If your law states you can make backups of software, the license agreement still is in effect. It supercedes the quaint local laws.
I don't think this is the case, if a license agreement says something that is contradictory to law in the region it is being applied I am sure the law of the land overrules it. This stuff is pretty similar but I am sure no-body minds you making legitimate backups, especially to fix flaws that should not be present, and means they are distributing faulty goods (which I think is illegal).

As for making things worse, your CD copier will read the bad data on the CD a few times and then faithfully reproduce whatever random garbage it happened to read onto your brande new CD. When the Jag reads the perfect copy of bogus data it will never work and Poof! You cannot ever read the CD.
But you did say that some drives will retry a few times and then get it and continue. If this is the case the valid data must be there but take several attempts to read. So by copying it, you offload this rereading delay to a one time only operation of the CD Reader, which once it gets the correct data proceeds also. Then when the new disc is written the correct data is written.
Obvioulsy turning on "Ignore all read errors" would cause problems, but if the Jag can finaly get past it, it is either not required data, or readable (eventually).
