You didn't say what kind of 3590 drives or tapes you are trying to use,
or the microcode or device driver levels, which may be a factor.
The Messages manual guides you through fact-finding... CC=404 talks of
media incompatibility; Key=03 is a media error; ASC=31 is media format
corrupted.  Are you like trying to use K cartridges in a 3590B drive?
If this just started happening, look for media, microcode, hardware,
device driver, or other changes in your environment to incite this.
You may have to confer with your hardware support people.
