Are all "TiVo Premiere" (no suffix) units the same? My two Premieres are described in my TiVo account as 746-0001-xxxx-xxxx. Premiere #1 has died with the repeated GSOD. TiVo support suggested I disconnect everything except the HDMI cable, and that didn't help anything. The whining noise leads me to suspect that the HDD has died. I have a new 2 TB HDD in shipment right now, but it's bare, and I just realized I may not be able to copy anything off the dying/dead HDD. Is my other Premiere the same model? Can I extract the HDD from Premiere #2, copy it to the bare HDD, and insert back into Premiere #1 for happiness and joy? Thanks!
