Explanation:  The compressed file has been corrupted on the disk. During decompression, the integrity of the data describing the compressed file is checked. If any of the checks fail, data corruption is assumed, and compression cannot be completed, as is the case here.

Possible Cause:  This error can only be caused by the data changing on the disk. Changed data can result from one of the following causes:

• Magnetic or electronic media close to the disk drive
• Failure of the disk drive or supporting hardware

If the disk drive is failing, other files will be corrupted and will not contain the original data.

Action:  Try restoring the file from an earlier backup. If you cannot restore the data from a backup, the file is lost.
