MORE INFORMATION

Using CHKDSK /f

The steps for using CHKDSK /f are:

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.

At the first screen, press ESC to go to the command prompt.

Insert the disk that contains the CHKDSK.COM FILE into drive A.

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.

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
