Using a Seagate DB35 Series 7200 (ST3300822ACE) the upgrade apperaed to go smoothly, but when going through the setup it just goes into a loop;  from the welcome to ReplayTV through to the 'select guide or menu to continue', then it turns blue and starts over again.  The blue power light NEVER goes off.  Any suggestions what it might be?  Jumpers?  I have it on Master.  ??? Anything?  Thanks in advance!
