    over the weekend, i had to reformat my computer cause it was just filled with so much junk.

    i havent been doing a good job backing up my work so i spent quite a few hours burning images on to dvd.

    well most of the images were transferred to the computer safely but one and this is one that i need.

    i keep getting Cyclical Redundancy Error.

    i have tried different computers and i even went back into nero burning software to close the disc which i previously left open.

    but no help.

    am i screwed or is there hope?

    Personally I have not found a solution to this. I have had this problem before. I managed to save most of the data on the disk by finding out the exact file it had the error on (watch the transfer) and then carry on the transfer from the next file after.

    Hope that helps.

    yeah, that's pretty much the best you can do. (If you picked the file apart, you might be able to extract *most* of the corrupt file, but it wouldn't be easy, and probably would be useless)

    I hope I understand your problem right: You can't copy your file from CD/DVD to your harddisk?

    If that's the problem you could try to bypass the crc check and see if the file is still usable for you.

    As I don't know which operating system you are using:
    1. For Linux you can try dd. For example something like this:
      Code: 
      dd if=/mnt/cdrom/somethingImportant.doc of=/tmp/savedToDisk.doc conv=noerror
    2. For windows I'm not sure, but you could try dvddisaster (http://dvdisaster.sourceforge.net/)

    But don't expect too much! Everything you have now, is a corrupted file on your harddisk. But you could try to open/edit it.

    I don't think you are able to repair that file. What specific file format is it? .doc, .jpg?

    One possibility we haven't addressed: is the disc scratched? If so, use a DVD/CD scratch remover and see if that helps. The success rate is pretty good if it's just a blemish in the polycarbonate layer and not the reflective data layer.

    Yeah could be a scratch or it could be that the image just didnt copy properly onto the DVD. If it isnt an important file and you can skip it then see if that works, otherwise you are probably screwed....
