When you (or anyone reading this) decides to buy the LATEST drive available, it is wise to contact us, or post in this forum BEFORE you buy.
To come back now and say you are really chapped...
gee whizz, is that MTU's fault? 
We can't spend our time posting all over the web site what we HAVEN'T done that someone might want us to do.
However, we willingly answer any questions.
What the heck! I'll just have us do a release with the new Plextor drivers early this week for 2.605 and ignore all the other things we were going to add. That way, you and a few others can get on with using your new, unsupported drive, and we can say we are supporting it.
Yep! That's what I'll do. It just doesn't make sense to sit and take it on the chin when we are not at fault, but could meet your desires anyway. We'll do that. I hope you appreciate it.
And... next time, ask before you buy. Everyone here will be more than willing to give you guidance... so you won't get chapped at us.
