Two questions here:

1.Can CloneCD and Alcohol 120% can be installed together but without any conflict?

2.I just bought a dictionary called “Longman Dictionary Of Contemporary English”(2CDs),I would like to make a backup to keep original disks no damage,using CloneCD,I can get available disk for installing,but cannot pass its validation;So wanna try Alcohol.But don't know how it will be before trying.

P.S.:ClonyXXL cannot find what protection this original disks takes,any new powerful tool for checking this?

Any help or suggestion will be greatly appreciated!

1. Yes !

2. Searcg bei google.com to a-ray scanner

Thank you,sir.

In fact,I tried A-Ray,protectID,etc,none of them can find what protection was used on these CDs,it seems its protection is so powerful.

I burned at least 20 pieces of CD-R,none of them can work.So,I have to give up and the best way is to keep original disks well.
