Hi Spoon, ok thanks for your reply. Please can you just also answer this question (and I will go away....):

If I add the +667 offset manually and continue using the drive with that offset (for difficult to rip CDs - it has already ripped a CD accurately which only could be ripped as Insecure on two other drives) as long as I get either an Accurate rip or it is Secure?

Many thanks

Nubben
