Hi Dark63 and welcome to the forums. :flower:
It won't be any region code initially.
The first time you play a disc the region code will be set and every time you play a different region the drive's region code will change up to a maximum of usually 3-5 times.
This is probably what has happened to your existing drive and you've used up your allocated number of changes.
Rather than replacing the drive, a cheaper alternative would be to go down the software route and run a memory resident program such as DVDFab Passkey which will make all discs seem region free.
There are freeware alternatives that we can't discuss in the DVDFab forum but if you want details let me know and I'll move the thread.
