The answer was actually simple to fix.......

I changed permissions to the block device & everything now works okay.

I just wasn't sure that changing permissions to block devices, would not cause
problems.

I would however, be interested in knowing the possible cause of why these
permissions should have changed since the original OS install. Netbackup is
the only thing I can think of !  If anybody knows of any possible reason, then
drop me a line & I'll provide another summary.

Many Thanks

Andy Hardy
