Cannot write to physical hard drive when running UnRAID through VMware

[EpiX]

my set up:

 

I'm trying to run UnRAID on my Windows 7 Box through VMware.

 

After a few days I have everything working except one thing and I ran out of ideas on how to fix it

 

I have a physical hard drive that I want UnRAID to see so i set up the "use physical hard drive" feature that VMware has. 

 

everything works good, UnRAID sees it, I can assign it to an active slot and even start the array.

Then i need to format it... The second i click that button VMware give me an error and it crashes.

 

 

I have gone into disk management and turned the physical hard drive "offline"

I am starting VMware in Admin mode

 

 

any suggestions?

 

Thanks
