Missing Free Space on NTFS Drive

[BikerDude72]

I have a 250Gb SATA drive formated NTFS and using XP. It is my boot drive. I am not using Norton, so there are no protected files in my recycle bin and I've removed all files from the recycle bin. Windows Explorer says that i have 103Gb free and 143Gb used. When I select all files on the drive and click properties it shows only 28Gb files. I've used various 3rd party tools to analyze the drive. The results are below.

It appears i have about 110Gb used but unaccounted for. Any ideas? My system is boots up very slow and has started running chkdsk each boot. Running check disk and defragging has not solved the problem either.

It's a bit of a stupid question probably, but do you have a newer BIOS that supports the larger SATA drive?

Any chance you can post a screen shot from SpaceMonger as it appears to be seeing the missing space in its calcs...

I believe my bios supports larget SATA drives. I have 2 250Gb drives and they both registar as ~250Gb. Here is my bios rev is 1002 for the Asus A8N-SLI Deluxe. How do I post a screen shot?
