be closed for this program to run. If the drive is currently in use, a

message asks if you want to reschedule the disk-checking for the

next time you restart your computer. Your drive is not available to

run other tasks while the disk is being checked.

Scan For And Attempt

Recovery Of Bad Sectors

repair file system errors found during disk checking, locate bad sec-

tors, and recover any readable information located in those bad

sectors. All files must be closed for this program to run. If the drive

is currently in use, a message asks if you want to reschedule the

disk-checking for the next time you restart your computer. Your

drive is not available to run other tasks while the disk is being

checked. If you select this check box, you do not need to select

Automatically Fix File System Errors because Windows XP Profes-

sional attempts to fix any errors on the disk.

Note Check Disk runs in five phases: file verification, index verification, security descriptor

verification, file data verification, and free space verification.

You can also use the command-line version of Check Disk. The command-line syntax

for Chkdsk is as follows:

Chkdsk [volume[[path]filename]]] [/f] [/v] [/r] [/x] [/i] [/c] [/l[:size]]

The switches used by Chkdsk are explained in Table 10-8.

Table 10-8

Chkdsk Switches

Switch Description

filename Specifies the file or set of files to check for fragmentation. You can use the wild-

cards * and ?. This switch is valid only on volumes formatted with FAT12, FAT16,

and FAT32 file systems.

path Specifies the location of a file or set of files within the folder structure of the vol-

ume. This switch is valid only on volumes formatted with FAT12, FAT16, and FAT32

file systems.

size Changes the log file size. You must use the /l switch with this switch. This switch is

valid only on volumes formatted with NTFS.

volume Specifies the drive letter (followed by a colon), mount point, or volume name. This

switch is valid only on volumes formatted with FAT12, FAT16, and FAT32 file sys-

tems.

/c Skips the checking of cycles within the folder structure. This switch is valid only on

volumes formatted with NTFS.

/f Fixes errors on the volume. If Chkdsk cannot lock the volume, you are prompted

to have Chkdsk check it the next time the computer starts.

/i Performs a less-vigorous check of index entries. This switch is valid only on vol-

umes formatted with NTFS.

/l Displays the current size of the log file. This switch is valid only on volumes for-

matted with NTFS.

/r Locates bad sectors and recovers readable information. If Chkdsk cannot lock the

volume, you are prompted to have Chkdsk check it the next time the computer

starts.

/v On volumes formatted with FAT12, FAT16, or FAT32, displays the full path and

name of every file on the volume. On volumes formatted with NTFS, displays any

cleanup messages.

/s Forces the volume to dismount first, if necessary.

/? Displays this list of switches.

Used without parameters, Chkdsk displays the status of the disk in the current volume.

How to Free Up Disk Space with Disk Cleanup

You can use Disk Cleanup to free up disk space by deleting temporary files and unin-

stalling programs. Disk Cleanup lists the temporary files, Internet cache files, and

unnecessary programs that you can safely delete. To access Disk Cleanup, select the

drive you want to check in Windows Explorer or My Computer. On the File menu,

click Properties, and in the General tab, click Disk Cleanup. The Disk Cleanup dialog

box is shown in Figure 10-24, and its options are explained in Table 10-9.
