Success! My previous post outlined an epic fail between a WE30EURS/ThermalTake BlacX Dock and my HR44-700. I returned them and this is what worked:
The following worked perfectly, first try, no special treatment, just quickly assemble the enclosure, drop the drive in, push forward to mate with connectors, flip holding clip. Ready to go.
Western Digital WD20EURX (2 TB SATA III, Amazon)
ThermalTake Max 5 Active Cooking Enclosure (Amazon: double quiet fans, lighted if desired)
Standard connection/startup procedure:
1. Shut down HR44-700 (I used Menu Restart)
2. When front panel lights go out, pull power plug on HR44
3. Connect eSATA cable between HR44 and the Enclosure
4. Power Up Enclosure and wait 1 minute.
5. Put HR44 Power Plug back in (it will auto power up)
Watch drive light on the enclosure, it will flash intermittently and continue to do so. As the HR44 comes alive, the screen will tell you it is formatting the external drive.
I have no idea why the other setup would not work out of the box on the HR44. I dropped down from 3 TB to 2 TB when I ordered this newt setup, only because I thought 3 was too big to have so much stuff on when it failed (and it will, eventually). I am using a BlacX Dock on my HR24-200 with a 2 TB drive successfully.
Since I changed type of interface (Dock > Full Enclosure), and Size (3 TB > 2 TB), and of course it was physically a different drive, I can't tell anyone why the first setup would not work. It could have been a bad dock, a bad drive, requirement that the drive be initialized (per P. Smith), etc.
Of course, I have to input all my series links and I lost the Sports Search (which should return in a few days), and have to wait a few days for the series links to populate, but at least now I have enough space to due the 5 tuners in the HR44 some justice.
