Error:
The operation failed to complete because the Disk Management console view is not up-to-date. Refresh the view by using the refresh task. If the problem persists close the Disk Management console, then restart Disk Management or restart the computer.

Story:
After install Norton Partition Magic 8 on my Windows 7, my last partition flies to die. I could not see that or change drive letter in Disk Management.

Solution:
- Install Acronis Disk Director Suite.
- Find Your partition and Right Click on it and Select Advanced > Convert to same last time (for example i select NTFS-Logical) and after commit the changes you can set a drive letter for your partition and make a celebrity for this :-D [specially thanks to Ahmad Ibrahim]
