4-inch diskettes. A felt-tip pen should be used to write some information on the disk label and the writing should be done very gently without applying pressure. 3. A floppy disk should never be forced into or removed from a disk drive when the drive is in operation (its light indicator is on). Doing so may cause the read/write head to break, or may cause the read/write head to scratch the disk surface, resulting in damaging the disk or the data stored on it. 4. Their recording surfaces should never be touched by hand. These surfaces are already exposed through the oval cutout in case of 514-inch diskettes, and can be exposed by sliding the metal cover back by hand in case of 3'/2-inch diskettes. 5. The flexible type...
