Hi, I have done a search on several search engines and on this site and I can't find information on this anywhere. I have a western digital my passport 250 gb ehd that I have been using for my PC. I would like to use it as an EHD for my bedroom receiver. My 622 does not recognize the ehd. Do I have to reformat the ehd on my PC 1st or is this even possible. I did read on this site that some have had success by plugging this drive into a usb hub. Can anyone help me? Thanks in advance. By the way I have paid for the authorization to use an EHd and I have a 1tb WD EHD on my other 622.
