Alert: Issue with Canon 1D and 1Ds RAW files on Windows Vista
There is an issue with Canon RAW files that end in .TIF (which are limited to 1D & 1Ds cameras) on Windows Vista systems that do not have the Canon RAW codec.
If a user adds metadata to one of these files, using the Windows Photo Gallery or the Windows Explorer, the file will be corrupted. This is a result of the Windows Imaging Component API not understanding the difference between a legitimate TIFF file, and a Canon RAW file with a .TIF suffix.
Microsoft and Canon have identified the issue and are testing a patch to address the problem. We will provide download information once the patch is released.
