I suggest trying dd. It is a simple command-line utility which will copy
a file byte by byte, and will not be fooled by "bad sector" problems.

Syntax: dd bs=32 if=/dev/hdb of=/home/yourname/file.iso

The "bs=32" tells it to read in 32 bytes and write out 32 bytes, 
regardless of
the junk in those bytes. This will even allow you to make copies of 
filesystems
your system does not understand.
