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. For details, refer to Illustrated MS-DOS 5.00 or Illustrated  MS/PC-DOS from Wordware Publishing, Inc.

Section 4 Introduction

Introduction Section 3 introduced you to the Dir command. You used it to display a list of filenames. This section provides more information about filenames and disk directories, sometimes called file paths. Filenames are given to text, data, and program files that reside on a disk. Directory (or path) names are also given to disk directories, which are convenient subdivisions in which categories or families of files may te collected and maintained. Several commands are available to create, list, or delete filenames and directory names. These include: MKDIR (or MD)            Make (or create a new sub directory. CHDIR (or CD)            Change to (or log) a named directory. RMDIR (or RD)            Remove a named directory. PATH                            Provide automatic access to program and batch files located within one or m...

DOS Programs (2)

Internal and External Commands Internal and External Commands:  There are  two kinds of DOS commands. These are called internal and external. The internal commands are loaded into memory when DOS is booted. Internal commands are always available for your use, although they are not seen when you display the disk directory of filenames on your screen. Some internal commands are: COPY                               copies files DEL or ERASE               delete files DIR                                  list are directory of filenames on the logged disk PROMPT                         changes the form of the system prompt REN                      ...

FORMAT

The FORMAT  command prepares a new disk for use by organizing the disk into magnetic tracks and sectors that are readable by DOS. when a disk is formatted, any files on that disk are usually lost. because of the plethora of disk types and capacities, new parameters were added to the FORMAT command in DOS  version 4.01. MS-DOS 5.00 introduction a safe FORMAT command and the ability to UNFORMAT unintentially formatted disks. These parameters and others are presented in the following paragraph and table. FORMAT Command Form:   There are a number of FORMAT command forms. These are described in the following list. CAUTION  BE aware that the FORMAT command erases all files from the disk being formatted.     Many computer users  have accidentally formatted the wrong disk. If you have programs or    document files  you wish to keep, do not format the disk! (DOS 5.00 lets you UNFORMAT     disk, but even with this ve...
