Yes thanks has been working fine since. Should really be a sticky or help relating to this directly for the error.
Bet it has caused a lot of headaches to people running older Server OS.

Appears to be working up to 200gb now where as previously would have not got this far 300gb to go fingers crossed.

Wow interesting article, cant believe they haven't fixed it in Server 2012R2. I would have never found that.
I will have a go at this and let you know on the outcome.
Thanks
