Isn't dd_rescue already on the Knoppix CD?
Knoppix is a very big download (although it's a very easy way to get some Linux experience - it doesn't involve modifying your PC by installing stuff on the hard drive, everything runs from the CD). There are a lot of 'live' Linux boot CD's, many of which are much smaller than Knoppix.
I don't know which ones have dd_rescue, but I suspect at least some of the discs in the 'rescue' category will have it.
A bit more research reveals it's definitely on RIP, which is a 25Mb download.
