I just got a hr34 hooked up Monday and I'd like to add a external hd to the unit. I have a 1tb drive that I used with my dish 622 and the dive has an e-sata port. I noticed that the HR34 has a sata connection on it. Needless to say my e-sata cable isn't the right size to fit the port. Can I just buy an e-sata to sata calbe and expect it to work? Thanks in advance for the information.
