Thanx to those that replied.
I reinstall Nero 5572 as 1st time install instead of an upgrade it now sees my 24x at higher than 2x. It must be a bug in Nero. I figured it was a sw problem when CloneCD an Cdrwin both saw it correctly as a 24x writer. I’ve since made back ups of 3 games, Hitman- Cod47, MDK2 and HL_Opposing Force. It took over an hr. to read hl_O-F but it did a perfect copy. I’m very, very happy with my 24102b, MY plextor 1210a which I paid more that dbl. for less than a year ago could not back up these games.
Thanx to everyone who shares their knowledge on the forum.
