I am using Windows 7 64 bit. I started eraser 4 days ago to erase unused disk space. Over the coarse of the first 3 days my computer was completely unusable while eraser was going. For example, if I tried to open a file or something it would take about an hour or so before it even started thinking about opening. But now, for the last day or so, I think eraser is stuck. The progress bar doesn't seem to be moving at all, and my computer is running like normal. I'm afraid to cancel the current task because I'm showing that I only have 5.95 GB of free space left. And from what I understand from reading other posts, if I cancel the task I won't get access back to all of my disk space. What should I do? How long should I let it run if it doesn't seem to be completing anything or making any more progress?
