SYMPTOM

When you attempt to open, delete or rename a file or folder using Windows NT Explorer, File Manager or a command prompt, you may receive one of the following error messages:

<drive>:\<folder> is not accessible
The file or directory is corrupt and non-readable.

The file or directory is corrupt and non-readable.

The file or directory \<folder> is corrupt and unreadable.
Please Run the Chkdsk utility.

CAUSE

This behavior can occur if the file, folder or file system index (Master File Table [MFT] or File Allocation Table [FAT]) is damaged.

RESOLUTION

WARNING: When Chkdsk detects problems with the file system and attempts to repair the damage, data loss can occur. Microsoft does not recommend running Chkdsk with the /f command-line switch unless you have a full backup of your hard disk.

Attempt to repair the damaged file, folder or file system index using Chkdsk. To do so, follow these steps:

Click Start, and then click Run.

In the Open box, type chkdsk /f <drive>:, where <drive> is the letter of the drive on which the damaged file, folder or file system index exists.

Click OK.

NOTE: If the hard disk is large, Chkdsk may take several minutes to several hours to complete.

MORE INFORMATION

Chkdsk saves each repaired file in the root folder as a File<nnnn>.chk file, and each repaired folder in the root folder as a Found.<nnn> folder, where <n> is a number.

For information about how to use Chkdsk, click Start, click Help, click the Index tab, type "chkdsk" (without quotation marks), and then double- click the "Chkdsk Command" topic.
