cyclic redundancy check has something to do with your CD drive. I used to have that problem when copying from my crappy old CD-R - best advice to eject and re-insert the disk

CRCs check for errors on your CDs/hard discs etc. It makes sure the data being read is the exact data that was written. During writing, it calculates a checksum for a chunk of data.( Which is really neat how it calculates the checksum (finite field/Galois field arithmetic).)

When it comes to the reading, it does it again and if the checksum is different you have an error.

So there could be so many ways something can go wrong in the writing and reading process of your disc. Could be a faulty/damaged DVD, dirt in the writer/reader, bad writer/reader. List goes on and on.
