FORMAT(2)

FORMAT /Q- Quick format takes less than 10 seconds; this command removes  the files allocation table and root directory; it does not scan the disk for bad areas. The /Q switch cannot be used if you change the capacity of the disk, i.e., format a 1.44MB diskette as 720K.

FORMAT /V: labelname-Lets you assign a volume label. Otherwise, you are prompted to enter one of the following operation. Volume labels are uo to 11 characters long.

FORMAT /F:size-Specify the size of the disk belong formatted. Sizes are entered as follows.

         Disk Size                   Use
         5.25 160K                 160, 160k, 160KB
         180K                         180, 180k, 180KB
         320K                         320, 320k, 320KB
         360K                         360, 360k, 360KB 
         3.5 720K                   720, 720k, 720KB
         1.44M                       1440 , 1440K, 1440KB, 1.44, 1.44M, 1.44MB
         2.88M                       2880 , 2880K, 2880KB, 2.88, 2.88M, 2.88MB

FORMAT Command Dialogue: When the FORMAT command is used, there is a build-in dialogue that keep you informed about the formatting progress. A summary of what has been accomplished is displayed when formatting is completed. The precise dialogue varies slightly with different versions of DOS. The FORMAT command activity provides an example of what you might see.

FIXED Disk Formatting: You can use the FORMAT command to format a fixed (hard) disk. A factory-fresh fix disk must undergo a low-level format before the FORMAT command is used. Low level formatting, which organizes tracks and sectors, is accomplished using special disk manager utilities supplied by the drive manufacturer.  These utilities also perform other operations including disk partitioning, high-level formatting, and the installation of the DOS system files.

The DOS DEBUG command is something used to perform low-level formatting. After the low-level process is completed using DEBUG, the DOS FDISK command is used to partition a fixed disk. Low-level formatting and partitioning is beyond the scope of this book. Here, you should just know that these operations must be performed.

MEM

MEM The MEM command was introduced in DOS version 4.01 and memory information. The MEM command is entered alone or with a modified slightly in MS-DOS 5.00. MEM is used to display system memory information. The MEM command is entered alone or with a parameter. MEM-Displays to all system memory values, including expanded and extended memory values. MEM PROGRAM--Displays programs presently loaded in memory with used and unused memory. You may use /P if you are using DOS 5.00 MEM/DEBUG--Dispiays a list of programs, device drivers, install drivers, and used unused memory. You may use / if you are using DOS 5.00. MEM CLASSIFY (or MEM /C)-Displays programs and cor-responding memory usage. The largest available memory block is also displayed. You may use /C if you are using DOS 5.00. Typing MEM and pressing Enter displays information similar to the following (typical of DOS 5.00): C:\>MEM                   655350 bytes total conventional memory        

Filenames

It is important to understand DOS file naming conventions and their use. Here, filenames and some special filename "tools" called wild cards and literals are described. What is a File name?   Every program and data file is given a name to differentiate it from other programs and data files. A program is one or more computer instructions collected into a file. A data file is normally a collection of characters (or data) that make up a document, like a letter, or a database, like a collection of accounting transactions or customer records. Descriptive filenames are normally used. For example, if you create and save a letter to Mom, you might give it the filename MOM.LTR. A letter to Dad could be called DAD.LTR. A word processing program file might have the filename WP.COM. Examine these filenames a little closer. First, notice that each filename is meaningful. This is important if you want to know what is in a file by looking at its name. Obscure filenames are of little u

Disk Construction

The various parts of standard 5.25- and 3.5-inch disks are contained in Figure 1-2. A description of each part is also provided. Write protect notch--When covered, prevents information from being recorded on the disk; when uncovered, information can be recorded. Temporary label--An adhesive-backed label allowing the contents of a disk to be identified. Permanent label--When used, contains disk manufacturer and capacity information. Exposed recording surface--Metal oxide surface used to magnetically record data. Do not touch! Protective jacket --House magnetic disk; provides protective cover. Disk sleeve (envelope)--Used to store disks;prevents  accidental contact with exposed surface. Protective slide --Protects magnetic media surface; slides open when inserted into a diskette drive (only on 3 1/2-inch diskettes).
