Eac and the accurrip dbPowerAmp both calibrate your burner's read/write offsets based on reads from official CD's. I'd see no point in putting out a prog that gave just a semi-accurate copy,and personally I had so much hassle trying to get EAC to do SOMETHING useful-I quit caring. My thing now is I use Accurip,if it ain't "perfect enough"...then just move along-nuthin' here for ya.
I recall a record through errors checkbox or such. A damaged disc is a damaged disc and you likely will not get an "exact" copy of whatever bits can't be read. Some CD-R/CD-Rom drives read imperfect discs better. Most read a bit better at lower speeds.
