Friends got a gift to others advertising U disk, above the printed product advertising. Into the computer, the disk management system, appear as two "hard", where a "hard" in video advertising, product introductions, occupying about 6GB, a piece of "hard" in the files has read-only protection , can not be directly deleted. Another piece of "hard" space 9GB, this should be a 16GB U disk. Friends would like to directly integrate the two "hard" space together, use some of the larger space.

Try to use these two tools, although there are clear the Read Only partition function, but this is not effective advertising U disk, and can not remove the read-only attribute, U disk can not be two "hard" partitions merged together.

After testing, the friend of this ad 16GB U disk, using the Alcor (Alcor) Master
