System error codes will appear in software programs and in various areas within the Windows operating system after certain errors occur.
Unfortunately, sometimes all you get is the system error code but nothing about what the code means!
“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 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 Win32 error code is also known as a message identifier.
The following table specifies the values and corresponding meanings of the Win32 error codes.
Vendors SHOULD NOT assign other meanings to these values, to avoid the risk of a collision in the future.
Once you know what the system error code means (below) then you can work on fixing the problem.
Note: A system error code is not the same as a Device Manager error code, a POST code, a STOP code, or a browser error code, even though the error numbers may sometimes be the same.
