                     Running CHKDSK for OS/2 Warp
=======================================================================

--------------------------------------------------------------

DESCRIPTION

You should run CHKDSK on a regular basis as a maintenance process. It 
is most effective when run from diskettes.

RESOLUTION

You do not want to interfere with the Swapper. The CHKDSK command 
should NOT be issued when OS/2 is started from the hard disk, because 
the SWAPPER.DAT file is in a constant state of change, and CHKDSK might 
provide misleading results. CHKDSK might require several passes, 
because it cleans up primary structures first, and then cleans up 
secondary structures.

The CHKDSK command with the /F parameter is used to correct disk and 
directory errors. When you use the /F parameter, no activity occurs on 
the disk. Therefore, if you need to correct errors on the drive from 
where you start OS/2, you use the version of CHKDSK on the installation 
diskettes or CD instead of the version installed on the hard disk. 
Also, use the version of CHKDSK on the installation diskettes or CD if 
the disk is in use or locked by another process.

Procedure
---------
1. Shut down the system. If you're unable to shut down, turn off the
   system for 30 seconds.

2. Insert the Installation Diskette in drive A.

3. If you performed a shutdown in step 1, press Ctrl+Alt+Del to restart
   the system. If you turned the system off, turn it on.

4. When prompted, remove the Installation Diskette and insert
   Diskette 1.

5. Press Enter.

6. When the Welcome Screen appears, press F3 to display the command
   prompt.

7. Remove Diskette 1 and insert Diskette 2, which contains the CHKDSK
   command.

   Note: If you installed from CD:

     a. Insert the CD into the CD-ROM drive and press Enter.
     b. Type x: and press Enter (x is the CD-ROM drive).
     c. Type OS2IMAGE and press Enter.
     d. Type CD DISK_2 and press Enter.

8. To correct errors on the hard disk, type the appropriate CHKDSK
   command, as follows, and press Enter (x is the drive where OS/2 is
   installed):

   * For FAT file system:  CHKDSK x: /F
   * For HPFS:             CHKDSK x: /F:2

   Note: If you have any errors, continue to run CHKDSK until all
         errors are cleared up.

9. Remove the diskette; then press Ctrl+Alt+Del to restart the system.
