Looking for two RE4 drives in the 1TB size. The Western Digital site shows they manufacture them in the 1TB size, however every vendor indicates they are either sold, out, on order, or can be available in 4-6 weeks. I contacted WD on their availability, but haven't gotten much response except they don't carry them on their online store, and to do thorough web search (which I did). Any pointers of suggestions on where to locate either more information on their availability or where I could get two drives? Thanks in advance.
