majagua, At the present moment I am in the process of reformatting a HDD. The first clue I had that something was wrong with this drive was CRC errors when trying to burn a CD-R in Nero. I eventually traced this to read errors on the HDD (a Maxtor), and upon running the appropriate vendor diagnostics discovered the drive was faulty and needed to be replaced. Maybe there are other reasons for CRC errors, but at least consider the possibility that they are HDD related and not necessarily indicative of something wrong with the burner and/or burning software.
