I have set the sanpolicy of my win8PE to 3 so that all internal and external disks get offline. It is said that the diskpart couldn't change the settings and make disks online when the sanpolicy was set to 3. But during my experiment I could able to make a pendrive online using diskpart commands(ie. online disk and clear readonly). Some times it worked and other times it won't (showing virtual disk service error). And when I get succeeded in making disk online,I could even create a file in the pendrive from an application runs from win pe. Please clarify this.
If it is possible to make some selected disks online using diskpart what is the correct procedure that always gives positive result ?.
