OTA ONLY and Loving It!
That is a good thought - that has been a big issue with lots of drives shucked from WD external enclosures. It is pretty simple to block the pin 3 connection with a tiny strip of tape, so that would be an excellent test for anyone who has a new drive that simply will not boot up at all.It is possible that some of these drives conform to SATA 3.3 specs, if they do supplying power to PIN number 3 will spin down the drive. This is an issue with older computers and could be a problem with tivo.
But this issue cannot apply if the drive is powered from a molex to SATA adapter. In addition, if the drive is in an external enclosure and it does work in that enclosure when connected to a computer, then the pin 3 issue does not apply.
