Using Disks and Disk Drives The disk drives in your computer allow you to store data on disk, and then retrieve and use your stored data. This section explains how disks work and tells you how to: 0 Use different types of diskettes and diskette drives LI Care for your diskettes and diskette drives 0 Write-protect diskettes Ll Use a single diskette [...]

A disk is further divided by sectors, which are similar in shape to pie slices. The figure below provides a simple representation of tracks and sectors. Double-sided, double-density diskettes have either 40 or 80 tracks on each side, and double-sided, high-density diskettes have 80 tracks on each side. Diskettes can have 8,9,15, or 18 sectors per t[...]

Your computer uses the read/write heads in a disk drive to store and retrieve data on a disk. To write to a disk, the computer spins it in the drive to position the disk so that the area where the data is to be written is under the read/write head. A diskette has an exposed area where the read/write head can access it. Because data is stored magnet[...]

Cl 360KB drive—Use 5 1/4-inch, double-sided, double-density, 48 TPI, 360KB diskettes. (You can also use single-sided, 160KB or 180KB diskettes.) These diskettes contain 40 tracks per side and 8 or 9 sectors per track. With 8 sectors per track, a diskette holds up to 320KB. With 9, sectors per track, a diskette holds up to 360KB of information, wh[...]

31/2-inch drive/diskette compatibility Because of these incompatibilities, always indicate the diskette type and density when you label your diskettes. (Usually this information appears on the manufacturer’s label.) If you have any combination of the above drives (1.44 MB, 1.2MB, 720KB, or 360KB), you can copy files from one drive to another-usin[...]

0 0 0. 0 0 Keep diskettes away from dust and dirt. Small particles of dust or dirt can scratch the magnetic surface, destroy data, and ruin the read/write heads in a diskette drive. Never wipe, brush, or try to clean diskettes in any way. Keep diskettes in a moderate environment. They work best at normal room temperature and in normal humidity. Don[...]

Write-protecting Diskettes You can write-protect a diskette to prevent its data from being altered. When a diskette is write-protected, you can read it and copy data from it, but you cannot store new data on it or delete any files it contains. If you try to change data stored on a write- protected diskette, MS-DOS displays an error message. To writ[...]

On a 3 ?&inch diskette, the write-protect device is a small switch on the back of the diskette in the lower right comer, shown below. To write-protect a 31/2-inch diskette, slide the switch toward the edge of the diskette until it clicks into position, exposing a hole in the comer. write-protect switch To remove the write protection, slide the [...]

Using a Single Diskette Drive System MS-DOS expects the computer to have at least two diskette drives and displays prompts and messages accordingly. Usually, MS-DOS recognizes the first diskette drive (the top drive) as A and a second diskette drive as B. If you have only one diskette drive, MS-DOS can treat it as both A and B when you need to perf[...]

Note You can load MS-DOS from an application program diskette if that diskette contains the operating system. See your MS-DOS Reference Manual for information about creating a system diskette. Inserting and Removing Diskettes If you have a 5 1/4-inch diskette drive, insert a diskette as follows: hold the diskette with the label facing up and the re[...]

If you have a 3 1/2-inch diskette drive, insert the diskette with the label facing up and the metal shutter leading into the drive, as shown in the following illustration. Slide the diskette into the drive until it clicks into place. When you want to remove the diskette, make sure the drive light is off; then press the release button. When the disk[...]

Formatting Diskettes Before you can store data on a new diskette, you must format it using the FORMAT command. Formatting prepares the diskette so that MS-DOS can write data on it. You need to do this only once, before you use the diskette for the first time. You can also reformat previously used diskettes to store new data. This process erases all[...]

0 You can use the BACKUP command to back up hard disk files to diskettes. Because BACKUP can split large files across two or more diskettes, it makes more efficient use of diskette space than COPY or XCOPY. It also allows you to back up files that are larger than the capacity of your diskettes. See your MS-DOS Reference Manual for instructions on u[...]

Backing up the hard disk While the hard disk is very reliable, it is essential to back up your hard disk files to diskettes in case you lose some data accidentally. Make copies of all your system and application program diskettes before copying the programs to the hard disk. After you create data files on the hard disk, be sure to copy them to disk[...]

Using AUTOEXEC.BAT and Other Batch Files As you get used to using MS-DOS a[...]

When you install MS-DOS, it creates an AUTOEXEC.BAT file for you. To modify the file or create another one, you can use the COPY or EDLIN command, or a word processing program that can save a file as a text-only file. However, be sure to name the file AUTOEXEC.BAT and store it in the root directory of the hard disk or diskette from which you load M[...]

Some copy-protected programs require the computer to run at low speed while accessing the program on a diskette. These programs also usually require you to leave a key disk-the diskette that contains the copy protection-in the diskette drive. If you use a copy-protected program often, you may want to set your processor speed to change automatically[...]

If you frequently use programs that require the processor to operate at low speed or require the automatic speed change when your computer is accessing a diskette, use SETUP to change the processor speed. See Chapter 2 for instructions. If you use these programs only occasionally, you should use the keyboard commands or the ESPEED program (describe[...]

To enter these commands, hold down the Ctrl key and the Alt key and press the + or - key on the numeric keypad. The speed setting remains in effect until you press the RESET button or turn off the computer, or until you change it again using the SETUP program, another keyboard command, or the ESPEED program, described below.
