I'm running FC4 with all the updates. Generally it works great. I can write DVDs without errors using K3B. However, I can't mount a DVD for reading. Selecting "Mount" on the "CD Recorder" icon on the desktop yields: "mount: I could not determine the filesystem type, and none was specified Please check that the disk is entered correctly." I've tried this with both a Rocky Ridge and Joliet formated DVDs as well as a 3rd party commercial DVD. Double clicking the "CD Recorder" icon yields: Could not mount device. The reported error was: mount: I could not determine the filesystem type, and none was specified Doing it manually: mount /dev/hdc -tjfs tmp mount: block device /dev/hdc is write-protected, mounting read-only mount: wrong fs type, bad option, bad superblock on /dev/hdc, missing codepage or other error Any idea what could be causing this problem ? -- Kim Lux, Diesel Research Inc.
