I have 2 Samsung Pro NVMe drives in my PC. I have recently noticed in Disk Management that both drives have a 2MB unallocated partition. My one drive is empty, so I deleted the partition and recreated it, but the 2MB unallocated space remains. Why is this happening? When I first installed this partition did not show. I am running Windows 11 25H2
Partition alignment padding: Modern OSes align partitions to 1 MB boundaries for performance. When the math doesnโt land perfectly at the end of the drive, you can end up with 1โ2 MB left over.
Sounds like you've got a mild case of OCD, and I get it, I'm like that too, but for this, I'd just leave it alone. 2MB is negligible. If it really bothers you still, you could try a third party disk utility like Macrium Reflect to create a tiny partition from it, and then merge it with the rest.
