Data Error (Cyclic Redundancy Check ) and Can't Read from Disc

Today while copying a file from one of my old disc (CD) to my computer I have received an error message and copying failed. The error message is Cannot copy [file name]: Data error (cyclic redundancy check ). When I click OK button, the message window closed and informed copying failed. I tried to copy the same file from the CD again but as I expected the same warning came and the operation failed. This tutorial explains this error with remedy. The below image shows how the message looks in case if you are not familiar with it. I was trying to copy a file named AVSEQ02 from the CD to Hard Drive when I got this warning message.

What is Data Error - Cyclic Redundancy Check

Cyclic Redundancy Check (CRC) is an error detecting code used to check whether the data stored in the storage device is corrupted or not. In my case, it is an old CD and probably corrupted. So PC failed to read the necessary file and the copying process failed.
