I have just reinstalled Windows XP professional on a machine. The hard drive is a single partitioned 200 GB Maxtor. When I installed the OS I am quite sure I was able to see all the space, about 186.3 GB. The file system I am using is NTFS. If I open the HD properties or I go to Disk Management I can see 186.3 GB (healthy System). Everything looks fine.
Here is the issue: The space available is only 63%, about 119 GB. So far I have installed the OS, Windows updates and Office. When I saw that number I thought, that can be possible. If I take all the files of the HD, included the pagefile.sys file (~ 1GB) the total amount of files in my system is about 7GB. What happened to the rest? The GB used are 67. about 60 more that what they should be. The only difference from the previous installation (that got corrupted after a power outage) is a new driver I downloaded from the web of my ALL-IN-WONDER 9000 Radeon video card.
The defragger also doesn't show the 60 GB. It says the available space is only 63% but only 10% of the picture has files.
I have never seen this before. Sometimes programs allocate space before actually using it to make sure they don't run out of it. I thought it could have something to do with the ATI card that could allocate space for Video capturing in advance. The old driver never did that. What I don't understand is that the file should be visible even if empty., shouldn't it?
I looked into the ATI setting and I can't find anything. Further more when the card starts capturing video, it used the remaining space (not the 60 GB that I can't find anymore).

Any suggestions?

Reason I asked is the limitation of 137 Gig, but as you said above, then it is something else.

Did you go Maxtor website and download diagnostic tool and test the drive? maxBlast is utility. Try that.
