OS/2

Summary:

PROBLEM ID: OS29012008

SYMPTOMS While formatting a logical drive as HPFS, if CTRL+ALT+DEL is pressed for a warm reboot, the system hangs and the following message is displayed:

You are attempting to use an incorrect version of HPFS.DLL. Press enter to continue. This error message should refer to UHPFS.DLL instead of HPFS.DLL. If LAN Manager is being used, the message correctly refers to UHPFS.DLL.

Any subsequent attempts to format the drive as a FAT drive result in the following messages being displayed:

Formatting has completed.

SYS0026: The specified disk or diskette cannot be accessed. NOTE: This problem does not occur if the drive is originally being formatted as a FAT drive and CTRL+ALT+DEL is pressed.

RESOLUTION/STATUS To work around this problem, reformat the drive as HPFS and then format it as a FAT drive.

Microsoft has confirmed this to be a problem in OS/2 version 1.21. We are researching this problem and will post new information here as it becomes available.
