Cannot create disk in Hyper-V greater than 2Gb

Hi folks,
I have a curious issue which could just be more not being familiar with aspects of Hyper-V but the problem I have is I need to create a VM for a storage server with 4Tb+ of data.  I can create the initial server ok, with bootable IDE based disk - but I cannot add a second disk due to two reasons:-

1. When creating the disk image file, I only get the option for .VHD files not .VHDX (think thats the right types, but you know what I mean)
2. Creating any kind of second disk fails with either a file already exists error or readonly.  The file itself is created but just doesn't seem to get attached in hyper-V manager settings for the VM in question.

I also cannot find the convert to .VHDX option, so wondering if I've somehow got an older version of Hyper-V and not the newer V3 one...but have downloaded from MS again and performed in place upgrade, but still no joy.

What am I missing???

Cheers
Allan

file already exists error that means file is already created but not attached on the  vm..

greater than 2Gb or 2 TB?

Sorry, I meant 2Tb!

When I try and follow the Petri article, I don't get the same screen options.  Screenshot attached.  Is this maybe just an outdated Manager that is the issue?  If so, how can I check relevent version info on both Hyper-V Core itself and Manager to make sure they are both V3 enabled?

I'm using Windows 7 SP1 64 Bit with RSAT to manage Windows 2012 Hyper-V Core Setup.

Just thinking....is it because I'm managing from a Windows 7 machine and not a Windows 8 one that is the issue here?

By jingo - success!  Think this maybe a RSAT on Windows 7 issue then.
Thanks for your suggestion takecoffee...which is what I will do.

Flat white here we come....

yep Win7 is till using old hyperv Manager console.. glad vtutilites worked for you

please be inform trial period is only for 7 days so you need to install Win8 Os and enable hyperv manager console on that.
