Problem with extracting ripped ISO files - "unexpected end of archive"

[southmoor]

Once I have waited hours and ripped the files from the DC to my PC using the serial slave upload method, when I try to extract the ISO images with Winrar, the error "unexpected end of archive" message occurs. When I try to extract the ISO files with Winzip the error "unexpected end of file encountered" occurs. Why? Since purchasing the serial upload cable, I have only tried to rip two games, they are S**a Rally 2 and NBA 2000 and I have encounted this problem with one file from both games.

Someone please help as once I overcome one problem, I seem to come across another.
