I used True Image 10 (build before this last Vista build) to clone a 40 GB primary hard drive to a 160 GB hard drive on an XP SP2 system. Everything seemed fine for the last week. Now it tells me that System Restore will not work since there is "not enough space on my disk." It believes that 10% of my 160 GB disk is 500MB! It still has 2/3 available. So I then tried to "check for errors" in Windows XP and it "could not finish". What can I do to fix this? And for future reference, how dos something like this occur. When I cloned it, I just placed the new drivein the second drive slot, followed the cloning prompts, and then replaced the old drive with the new drive with the right jumper setting.
