Nec 3540a cd disks problem

Hi,

today my 3540a (1.w5) burner, failed to recognise cd disks, all of them (originals, r, rw). with dvd disks everithing is ok. I’ve installed in another comp and same story. Any hint for this drive to work with cd’s again?

thanx in advance,
abuser.

try firmware 1.W8
but for the most of the time i think you need to return it for replacement
