Copy to Removable Drive in Explorer May Fail After Media Swap

• Microsoft Windows NT Workstation version 4.0
• Microsoft Windows NT Server version 4.0

SYMPTOMS

In Windows NT Explorer, when you drag a folder from your hard drive to another folder on a removable drive, the files do not get copied correctly.

This problem only occurs when:

• You have recently changed the media in the removable drive but have not forced an update in Windows NT Explorer by pressing F5.

  -and-

• You are dragging files or folders to a folder that used to exist on the previous disk, but does not exist on the new one.

CAUSE

This problem is caused by a problem in the Explorer.exe code in Windows NT 4.0. The problem does not occur in File Manager (Winfile.exe) in Windows NT 3.51 or 4.0.

WORKAROUND

To work around this problem, force an update of the Windows NT Explorer window by pressing F5 after changing the removable media.
