- Command QDR Version 3.2b
- ----------- Oct 24, 1987
-
-
- Purpose
- -------
- Re-format a floppy disk quickly, optionally with a new volume
- label, thus deleting all files and sub-directories on a diskette.
-
- Format
- ------
- QDR [d:][label] [/F] [/N] [/V] [/B] [/Q]
- [/1] [/2] [/3] [/4] [/8]
-
- Remarks
- -------
- The d: parameter is required and it supplies the drive letter.
- A fixed disk can not be re-formatted.
-
- You may supply a volume label (up to 11 characters) immediately
- following the drive letter. For example:
-
- QDR b:scratch
-
- Use the /F option to force a full format of all tracks. The /1,
- | /2, /3, /4, and /8 options apply to a full format, and specify
- | the disk type.
-
- Bad clusters remain marked as bad unless a full format is
- used, then clusters are marked as unusable if they can not be
- formatted. Use the /V (verbose) option to receive a display of
- the cluster numbers that are marked as not usable.
-
- The /N option suppresses the "press ENTER to continue" prompt.
- Otherwise, press the enter key to reformat the disk, or the
- ESCape key to cancel.
-
- The DOS error level is set to 0 for successful completion, or to
- 1 if any errors occur.

- Command QDR Version 3.2b
- ----------- Oct 24, 1987
-
- Options
- -------
-
- /F - forced format; uses DOS to format and verify each track
-
- /1 - forces single sided format, SSSD/8 or SSSD/9, on 360 kb drives
- | /2 - forces DSHD format on 1440 kb capacity drives
- /3 - forces DSQD format on 720 kb capacity drives
- | /4 - forces DSDD format on 1.2 mb capacity drives
- /8 - forces 8-sector format, SSSD/8 or DSDD/8, on 360 kb drives
-
- /N - no prompt; skips the "Press ENTER" message and reply
-
- /V - verbose messages; displays a message for each cluster
- that is marked as unusable
-
- | /B - use disk BIOS routines only for formatting; if omitted,
- | the DOS routines used for formatting are determined by the
- | version of DOS in use. This option is supplied as an
- | alternative to the default because QDR may not be able
- | to format a new diskette when certain device drivers or
- | versions of DOS are installed.
-
- | /Q - quick format without verification or bad track marking.
- | If the target disk has bad spots, write errors may result.
- | This option is NOT recommended for formatting new
- | diskettes.
-
-
-
- Formatting
- ----------
-
- To perform a full format of a disk sectors, use the /F options.
- It is recommended that you use DOS FORMAT since QDR is not much
- faster when doing a full format. Both mark bad clusters.
-
- You may suppy /1 to force SSSD format, /4 for DSQD (1.2mb), or
- /3 for DSQD (720kb), or /8 for eight-sectors (SSSD or DSDD).
-
- Unless /F is used, the diskette must have been previously
- formatted. The allowable diskette formats are: DSQD (1.2mb or
- 720kb), SSSD/8, SSSD/9, DSDD/8, DSDD/9, and DSHD (1.44 mb).
- When information is available for other drive types, they will
- be added to the data in the internal device table. Your system
- hardware and software must support the device type.
-
- Command QDR Version 3.2b
- ----------- Oct 24, 1987
-
- Examples
- --------
-
- o Reformat a previously formatted and used diskette. Write a
- volume label of SCRATCH:
-
- QDR A:scratch
-
- o Alternately format new diskettes in drives A and B.
- First, create a BAT file called TWOFOR.BAT with these commands:
-
- QDR A: /F/N
- QDR B: /F/N
- TWOFOR
-
- Then, issue the command TWOFOR. When the last diskette has been
- formatted, press ctrl-C to abort the program.
