Samsung hd502hi review pinout

I have just bought a samsung hd502hi. I am trying to find the jumper settings for master / slave configuration. The little manual that comes with the disk and the web site documents (which are the same) refer to a diagram that looks like an IDE version of the disk and not the SATA version that I bought.

Can any body tell me which is pin A on the Master / Slave setting? There doesn't appear to be any marking on the disk to indicate Pin A.

Thanks
