I purchased a 350GB iomega hard drive to try and save my programs from a dying 622. The problem is the 622 only recognizes the drive intermittently after plugging it in to the USB port. I was able to successfully format the drive and download all my recorded shows once but the next time I tried plugging it it there was no external drive detected. I have a second 622 with no issues and it has the same problem in seeing the drive at the port. What's the trick here. Reboots don't seem to help. Now that I've offloaded my programs they're gone if I can't get this drive to work somehow.
