Thanks. Did you notice that this is OPTIONAL?
As is the cable provider does not have to enable this?
"Check with your cable service provider for a list of
approved hard drive models for use with the 8300HD"
We see this a lot with other things. Folk want to add those relatively new to such boxes larger than 500GB drives so if I was to try this I'd stick to 500GB if no one will answer your questions.
All I read is that it's OPTIONAL and that's the code word that not all of these boxes will do this or that the cable provider can switch it off.
WHY IS THAT? Simple. They love to nickel and dime us. If they can get 5 bucks a month for "Premium Extended Recording" then they will.
The eSATA cable here was 3 bucks so not a terrible amount to gamble. Be sure your drive is in some powered case since eSATA does not provide drive power.
