Small amount of unallocated space left when creating logical partition
As title states. I was just wondering if this is normal / why does it occur?
I have added a second hard drive to my computer (1TB) and I'm trying to format it with a single logical partion. I've told Partiton Wizard to create a single partition but it always leaves 15.75MB unallocated at the begining of the drive. I'm not worried about losing 15MB but I would like to know why it's there? Is it how hard drives/Windows/Partition Wizard work, or something else?
If I try formatting it with a single partition but as "active" instead of logical, it lets me use the whole thing.
Screenshots of Partition Wizard, the 1TB drive is Disk 2:

Try to resize partition to use whole disk
Resize attempt gives same result
Deleting the partition and creating a new one as Primary allows the whole thing to be used
Edit: Just tried again and I'm getting the same effect but with 7.88MB unallocated (half of what it was before). I haven't changed anything, just closed Partition Wizard and opened it again.
Edit 2: I got rid of that unallocated space by using the move/resize option and unchecking "Using enhanced data protecting mode". Still interested in an explanation if anyone knows how it was doing whatever it was.

Windows likes to have a small amount of unallocated buffer space at the end of a drive to use when converting basic and dynamic disks. Without it the conversion may fail.
Likes to have it in the beginning of the drive if you are trying to create an extended partition at the front of the drive.
