just make sure it is set to either slave or master on the new one to match the one that was removed. and the red strip on one side of the flat ribbon cable always goes next to the power connecter.
Nothing to worry about when it comes to drivers either, just remove one and put the other one back in it's place turn on computer and it will sort everything out automatically.
keep in mind that windows can only write to CDRs with out extra software though so you will need to install some DVD writing software if you want to make DVD's
Just thought I`d let you know, I managed it ok. It`s a friends computer, it only had a cd player in, couldn`t record to it even.
I had a non working computer with a decent Pioneer DVD RW, so I`ve put that in.
Couldn`t work out how to set the jumper though, but went ahead, it`s working great, so luckily for me it must have been set same as the cd one.
Thanks again for the advice.
