Can't connect any of my appvms to my 2nd internal drive?

[Gaiko]

I can access my second drive via thunar in dom0 but at first it would connect to the appvms (vm manager attach device) but not show up via nautilus or be able to mount it manually (actually at first, at least a week ago, I was able to attach and then access via appvms this drive), now on the vm manager the attach devices option is greyed out and I can't select a device at all, the only device to select would be the hard drive but I can't select attach it to any of the appvms but I can still access it and its contents via dom0... I got nothing, help would be appreciated.
