not from this snippet, the illegal request implies media/drive issue.
what happens if you try a different media in your drive? maybe a media 
you have
successfully mounted before?

if it were selinux, i think you'd see an error in /var/log/secure or the 
setroubleshooting app.

see how it chokes on block errors? any chance there is dirt or a smudge 
on the media over those tracks?
