With a suitable CDROM drive such as yours and CDs in reasonably good condition, there should be no need for cdparanoia's data correction feature. In fact, I found that it can sometimes do more harm than good, so I recommend disabling it (-Z), if only for testing purposes. You could compare your results to Exact Audio Copy (Windows, free for non-commercial use), which reportedly also runs on WINE. Another option would bei morituri, a CD ripper for Linux modelled after Exact Audio Copy.
