Hey Dudelive,
Thanks for the tip. I too have PerfectDisk. Just found out where all my extra space is going too... The pesty Norton Protect is holding on to the large files I am deleting. I have disabled Norton Protect on my primary drive, but not on my secondary drive. I got all the space back after I purged the files from the protected recycle bin! WOOT!
Thanks again everyone for helping me with this issue!

Have a beer on me!
