- DT (Disk Test)
-
-
- Description: Checks a disk for physical damage. In versions 4.0 and later,
- you can mark a cluster as either usable or unusable, check
- only a specific path, or attempt to move data that is stored
- in bad clusters to a new area.
-
-
- Syntax: Version 3.0: DT [(drive:)] [/F | /D | /B]
-
- Version 3.1: DT [(drive:)] [/F | /D | /B] [/LOG]
-
- Version 4.0: 4.5) DT [(drive:)][[(path) [/S]] | [/F | /D |
- /B]][/C(n)[-] ...]
-
- DT [(drive:)][(path)](filespec)
-
- Parameters:
-
- (drive:) The single-letter specifier (A:, B:, C:, etc.) for the drive
- you want to test. Follow the letter with a colon. The current
- drive is the default.
-
-
-
-
- (path) The full name (C:\WP\LETTERS) of the directory containing the
- files whose clusters you want to test. If you include either
- the /B or the /D switch with this parameter, (path )is
- ignored, and DT tests the entire disk and all files on it.
-
-
- (filespec) The name of the file or files whose clusters you want to test.
- If you include either the /B or the /D switch with this
- parameter, (filespec) is ignored and DT tests the entire disk
- and all files on it. The default (filespec) is *.*. /B Tests
- the entire disk (/D) and all files on it (/F).
-
- /C(n-) Marks cluster (n) as unusable.
-
- /C(n) Marks cluster (n) as usable.
-
- /D Tests the entire disk, including system areas and unallocated
- areas.
-
- /F Tests all allocated file areas on the disk.
-
-
-
- /LOG Writes diagnostic output as separate output lines that can be
- directed either to a printer or to a disk file by including
- the MS-DOS redirection character (>) followed by a printer
- name or a filename at the end of the command.
-
- /M Attempts to move data stored in unreadable clusters to a new
- location and marks the clusters as unreadable.
-
- /S Tests all files in all subdirectories under the current or
- specified path.
-
- Notes:
-
- You can stop the disk test at any time by pressing the Ctrl-C (^C) or
- Ctrl-Break (^[) key sequence.
-
- Example: Test the WP directory on drive B, to move data stored in
- unreadable clusters to a new location, and to write the output
- diagnostics to the file (test.log).
-
- Enter: DT b:\wp /M /LOG > test.log
