MS06-049 / KB920958 causes data loss

Problem confirmed by Microsoft Support:
"We are aware the issue you are experiencing. A corresponding bugcheck request is currently open, and the develop team is working on this issue. However, the hotfix for this issue is not ready. 0xDF is the data pattern that NTFS returns when it has problem to decompress the file (eg. the compression fragments are corrupted and can't be decompressed). Based on my research, the actual raw data on the disk is not changed, it shows as 0xDF because the system cannot decompress the file and display the data correctly. So the corrupt is not permanent. Further more, the issue only occurs on files which containing Hexadecimal codes."
