Copy from DVD - Input/Output error
About 2 months ago I burned some data on a linux machine running Redhat to a DVD. Now I'm trying to get some of the data off. On the disc there are 7 folders, all containing the same type of data (although not duplicates of each other). With all of the folders but one I can copy the data off the DVD without a problem. However, with one of the folders I can't copy any of the files, instead I get the following error:
cp: reading '<file>' : Input/output error
I've also tried copying the files on a PC running Windows XP and again I can copy every folder except one, and when I try and copy a file from that folder I get the following error:
Cannot copy <file>: Data error (cyclic redundancy check).
Does anyone know what these errors mean and why I'm getting them? Also, is there a way I can get at the data on the DVD (it appears to the correct size on the DVD)? Thanks very much.
