HDD with Power Disable Feature Usable in Roamio OTA?

    Wanting to upgrade the storage in my TiVo Roamio OTA (All-In), I purchased a Western Digital EasyStore 8TB External Drive at Best Buy hoping to find a WD80EFAX Red drive inside. Unfortunately, once shucked, the drive turned out to be a white labeled WD80EMAZ drive with the Power Disable Feature (SATA Rev. 3.3 or 3.2+). My understanding is that if a unit's power supply provides +3.3V on pin 3 of the SATA power connector the drive interprets that as "Power Disable" and the drive will not spin up. My question then is: Does my Tivo Roamio OTA's power supply provide +3.3V to pin 3, thus causing this HDD to not spin up? If so, how exactly can I effectively block that +3.3V signal from the TiVo and thereby use this drive to upgrade its storage?

    AFAIK, Roamios don't even have a 3.3V bus (that was the original Series 3).

    Have you placed WD80EMAZ drive into your Roamio yet? Does it power up?

    Yes, I have successfully upgraded my Roamio OTA to the 8TB drive. No problem between the Roamio and the 8TB WD80EMAZ. Only problem I had was formatting and checking the drive in my older PC whose power to the motherboard-supplied eSATA power connector did cause problems for me. So instead of using that, I popped open the PC case and attached the drive to one of the on-board SATA ports and used a simple, generic, Molex to SATA power cable adapter, and that worked like a charm.

    Excellent! I will go ahead and shuck the EasyStore drive to get the WD80EMAZ out.
