Whenever I try to copy certain files from a CD I get an error which states, " Data cyclic redundancy error" A similar error also appears in Floppy disks.What does this error mean. I think the Cd has started getting spoilt. Is it possible to do away with this error and recover the data from the CD. Its a big file and which nearly completes copying and at the last 5 seconds it gives the error and exits. Please help me.
