Cyclic redundancy check errors are common when you try to read data from a damaged or failing CD, DVD, hard drive. Usually the computer becomes less responsive and you hear repetitive disk searching noises for up to a minute. And then if you are using Windows XP, you will find a message stating that it cannot be copied because there is an error with the data (cyclic redundancy check). Then the copy process is aborted with no option to retry to read from the damaged area or skip that area. This is very frustrating when copying large files because you have to try to copy again from the beginning. Follow these steps to copy a file from a damaged disk.

Advice

  • When copying a large file that fills the entire CD you can use JFileRecovery to get an understanding of the location of the damaged region of the disk. CDs are written from the inside out. Use the diagram in JFileRecovery to determine the location and focus on removing scratches from that region.
  • You can try to read the damaged regions of the CD again after cleaning.
  • Note that only one file can be uploaded to JFileRecovery. There is no way to select or queue many files for a move or copy. This limitation means that JFR is appropriate to use when you know that there are 1-3 files with problems but if there are many it would be a very tedious process.

Warnings

  • JFileRecovery is a program written in Java. If you don't have Java installed on your computer, it won't work.
  • This technique should only be used on multimedia files such as music and videos and not on executable files. A few bad bytes in a music or video file could cause a minor glitch when playing. But a single bad byte in an executable file could lead to the program not working or even going haywire and causing other problems.
