An unexpected error occurred while updating files

Unfortunately, as technology progresses and the horribly outdated FAT32 file system continues to be used, issues will arise more often.

For example, copying large files to an external drive in Mac OS X might lead to the following Finder error: “The operation can’t be completed because an unexpected error occurred (error code 0).” Before cursing your Mac, it’s important to note this is an issue with FAT32 that Linux and Windows users experience as well.

The component attempted to make a cross-context call between invocations of Enter Transaction Scope and Exit Transaction Scope. Cross-context calls cannot be made while inside a transaction scope.

An attempt was made by this server to make a Kerberos-constrained delegation request for a target outside the server's realm.

Most values also have a default message defined, which can be used to map the value to a human-readable text message; when this is done, the HRESULT value is also known as a message identifier.

You should also search the Microsoft Knowledge Base for more information about the error.

The cause is FAT32’s 4GB limit on individual file sizes.

So while your drive might be 160GB in total, no single file can be larger than 4GB with FAT32.

“The operation can’t be completed because an unexpected error occurred (error code 0).” If you received this message when copying files from your Mac to an external hard drive or USB flash drive, there is a simple explanation.

Most external hard drives and USB flash drives, unless they are specifically marketed as Mac products, are formatted with the FAT or FAT32 file system.
