SYMPTOMS
Disk corruption may occur on DiskOnChip media with the Windows CE TrueFFS drivers. This problem may also occur on other media if the underlying block device driver supports DISK_IOCTL_DELETE_SECTORS.
CAUSE
An error in the calculation of the disk sector number that is passed from the FAT file system driver (FATFSD) to the block device driver during a delete-sector operation may cause the block device driver to clear the contents of an incorrect sector.
RESOLUTION
A supported software update is now available from Microsoft as Windows CE 4.0 Core OS QFE Q321946. To resolve this problem immediately, click the following article number for information about obtaining Windows CE Platform Builder and core operating system software updates:

MORE INFORMATION
Support for the DISK_IOCTL_DELETE_SECTORS operation in block device drivers is optional. This driver control code is used to inform the block device driver that a sector is no longer in use and can be erased.
The ATADISK and ATAPI block device drivers that are supplied in Windows CE .NET for use on the FAT file system on ATA Flash, CompactFlash, and hard disk devices are not affected by this problem.
STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
