Why do I get the following error? (23): Data error (cyclic redundancy check)

This is a Windows error (number 23 as shown) and means you have file or disk-based corruption issues, which need urgent investigation. The error will also almost certainly arise if you try to copy the file using Windows Explorer.


This article has more details.

Note that the error may be on either source/left or destination/right, unless either of these is a non-Windows resource such as FTP, in which case it will be on the 'other side', as it is not possible for a non-Windows resource to return a Windows error message - ipso facto, the error is coming from the side where Windows is 'involved'.

It is quite possible you also see the Windows error 1392: "The file or directory is corrupted and unreadable" in such circumstances. The reasons will be much the same - disk or folder\file corruption.
