LeftHand, how to write to a snapshot

I'm a relative newbie to working with the P4000s so I am cutting my teeth with the VSA appliance.

I am testing how snaphots work, and I have successfully taken and connected to the snapshot by adding in the new ISCSI name of the snapshotted volume in the windows iscsi initiator. I have assigned the server read/write access as well, and the disk is available in computer management etc. All good, however when i try to write a file to the snapshotted disk, I get an access denied error. I've done a google, and some folk say snapshots are read only, but I am confused by the fact that I can assign a server read/write to access to the snapshot, this implies that I should be able to write to it!

Have I done something wrong or is this the way it works. And if so, is there a sneaky way I can get write access to the snapshot?
