NEC ND-7550A was recognized as DVD-RAM Disc in XP

One day, I suddenly found I can’t burn CD and read CD/DVD with my NEC nd-7550a (but can burn DVD successfully and the disc can be read in other CD/DVD rom).

I searched the web and had tried many ways to solved this problem ( like reinstall driver, update firmware…), but still not work.

I notice windows xp recognize it as “DVD-Ram disc”, it seems abnormal.
does anybody have idea of it?
