Pros: WORKS with Dtv HR20/700 Should work with all Esata compatible Dtv recorders. Connected supplied Esata cable, turned on hard drive plugged in HR20 and it booted and I now have 1gb of recording space. Could not have been easier. Nice looking box, runs cool and quiet.

Cons: None at this time.

Overall Review: I am writing this early review to let people know that: THIS DRIVE WORKS WITH DIRECT TV HD DVR RECORDERS. All of the other reviewers used the drive with computers and I know there are a lot of people looking for compatible drives to expand their Dtv recorders storage space. I will update if problems arise as drive has only been installed for 2 days.
