1. 右擊 D drive
2. click Properties, then choose Security tab
3. add "Administrators" and grant it all permissions
4. click Apply, then OK to exit
5. Try to access D again
如果 Administrators 已經在那裏, do the following:
1. click Advanced
2. choose Administrators from the list
3. check the box labeled "Replace permission entries on all child objects with entries shown here that apply to child objects"
4. click Apply then OK to exit
5. Try to access D again
如果這樣還不 work, do a clean-installation (means to reformatting your partition C and installing your OS upon C again), and then repeat the steps I mentioned above once again after the successful installation, and to see how it would be.
Let me know any questions you may have and good luck!
