Hi List;

I've followed these instructions to get my slow second drive issue fixed. It 
seems to have worked. However now I can only mount the cd/dvd (with the dvd 
drive in the 'ultrabay' as root by explicitly mounting the drive.  My KDE 
automount prompt no longer appears, etc...

Thanks in advance
