23 I noticed while working on two new laptops with gparted that resizing Windows
24 7 and creating new partitions showed up small blank partitions (marked as
25 hidden) in between the resized, and/or the new partitions. If I recall
26 correctly these were only a few KB each so rather small as such. I am not
27 sure why gparted created these - could it be related to the drive
28 automatically aligning partitions to this 4K sector size that is discussed
29 here?
