Hmmm interesting I have a couple of questions.

1. Do you have administartive priviliges for the account you are doing this from?

2. Have you tried doing a search in safe mode?

When you start you computer before windows starts press the F8 key. It should give you options how to start windows then select safe mode.

midnight_blue I think if the hard drive was being shared it would show in the libray.

one last after thought how many icomplete files are you showing in the icomplete folder in the library?
