Chris and Kam,

Thanks for your reply.  

I was not removing anything from the CD/DVD drive that I recognized even
by way of an unmount command.  I did have a couple of discs in each
drive, one with music and the other with data.  

Part of the problem I have is that I am not quite sure where /dev/hdd/
is.  I have /dev/hda, and /dev/hdb as hard drives and I presume /dev/hdc
and /dev/hdd are the 2 CD/DVD drives on the system, but I am not sure
how to identify the driver with the CD.  

I did install smartd from the yum repositories by way of smartmontools
and have done a disc check on /dev/hdb without having errors reported.
It looks to me that most of my problems may be on the CD/DVD drives.

Any suggestions would be appreciated.
