DriveSetup allows corruption of mounted filesystems

[kallisti5]

To reproduce:

• Initialize Intel Partition Map on disk
• Create a new partition
• Format partition as BFS
• Mount partition
• Format disk as BFS

Check for mounted file systems on disk doesn't occur and you get an invalid mount on the system.

This sounds more like something the kernel side of the disk systems should be forbidding, since that's where all the actual initialization work happens.
