Sorry if this has been answered before, but I've not found the exact answer. Most of the questions pertaining to this are from people who are wanting to upgrade a drive, or retain their stored programming. I have a HR20-700 that I swapped out the original 320Gb Seagate DB35 drive, for a already set-up 1.5Tb drive (perhaps from WeakKnees). It worked great for several years. In the meantime, I sold the 320G Seagate, which was shortsighted. So i'm familiar with opening the DVR up and replacing drives. Now the 1.5Tb drive has an unrecoverable error, and won't come up, can't get picture, can't run a surface scan, etc. At this point, I'm only using this DVR as a backup, so I don't want to spend $200+ on another 1.5Tb drive that's set to go. My question is this - I don't care about what's on the 1.5Tb drive, it's a write-off. If I buy just a new standard Seagate DB35 drive (320Gb to 750Gb, presumably unformatted), plug it into the DVR and do a format within the DVR, would the drive then be set up to make new recordings? I can pick up one of these drives for $30-40, which I'm willing to do to have a 2nd DVR working again, as a backup, or for a third program at the same time. Thanks for any help.
