I am having a weird hard disk problem. I have a fresh Windows XP VM that I created using the express install feature in 3150. After installing Access 97, Office 2007, and running all of the updates, my hard disk properties report that I am using 7.12GB out of 31.2GB. But when I select all files (after unhiding hidden and protected system files) it only shows 4.05GB of data. What is that extra 3+GB difference between the reported hard disk usage and reported size of my data? The main reason I am worried is that the virtual hard disk file takes up 7.33GB in OSX, and I would like to keep that as small as possible. I have run Parallels Compressor from within the VM - no change. I tried clicking on "Compact" under the advanced settings for the hard disk in the Configuration Editor - no change. Thanks in advance for any help or explanations! --Andrew
