"My Passport WC Studio T2
I cannot find any reference to a WD external hard drive with that name, but there is a WD My Passport Studio 2TB
model. Is that the one you mean? If it is, the manufacturer's support page for that model is here (Install Guide, User Guide, Manual, Knowledge base etc): http://www.wdc.com/en/products/products.aspx?id=420
Hope that helps.
