I tried it in a dell latitude with an nec 5100 and it didn't work. None o my mates have cd-rws. I have 2 old cd-rws: the one that came with the burner (liteon branded), and an old ricoh one for about 4 years which was given to me with data, so I could just erase and continue.
Since it hasn't worked in 3 drives and 2 computers, I was more thinking that I'm doin something wrong.
O yeah, aspi layers are fine in both machines, usin xp pro SP1, and 2k SP4, tried nero 551054, nero6310, roxio6, P4 1.8M. burning anything else is fine, including 2 older cd-rws. burns all dvds and cds fine, so the drives work.
