Hi This is driving me nuts. My Time machine keeps failing. I am backing up to an external Toshiba Drive with 1gb. There is plenty of room left. First I tried to delete the entire time machine folder on the drive (that was very difficult by the way). Then it worked a little again. It stopped worked again. Then i followed this guide: http://pondini.org/TM/A4.html That worked for a little while, but now it stopped working again. I am new to mac and really have no idea what this could be. Any ideas?
