- FR (Format Recover)
-
- Version: Advanced Edition only
-
-
- Description: Either saves information about all files on a disk you specify
- or recovers from an inadvertent use of the MS-DOS Format
- command or Recover command by restoring file information.
-
-
- Syntax: Version 4.0: FR [(drive:)] [/SAVE] [/D0 | /D1 | /D2]
- [[[/F(n)] [/B(n)]] | /BW | /TV]
-
- Version 4.5: FR [(drive:)] [/SAVE] [/NOBAK] [/D0 | /D1]
- [/BW] [/NOSNOW]
-
-
- Parameters:
-
- (drive:) The single-letter specifier (A:, B:, C:, etc.) for the drive
- you want to use. Follow the letter with a colon. If you
- include the /SAVE switch and do not specify a drive, FR
- processes the current drive.
-
-
-
-
- /B(n) Specifies the background color for the menu system in version
- 4.0 if you do not provide the /SAVE switch. Use an integer
- from 0 through 15 to specify the color. If you attempt to
- specify identical foreground and background colors, FR adds
- one to the foreground color number before beginning execution.
- Avoid using the high-intensity shade of a color for the
- foreground with the normal-intensity shade of the same color
- for the background (for example, /F12 bright red and /B4 red).
- The default is /B1 (blue). See <NUCOLOR>.
-
- /BW Specifies a black-and-white display.
-
- /D0 Requests the standard screen driver (the default) for a fully
- IBM-compatible computer system.
-
- /D1 Requests the screen driver for a BIOS-compatible computer
- system.
-
- /D2 Requests the ANSI.SYS driver for a non-IBM- compatible
- computer system.
-
-
-
- /F(n) Specifies the foreground color for the menu system in version
- 4.0 if you do not provide the /SAVE switch. Use an integer
- from 0 through 15 to specify the color.
-
- The default is /F15 (bright white). See <NUCOLOR>.
-
- /NOSNOW Prevents screen flicker if your system has an older CGA card.
-
- /NOBAK If you either use the /SAVE switch or select the Save menu
- option, this switch prevents FR from making a backup copy of
- the existing FRECOVER.DAT file before creating a current
- version of the file.
-
- /SAVE Analyzes the disk and creates a FRECOVER.DAT file that FR can
- use in a subsequent recover operation to rebuild the root
- directory, the file allocation table, and all directories. If
- you do not specify /SAVE, FR displays full-screen menus you
- use to select both the command you want (either Save or
- Recover) and the drive you want to process. See the notes
- below. Note that some early releases of version 4.0 do not
- include the menu system.
-
-
-
-
-
-
- /TV Indicates that the utility is running under either TopView or
- Microsoft Windows.
-
- Notes:
-
- To provide maximum protection for your system hard disk, include an FR /SAVE
- command in your AUTOEXEC.BAT file.
-
- In version 4.0, you can use FR only with hard disks. In version 4.5, you can
- use FR with either a floppy disk or a hard disk.
-
- FR cannot recover data on a floppy disk that was reformatted using the MS-DOS
- Format command. Instead, reformat using the Norton SF (Safe Format) utility,
- which is found in version 4.5. Also, FR cannot recover data on a floppy disk
- that was reformatted at a different density.
-
-
-
-
- Notes:
-
- The FRECOVER.DAT file created by the /SAVE option of FR in version 4.5 is not
- compatible with version 4.0.
-
- If you have not previously run FR with the /SAVE switch against a disk you
- are attempting to recover, FR cannot rebuild the root directory or the files
- that were in the root directory. If the files on the disk are badly
- fragmented, the file allocation table might be incorrect. You can avoid disk
- fragmentation by periodically executing the SD (Speed Disk) utility, which is
- found in the Advanced Edition of versions 4.0 and 4.5. Also, FR cannot
- recover files that were in the root directory.
-
- The menu system contains four main options:
-
- 1. Restore information by attempting to locate a FRECOVER.DAT file.
-
- 2. Unformat the disk by rebuilding the subdirectories and the files in
- them (because no FRECOVER.DAT file was created on the disk).
-
- 3. Save disk information in a FRECOVER.DAT file.
-
- 4. Exit.
-
-
-
-
-
-
-
-
-
- The menus also let you specify the drive you want to process. The Recover and
- Unformat options let you cancel the operation if any files currently exist on
- the target disk. Note that the MS-DOS Recover command creates dummy FILE(nnnn
- )entries and that FR can overwrite them.
-
- After you use FR to recover a disk, you might need to execute the MS-DOS
- Chkdsk command or the Norton NDD (Norton Disk Doctor) utility (in version
- 4.5) to ensure that FR restored all files correctly.
