SCANDISK: General
How
to Cause ScanDisk for Windows to Re-test Bad Clusters
By
default, ScanDisk for Windows (Scandskw.exe) does not test clusters
that are marked as bad in the file allocation table (FAT). This behavior
applies for both compressed and un-compressed drives and is consistent
with the behavior of the MS-DOS ScanDisk utility (Scandisk.exe)
included with MS-DOS version 6.x and Windows
95.

Disk
Tools Run by System Agent Pause for User Input
When System
Agent runs one of the disk tools (Compression Agent, Disk Defragmenter, or
ScanDisk), the tool may pause for user input. Typically, the tool
is prompting for the drive on which it should run, or is waiting for you
to click the Start
button.

ScanDisk
Errors on IDE Hard Disks Larger Than 32 GB
If you use the
protected-mode (graphical) version of ScanDisk to perform a thorough scan
(which includes a surface scan) on an integrated device electronics (IDE)
hard disk that is larger than 32 gigabytes (GB) in size, ScanDisk may
report errors on every cluster after approximately cluster number
967,393.

ScanDisk Command Line
Syntax Scandskw [drive:] [/A]
[/N] [/P]
scandisk drive:\dblspace.nnn
scandisk
drive:\drvspace.nnn
Parameters
drive: Specifies
one or more drives to be checked.
/A or /All Checks all local,
nonremovable hard disk drives.
/N or /NonInteractive Starts and
closes scandisk automatically. However, this switch does not prevent
scandisk from stopping to report errors found on the drive.
/p or
/Preview Runs scandisk in Preview mode, where it reports and seems to
correct errors that it finds, but it does not actually write changes to
the disk.
Important: When running Scandskw in Preview mode,
it appears as though scandisk is fixing errors, but it is not. Also,
notice that unlike other settings in scandisk, the /Preview switch is not
saved in the Registry, so the next time you run scandisk, it is no longer
in Preview mode.
To determine whether scandisk is running in
Preview mode, look for the tag "(Preview)" in the caption of the main
scandisk window.
dblspace.nnn or drvspace.nnn
Checks the
specified un-mounted DoubleSpace or DriveSpace compressed volume file,
where nnn is the filename extension for the hidden host file.
The
following table describes the codes provided when scandisk finished
running.
Exit code Description
0x00 Drive checked,
no errors found
0x01 Errors found, all fixed
0xFA
Check could not start - cannot load or find DSKMAINT.DLL
0xFB
Check could not start - insufficient memory
0xFC Errors found,
but at least some were not fixed
0xFD At least one drive could
not be checked
0xFE Check was canceled
0xFF Check was
terminated because of an error
You can capture the exit code in a
batch file to define an action to take in the event of particular exit
code. For example:
start /w scandksw c: d: /n
if
errorlevel exitcode goto command
...
In this sample, start
/w forces the batch file to stop and wait for Scandskw to finish
(otherwise, because it is a Windows-based program, the batch file would
continue as soon as Scandskw had been launched). Also in this example, if
the actual exit code is greater than or equal to the exit code specified
by exitcode, the batch file runs the specified command; otherwise, it
continues to the next line in the batch file. The goto command entry could
specify any command you want.
