Hard drive memory

[lag]

Properties show free space 20% on 180 GB drive.   When I check the program files and my documents and C drive, the total is only half of what is shown as being used.   What is going on that the pie chart shows most of the drive being used and not free?

check your rescue and recovery backup files, it is probably used by the backups of your systems. start -> program -> thinkvantage -> rescue and recovery. Delete those that you don't need.

The restore files only have about 750 MB in it.   Still searching for 80 GB

Hi lag,

Maybe it's the hibernation and restore point files that Vista has been storing. Following post suggests how to delete it:- http://forum.thinkpads.com/viewtopic.php?t=48794
