Hi, I upgraded from FC2 to FC4 after being helped by this mailing list to (hopefully finally) isolating machine failure to bad memory (using memtest86 as diagnostic tool). Basically I can't get x-cdroast 0.98alpha15 to work in FC4 yet K3b 0.11.23 works without a problem The x-cdroast trying to blank a cd-rw, says the cd-rw is "busy", retries a few times, then gives up. K3b had no problems blanking the same cd-rw. One of the messgaes given by K3b is that it is unmounting the CD-RW and this may be the problem in x-cdroast - although I never had this "busy" problem with previous version of Fedora. This all seems very strange as I believe they are both front ends to cdrecord - I may be wrong in that idea though. Also writing CD-RW is a whole lot easier to set up using k3b - none of this setup of hard disk directories as in x-cdroast. With K3b, Just drag and drop the files you want on the CD-RW and a little progress bar at the bottom shows how much of the available space on the CD-RW has been used. Press "burn" and it all happens. So far, the change to K3B has been painless and K3b seems easier to use and more reliable than x-cdroast. Strangley, the K3b "system check" indicates cdrdao is not installed and claims this is necessary for cd-writing. I tried a "yum install" on cdrdao but this product was not found. So I tried the burning of a CD-RW anyway without this installed - and it seems to have created a readable CD fine. Regards Clive
