SYMPTOMS

If a Microsoft Windows CE .NET device suspends while a file copy operation is in process to an external file allocation table (FAT)-based storage device, such as a Compact Flash (CF) card, a problem may occur. The storage device may lose clusters after the file copy operation resumes.

CAUSE

When the Windows CE .NET device suspends, all pending sector-write operations are stopped. When the sector-write operations resume, the drivers for the storage device unload and then reload. These file operations cause an error. When this problem occurs, the unwritten sectors are discarded. However, the file copy code in the shell detects the file-write errors and then deletes the files. This removes the directory entries for the files and leaves the FAT allocations on the disk as they were before the file copy operation suspended.

RESOLUTION

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

MORE INFORMATION

Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

This problem occurs because of the behavior in the CopyFileEx() API of the shell. The CopyFileEx() API of the shell immediately deletes the file that the CopyFileEx() API of the shell did not copy. There are also complex timing issues in the file system and in the device manager.

To implement a fix that carries the least risk, this hotfix changes the behavior of the CopyFileEx() API to skip removing the failed file. By default, this change is not enabled. To enable this fix, the OEM must include the following registry setting in their operating system:

[HKEY_LOCAL_MACHINE\System\StorageManager] "DeleteOnFailedCopy"=dword:0
