    Based on that error, and that writing works OK, I guess that your
    configuration is fine, but the reading bit is broken. I had a similar
    experience earlier this year with an Acer 16x16x12 CD-ReWriter. Reading
    worked perfectly, but any writing activity would spit out IO errors all
    over the place.

    I think - take with a large grain of salt - that the CD drive has
    separate lasers for reading and writing, and the read laser maybe
    stuffed. IANAHWE (I am not hardware engineer).

    Regards
    Edward
