Here is a list of reasons and one of them may be the cause that makes your disk partition displaying Healthy GPT Protective Partition :. People mainly use GPT protective partitions on Servers for preventing others from manipulating confidential information or providing redundancy for critical data. Some personal users also use it to maximize the partition size or to remove restrictions placed on the partition size. In a word, no matter how you get a GPT protective partition, even though Windows recognizes it as a healthy "GPT Protective Partition", you will not be able to read or boot from it.
As a result, data becomes inaccessible. So how do you access the GPT protective partition data and get rid of this error? Check and follow the provided solutions to make your GPT protective partition work again.
Applies to: Access and restore precious data from the GPT protective partition in advance. When the GPT disk partitions become protective, you can't access, delete, or even format the GPT protective partition. Before you get started to remove the GPT protective partition, we suggest you find a reliable data recovery solution to restore the saved data from the problematic partition.
As long as your disk can be detected by Windows Disk Management, it will recognize your GPT protective partition and effectively scan and find all your data.
Step 1. Select the hard drive which becomes inaccessible on your PC. Click "Scan" to let this program scan and find your hard drive data. Step 2. After the scan, you can preview and check found files on the scanning result window. You can also click "Filter" to quickly find a specific type of file. Then, you can preview the file by double-clicking it.
Choose a secure location a healthy physical drive on your PC or another external storage device and click "OK" to start recovering all lost data from your inaccessible hard drive. Remember to save the restored data to another secure location on your computer or an external hard drive.

The GPT header defines the range of logical block addresses that are usable by partition entries. The byte partition type GUID, which is similar to a System ID in the partition table of an MBR disk, identifies the type of data that the partition contains and identifies how the partition is used, for example, whether it is a basic disk or a dynamic disk.
Note that each GUID partition entry has a backup copy. For more information about basic disks, see Basic and Dynamic Disks. Dynamic disks were first introduced with Windows and provide features that basic disks don't, such as the ability to create volumes that span multiple disks spanned and striped volumes and the ability to create fault-tolerant volumes mirrored and RAID-5 volumes.
For more information about dynamic disks, see Basic and Dynamic Disks. GPT disks are self-identifying. All the information needed to interpret the partitioning scheme of a GPT disk is completely contained in structures in specified locations on the physical media.
Logical blocks are commonly bytes in size. The maximum partition and disk size depends on the operating system version.
Windows XP and the original release of Windows Server have a limit of 2TB per physical disk, including all partitions. Windows file systems currently are limited to terabytes each. The specification allows an almost unlimited number of partitions. However, the Windows implementation restricts this to partitions. The number of partitions is limited by the amount of space reserved for partition entries in the GPT.
These tools will view a GPT disk as having a single encompassing possibly unrecognized partition by interpreting the Protected MBR, rather than mistaking the disk for one that is unpartitioned. For more information, see the following sections:. The bit version will see only the Protective MBR. The EE partition will not be mounted or otherwise exposed to application software.
Booting is only supported for bit editions on Itanium-based systems. Yes, all versions can use GPT partitioned disks for data. Booting is only supported for bit editions on UEFI-based systems. You can move, or migrate, data-only GPT disks to other systems that are running Windows XP bit edition only or later versions of the operating system or bit editions.
You can migrate data-only GPT disks after the system has been shutdown or after the safe removal of the disk. However, you must be aware of the following restrictions:. The entire media is treated as a single partition. The media manufacturer performs any MBR partitioning of removable media.
If the media has an MBR, only one partition is supported. There is little user-discernible difference between MBR-partitioned media and superfloppies.
GPT disks can be converted to MBR disks only if all existing partitioning is first deleted, with associated loss of data. There is no inherent mapping between drive letter and partition that can be used to determine one from the other. A basic data partition must be identified by its partition GUID. You shouldn't directly change any partition header entry.
Don't use disk tools or utilities to make alterations or changes. Detachable disks are typically expected to migrate between computers or simply to be unavailable to the operating system at times. Examples of detachable disks are USB disks, which can be easily disconnected by the end-user. Later versions of Windows support GPT partitions on detachable disks. ESP partitions can be replicated for high-availability configurations. This is a data destructive process.
This procedure not only removes the drive's partition, but also removes the Drive Signature. You must open Disk Management and document the Disk Number of the drive containing the GPT Protective partition, as you will need this information later in the procedure.
