XP/NT Error in Event viewer

[Xray]

I'm running a Aopen AX6BC bx mobo and a 650 PIII not overclocked.
Liteon 16/10/40.

Im getting this Error message in the event viewer about once or twice a day.

Whats up with this? Its the CDRW trying to write to which port and why?

I think it has to do with memory ranges that are allowed to be written. I would try to figure out what uses that memory range (maybe in computer management) and also possibly be that it is trying to use memory allocated to the NT executive.
