I just replaced my 320 gig drives with 2 Hitachi 2 TB drives.  I am running FW 1.08 and the drives can be formatted to standard, but as soon as I try to setup RAID I have issues.  The unit will freeze when trying to setup a RAID of 500 gig or more.  I am unable to ping the unit or get web access, the lights on the front stop flashing.  I was able to setup a 500 gig RAID successfully, but that is not what I need.   I can put the 320 gig drives back in a re-sync and the unit is works fine.  Any help would be greatly appreciated, I have put over 20 hours into the unit, no server access for at least a week and am getting ready to get rid of it and purchase another manufacture.
Thank you,
