Specifying F: (or F:\) would test the filesystem, not the partition. I'm 
not aware of any way to easily test the area of disk on which the 
partition resides - you'd need to test the disk \\.\PhysicalDriveX and 
seek to the starting sector.  However, Windows prevents writes to areas 
of a disk which contains filesystems, so you would only be able to read 
and not write.
