I would however like to extend what you noted. Many of the older (greater than 3 years) cdrom drives I've tried don't recognize anything BUT a 650 meg cdrom. Around here I haven't seen anything but 700meg blanks in a while. I've also found that a great way to ensure a non readable cd is to create it with CD-Creator and an older hp 4x burner. Not even windows can read many of them. (except of course on the box that burned them.) I've got a friend of mine reburning about 200 cdroms (data moved off of a ton of mag tapes) due to this combo. In fact my 7.1 disks from Mandrake..... I've got an 4x that won't read them. EVERYTHING else does.... but not this one creative drive. (one of the old cartidge type.) James > > > > >
