- PROGRAM USAGE
- -------------
-
- FDFORMAT formats Disks in many different MSDOS formats. It does the follwing
- things.
-
- 1) Formatting of 720 kB Disks in an AT 1.2 MB drive
- 2) significantly increasing the storage of your diskettes (e.g. Using 1.44 MB
- on HD-5¼"-Disks)
-
- If you want to format a 720 kB Disk in an AT-drive, then type
-
- FDFORMAT <drive>: T80 S9
-
- If you want to increase the storage of your disks, then type
-
- FDFORMAT <drive>: T41 S10 (for 360 kB-Drives)
- FDFORMAT <drive>: T82 S10 (for 720 kB-Drives)
- FDFORMAT <drive>: T82 S18 (for 1.2 MB-Drives)
- FDFORMAT <drive>: T82 S21 (for 1.44 MB-Drives)
-
- Always add a P at the end of the command, when using a PS/2 Computer. Some
- Computers cannot use Disks with higher capacity without the TSR FDREAD
- installed. If so, simply type the Command FDREAD before using FDFORMAT
- or a Disk with higher Capacity. You may wish to add FDREAD to your
- AUTOEXEC.BAT or CONFIG.SYS (DOS 4.00) File.
-
- The exact description of the FDFORMAT Command Syntax is:
-
- FDFORMAT <drive>: [options]
-
- Options are:
-
- Tnn : Format nn Tracks
- Snn : Format nn Sectors per Track
- Hn : Format n Heads
- P : Special option for PS/2 Computers
- V : Do not verify the diskette (and save 33% time)
- Gnnn : Use a GAP-Length of nnn (*)
- Inn : Use an interleave Factor of nn (*)
- Bnnn : Use a BIOS-Disk-Descriptor Byte of nnn (not on XT) (*)
- Cn : Use n sectors per Cluster (1 or 2) (*)
- Dnnn : Use nnn Root Directory Entries (*)
- Fnn : Shift sectors on adjacent tracks with a distance of nn sectors (*)
-
- Options with (*) are adjusted to the best value automatically. You may
- do some experimenting with it.
-
- - Reducing the GAP-Length may speed up the disk perfomance
- - Reducing the Root Directory Entries brings you additional storage
-
-
- The following table shows you, what Options are correct for specified formats:
-
- Options Storage on Disk Allowed in Disk-Drives
