CD cannot copy copy hint: Data error (cyclic redundancy check) solution

have been wrestling with a CD these days, because some of the data on the CD can not copy, always appear "cannot Replicate: data errors (cyclic redundancy check)" This error, the Internet to find a lot of ways, said with WinRAR, said with data recovery, said with IIS rack Server breakpoint continued transmission, basically not a reliable, Finally found a way to solve this problem. That is, using UltraISO to make the CD into an ISO image file is OK.

1. First download UltraISO (green version of the online, single file version of a lot of, casually under the bar)

2. Open UltraISO, select File-Open CD

3. If only a few files, then you can directly in the UltraISO to select the file you need, right-click-extract to the specified location on it

4. If you want to get the whole disc out, then you can choose the tool-make the image file, to make ISO

5. Then is the long waiting time, and so on, your ISO basic also finished, with virtual CD-ROM loading or WINRAR decompression Look, your document has been saved.

PS: Because of errors on the CD, the extraction of error files or the production of ISO, time is relatively long, I get a dvd,3 a g of the video file error, it took about 15 hours before the production of ISO, so students have to wait patiently oh.
