Error 433 when backing up

Hi, I encountered an error today when backing up a file from an internal drive to a USB SATA interface with a SATA drive connected. For the most part it works fine, but today BVCKUP 2 gave me the error CreateFile() failed with 433.

What does this mean? Any way to avoid this in the future?

I appreciate the help! Take care and Merry Christmas!

433 is not documented as a Windows API error code [1], but apparently it stands for ERROR_NO_SUCH_DEVICE. As far as the cause goes your guess here is as good as mine. Could be a faulty connector, could be a firmware bug causing the drive to shut down, etc.
