SUMMARY
Page 389 of the Microsoft OS/2 "User's Guide" explains how to use the CHKDSK /f command to fix errors on the hard drive, but the process is somewhat confusing and can lead to errors. This article explains some potential problems and errors.



Using CHKDSK /f
The steps for using CHKDSK /f are:


 * 1) Insert the MS OS/2 Install disk into drive A and turn on your machine, or, if it is already on, restart it by pressing CTRL+ALT+DEL.
 * 2) At the first screen, press ESC to go to the command prompt.
 * 3) Insert the disk that contains the CHKDSK.COM FILE into drive A.
 * 4) Type CHKDSK C: /f:3 and press ENTER.

Proceeding Without START-UP
Step 3 directs you to insert the START-UP disk, which contains CHKDSK.COM. This disk was created when you installed OS/2. If you can't find it, there are two ways to get around the problem:


 * At step 3 insert the MICROSOFT OS/2 DISK 1 and proceed. - or -


 * Copy CHKDSK.COM and UHPFS.DLL from the C:\OS2 directory to a floppy disk and insert it at step 3.

Errors Caused by Absence of UHPFS.DLL
If the disk used in Step 3 does not contain CHKDSK.COM and UHPFS.DLL, you can receive numerous errors. If it has only CHKDSK.COM, you receive:

Error 1
The type of file system for the disk is HPFS.

SYS1509: The system cannot find the specified program.

This error occurs when you type from the [A:\] prompt: CHKDSK C: /F

Error 2
The type of file system for the disk is FAT.

SYS0118: The specified drive is being used by another process.

This error occurs when you type from the [A:\] prompt: CHKDSK /F

Error 3
The type of file system for the disk is HPFS.

SYS0566: The specified disk is being used by another process.

This error occurs when you type from the [C:\] prompt: A:\CHKDSK /F
