BASF readability

Although discussed extensively throughout this forum that BASF (now EMTEC) cd-r’s are of a very poor quality…I was wondering whether the readability of these cd-r might be affected by the cd-drive. I’ve have important info (1 video file) on two disc in a arj archive (I know I’m a jackass for backup data like this) but both of the have two bad clusters and it is only possible to extract the data out of the arj archive upto the bad cluster. Is there any (!!) way of extracting (some) of the data (f.i. by starting the extraction file after the bad cluster…)

If any of you have a something that could be of assistence pls mail me/reply!
