Quality of computer CDP has nothing to do with it. Get good ripping software like MAX or XLD for Mac or EAC for Windows. Ripping program reads CD as data instructing CDP to re-read given sector multiple times until proper checksum is obtained. MAX (free) that I use allows to set number of attempts. I set it to "Do not allow to skip" that will guarantee that extracted data is identical to original CD. Some ripping programs even allow you to compare overall CD checksum with database.
CDP operates differently - most of them cannot read the same sector twice because they operate in real time. For small scratches within 4mm along the track they error correct it, between 4-8mm they interpolate missing sector and skip for scratches longer than 8mm.
Also notice, that ripped CD is stored on HD as data (no timing).
