5. Why is the extended volume gray and unavailable? Small series here science, the expansion of space can only be extended from adjacent partitions, and can not separate a disk for expansion, and the extended partition must and adjacent partition "partition type" must be the same, our C disk is the primary partition, and the adjacent D disk is a logical partition, So now the C disk can not expand the space, we want to expand the space method of C disk a lot of, for example, we can use other software to the D disk also changed to the main partition, today the small series on the use of other software, we look at the small set of methods used!
