Clubland X-Treme 2

I’m using CloneCD v4.3.2.2 and i’m making a backup of this album.

Its not a problem…yet. While making an image file of the 2nd CD, between certain tracks, its showing ISRC [a series of letters n’ numbers].
My question is, does the ISRC affect me making a copy of the 2nd CD? I’ve never come across this before til now…

Don’t see why it should. So long as ccd can read the cd and you use a profile that reads the first session only (assuming that it’s copy protected, standard Audio CD profile is fine), you shouldn’t have any particular difficulty in making your back-up.
