- Command QDR Version 2.6
- ----------- Nov 9, 1986
-
-
- Purpose
- -------
- Re-format a floppy disk quickly, optionally with a new volume
- label, deleting all files and sub-directories.
-
- Format
- ------
- QDR [d:][label] [/F][/1][/3][/4][/8] [/N] [/V]
-
- Remarks
- -------
- The d: parameter supplies the drive letter, A to K. If no drive
- letter is supplied, A is used. 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
-
- 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.
-
- Use the /F option to force a full format of all tracks. The /1,
- /3, /4, and /8 options apply to a full format.
-
- 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 option to receive a display of the
- cluster numbers that are marked as not usable.
-
- The DOS error level is set to 0 for successful completion, or to
- 1 if any errors occur.
-
- Options
- -------
-
- /F - forced format; uses BIOS to format and verify each track
- /1 - forces single sided format, SSSD/8 or SSSD/9
- /3 - forces DSQD format on 720K capacity drives
- /4 - forces DSQD format on 1.2 mb drives
- /8 - forces 8-sector format; for SSSD/8 or DSDD/8
-
- /N - no prompt; skips the "Press ENTER" message and reply
- /V - verbose messages; displays a message for each cluster
- that is marked as unusable
-
- 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, and DSDD/9. 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.
-
- 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.
