Basically if you go to properties on the disk it says I have 2GB free on a 20GB harddrive (old laptop) but if I select all the files and folders in root directory... including hidden files, it says it only adds up to 11GBs. 20GB-11GB does not equal 2GBs. I should have 8-9GBs free. I have emptied the trash, shown all hidden files/directories, and I can still only find 11GBs. I have also run "chkdsk" on the whole drive... I assume it would catch the problem if it were a disk error. If it's of any relevance it's a Lenovo laptop with the security chip in it... but I only have a 200MB security partition... and even that registers as a file I can find in the root directory. What is going on here?
