And can you clarify what you mean with "the system says". That's the properties of the c:-drive? No other partitions on the hard drive (use Disc Management to check).
There might be some very hidden recovery data put on the Thinkpad by Lenovo. But it's rather absurd that it should be 56 Gb on a 90 Gb harddrive, especially if you say it wasn't like that when the machine was really new.
One of those hidden folders is Windows XP's own System Volume Information. That's where System Restore stores its data (and it's freed when you delete all system restore points). There are ways to have a look inside it: http://support.microsoft.com/kb/309531
Hope this helps, and let us know.
I have a new Thinkpad with windows XP and a 90 GB harddrive. When I use windows explorer and do a select all and properties it shows only 32 GB of data ( and I include the hidden files and subfolders) but the system says I have over 88GB used. I tried chkdsk and it shows no errors and 88GB of data. I tried Sequoia but it only show the 32 GB of items, I also tried CCleaner and it will only clean up 200 MB of Temp Data.
So my question is where can I get software to see what is taking up this space? Does anyone have a recommendation on how to clear this up or is it a phantom in windows XP making this happen?
I looked through all the threads but I can't find what is taking up the space.
