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