I have a 500gb FreeAgent p/n #9f2al-570, and it works great with fta receivers, had it on a cs-8000, but now it is on a SV-8000, don't own the CS any more.
now it was a little tricky to get set up at 1st, I have used swiss knife in the past, but this did not work for me here with this drive. what did work was going to the Sea Gate web site and down loading their program for this HD, then re-formated it, turn sleep mode off, plug into receiver then power up HD and works like a champ. most of the time if I reboot receive also repower HD for it to be found.
