Currently the config is: 1st IDE master - hard drive 1st IDE slave - empty 2nd IDE master - dvd/cdrom player 2nd IDE slave - cd burner <-- this is being replaced.

the only commnet I will add to the above is that the DVD should be installed as the Primary SLAVE and not as the Secondary Master.
Reason: the nature of IDE/ATAPI protocol is such that you cannot read and write at the same time on the same IDE cable/connector. So, by having the above setup, with the DVD as master and the CDRW as the slave on the same cable the RW from anything on the DVD is not as fast as it could be.
Of course, by moving the DVD to the slave position on the primary cable the information in the /etc/fstab file will need to be amended -- and you do this BEFORE powering down to install the new RW and re-position the DVD. Or you can do it later, but it's more fiddly. Oh, you would also install the new CDRW as the master on the secondary cable (unless you want to avoid this by installing a new, second, HD on the 2nd cable as Master :-) ).
Thanks Dylan. It may be an urban myth, but I was always under the impression that it was unwise to mix hard drives and cdroms on the ame IDE cable? The only "price" I pay for the current setup is that I rip to hard drive and burn from there to cdr/rw. I believe that is better anyway to avoid potential 'coasters'. What if I wanted to add a 2nd hard drive later? In your scenario, it sounds like /etc/fstab is the only change + redo the k3b setup (re-detect) after coming back up I presume? Paul.
