everytime I try to copy a file from a paritcular CD-R to my harddisk, I will get the reply "Data Error (Cyclic Redundancy Check)".  may I know what is the problem, and does it have anything to do with my CD being scratched?

Maybe. The error is saying that the checksum used to make sure the file copied correctly, is wrong.

Your hard drive might need a scandisk to fix some errors, do a chkdsk /F in command prompt and reboot. That will do a chkdsk and fix errors on your next boot.

I tried to copy other files on the same Cd to my harddisk, and no problem arises.  I tried performing the chkdsk already, but the problem still persists.  Is there any other method?

CRC errors when reading the discs means that there is corruption of a file. The reason there is corruption can vary...scratches can cause these problems. Since it is obvious your current CD-ROM drive cannot copy the file, you have a few options...

I have tried using other CD-ROM drives in the past, with some sucess. Because of varying laser strengths and error correction quality, a high end drive like a Plextor may be able to read a file that another lower-quality CD-ROM cannot.

If the CRC error is due to a scratch, you can try cleaning it, or even better....using disc doctor ( http://tinyurl.com/59w9h ) on it. You can usually pick one up at a local best buy or circuit city. It will resurface the disc and take any minor scratches out. It has made unreadable DVDs work perfectly again for me in the past.

The file is a video file, a divx anime video. The cd is a normal CD-R.  I got the error when I try to read or copy the video.

Hello ghost85;
This problem mostly caused by a bad media (Scratched, dirty CD etc) If the file is a big file, you can probably recover most of the file. I suggest using BadCopy which is commercial and a trial version can be downloaded from
http://www.jufsoft.com/badcopy/
If you can recover this file using this program, and i'm assuming the file is DivX as you said above, you'd probably need to rebuild Avi index to get the file working again. You can try http://www.repair-video.com/ for that issue.
Hope these helps...
