Kprobe question

i have an 851s drive and a creative dvd drive.
just wanted to know why the creative drive wont work with kprobe.
and nero cd-dvd speed wont work with either.
both apps show both drives but wont perform the tests.

I do believe that Kprobe is for Liteon drives only

Yes, KProbe was especially designed for LiteOn Burners and the results it produces with other burners can not be taken serious.
