I have a back up DVD that I cannot mount. dd won't read /dev/acd0 with an error dd: /dev/acd0: Input/output error.Tried dvdisaster but it can't find my drive. Any pointers you can offer in getting this data off this disc are greatly appreciated.

A tiny, unauthorive FAQ is what you're supposed to follow. http://www.freebsd.org/cgi/query-pr.cgi?pr=149020 On the other hand, you miss understand what dvdisaster is capable of. It will not help as you're supposed to use it BEFORE it goes bad. I would try Chuck's suggestion first then maybe some physical media repair techniques. Are you sure the DVD was ever usable? -- Adam Vande More ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
