I'm about to format one of my harddrives (C and to back up the data I deleted unnecessary files on drive D: and tried to back up the data there. Now the problem is that to back up the data I need more free space (that's why I deleted the unnecessary files). When I have deleted the files and tried to move data from C: to D: Windows XP said no. That's because the harddrive had not updated the free space stats, i.e. there is more free space that's not visible. My D: drive has 111 Gb of storage and windows says that it's only 2,37 Gb free, although I have deleted files so that the entire space taken by other files is only 96 Gb. The unupdated harddrive stats makes Windows not allow my copy, even if I have enough space. Does anyone know how to update the harddrive stats?
