I'm cyclically redundant

I was recently trying to import some stuff I'd burned onto CD-Rs (AVI files, uncompressed, 2-3 minutes long each), and most of them worked fine, but two or three of the CD-Rs gave me a problem, saying that I couldn't copy so and so file to the HD because of cyclical redundancy error. When I try to play these files off the CD, the windows media player window comes up, and the video stutters along as it tends to do when you try to play an uncompressed AVI right off a CD (at least on my PC), so it seems the CD-R is okay. Why won't it copy? Anything I can do?

Your file is corrupt. That's what the CRC error is telling you.

Try making a copy of that disc on to a new CD-R...keep the burn speeds a bit slower. Then try to copy the data to your HD from the newly burnt disc.

Or try burning a new CD from the ORIGINAL file.

Yeah. . .the problem is no longer have the originals. . .I'll have to find someone who does. Thanks for the help though.

Can you control burn speeds in Window's default burn tool?

I'm not sure- don't you have Nero or some other sort of burning software.

The same error occured in one of my files and I chose this path to fix it. Apparently, for me at least, it wasn't a corrupt file- at least it doesn't appear that way beings the copy CD transfered fine to HD. Maybe something went aray during the buring to the original disc. If your media player can play the file then more than likely buring a copy then moving it to the hd should work.

However if the file itself is corrupt, like Edward mentioned, your stuck. Garbage in garbage out. You'll simply copy the corrupted file to a new disc. Then you'll have TWO wasted discs. Good luck!

In my experience, my CD drive is not very good so it'll see cyclic redundancy errors while better ones will not. So I try a few different CD-ROM drives to see if I can rescue my files.

2- Some programs should read the CD and ignore errors. If you're lucky you may only have to contend with a few dropouts or something.

3- You can try cleaning the CD with lens cleaning tissue + alcohol or something like that (on the bottom side). Other things can cause scratches to your CD so avoid them.
