could be the reader then? Do you have another computer with a dvd drive and 4.7g available space? these things are fiddly, there are billions of little holes and a laser light reading them. There are manufacturing tolerances in the reader and the disk. There are imperfect firmwares in the drives. In short, sometimes a particular disk and a particular drive just don't get on. The drives also get old and tired. IMHO you need to be prepared to throw the drive out after some indeterminate (but not long enough) period and get a new one. Is this a movie or data? Have you tried just mounting then copying the files to your hard drive. This might identify where on the disk things are going wrong. If it is a small or unimportant file you might still have an effective backup. -- Nick Rout <[EMAIL PROTECTED]> -- gentoo-user@gentoo.org mailing list
