Microsoft Reserved Partition
From Wikipedia, the free encyclopedia
The Microsoft Reserved Partition is a partition on a data storage device that is used to reserve space ahead of time for other use[1]. It does not contain any meaningful data itself. The Globally Unique Identifier for the Microsoft Reserved Partition in the GUID Partition Table scheme is E3C9E316-0B5C-4DB8-817D-F92DF00215AE.
Microsoft recommends that the Microsoft Reserved Partition be created when a disc is partitioned, and that it be located after the EFI System Partition and any OEM service partitions. Initially, it is 32MiB (on discs smaller than 16GiB) or 128MiB (on other discs) in size, although it shrinks as the space allocated to it is reallocated to other partitions such as the Logical Disk Manager configuration data partition.
