Well, I could not just sit and wait, wrote the good backup onto the Skyhawk and away we went, all good, mounting holes
all match up, easy as peeing shells. I will probably retire the WD320 Green and just leave the Skyhawk in there for long term
and still have a spare HDD. So, for the price (unbelievable) I vote the Skyhawk.
Also figured out a cure for the constant rebooting at 2am of both Tivos, just do the update at 7am so the sorting is not upset
by the 2am reboot, all good.
