When I first installed One Care onto my Vista OS I had 40GB portable drive as my J: Drive after attempting my first back-up and finding I did not have enough space, I installed a 750 GB external drive as K: I have chenged every setting I can find to back up to the K: Drive and have done back-ups outside of One Care perfectly fine - for some reason ONe Care is still trying to back up to my J: Drive and I cannot figure out why. I keep getting fail warnings - I have even tried to change the K: drive letter to J: but Vista will not let me.
