cannot identify cdrw

[harry_b]

Hi, is there a utility that will identify my cdrw?, it came with a new pc from pc world (everex p4 2gig pc), there are no markings on the writer other than 24x10x40x, i have removed it from the everex pc and replaced it with my liteon ( so the kids can burn cd's ) i now have this one in my own pc but cdrwin etc dont see it as a writer, device manager simply identifies it by the above speed ratings??
