Hi Paul, > Is is safer to remove the old rpm and then install the new one. Noted with tks. > Are you sure that your disk is not damaged? I have a FC5_64 box newly built with a Sony DVD Writer DRU-820A installed. Performed following tests; 1) Burned TDK DVD+RW on FC5_64 by running K3b. Failed alwasys complaining no media on the tray. Ran; $ growisofs -dvd-compat -speed=4 -Z /dev/dvd -R -J -pad /path/to/directory It worked erasing the DVD first then burning all files on the directory. $ dvd+rw-format -lead-out It worked without complaint but the content on DVD not erased $ dvd+rw-format -blank It did not work and complained 2) Moved the NEC DVD Writer ND-3570A from FC3 to FC5_64 box Burned TDK DVD+RW by running K3b. Failed alwasys complaining no media on the tray. Ran; $ growisofs -dvd-compat -speed=4 -Z /dev/dvd -R -J -pad /path/to/directory It worked erasing the DVD first then burning all files on the directory. $ dvd+rw-format -lead-out It worked without complaint but the content on DVD not erased $ dvd+rw-format -blank It did not work and complained I suspect whether it is the problem of K3d on FC3 box being out-of-date.
