She has been part of the EaseUS team for over 5 years. Her special focuses are data recovery, disk partitioning, data space optimization, data backup and Mac OS. By the way, she's an aviation fan! It makes it way easier to play out what will happen after you've made all the changes. I also think the overall look and feel of EaseUS Partition Master Free makes whatever you're doing with your computer's partitions easy.
Partition Master Free can Resize, Move, Merge, Migrate, and Copy disks or partitions; convert to local, change label, defragment, check and explore partition; and much more. A premium upgrade adds free tech support and the ability to resize dynamic volumes. It won't hot image your drives or align them, but since it's coupled with a partition manager, it allows you do perform many tasks at once, instead of just cloning drives.
You can move partitions around, resize them, defragment, and more, along with the other tools you'd expect from a cloning tool. Let it manage your storage drive: resize, format, delete, clone, convert, etc.
Screen Recorder. Transfer Products. File Management. More Products. Of course, all data will be completely erased. Therefore, remove and access the GPT protective partition without losing data, remember to follow steps in Part 1 and restore your precious data in advance.

This post from MiniTool will introduce several useful ways to help you with that; please read carefully. Many people doubt that whether they can read Mac drive on Windows. Some took action: they removed the drive from Mac and connected it to a Windows PC properly. But after connecting the Mac-formatted drive to Windows, a prompt window will pop up automatically on the screen, saying that they need to format the disk before use.
You should click Cancel instead of Format disk when seeing this prompt. That is simply because the formatting action will damage your data saved on that drive. Is there any other way to read a Mac-formatted drive on Windows? Sure, it is; some effective ways used by other users will be shown to you later on this page.
Luckily, the answer is yes. The formatting action is performed to prepare a data storage device including hard disk drive , solid-state drive, USB flash drive, and SD card for initial use. Other value-add files or diagnostics used while the operating system is running should not be placed in the ESP. It is important to note that the space in the ESP is a limited system resource; its primary purpose is to provide storage for the files that are needed to boot the operating system.
The preferred option is for system manufacturers to place value-add contents in an OEM-specific partition. Users are warned that deleting the partition can cause the system to fail to operate. Although not architectural, this placement has the same benefits as placing the ESP first. For example, it is also impossible to span volumes when an OEM-specific partition is logically between the two data partitions that you are attempting to span. Placement in the ESP is an option for applications or files that execute in the pre-operating system boot environment.
However, the ESP is architecturally shared space and represents a limited resource. Consuming space in the ESP should be considered carefully. Files that are not relevant to the pre-operating system boot environment should not be placed in the ESP.
The Microsoft Reserved Partition MSR reserves space on each disk drive for subsequent use by operating system software. GPT disks do not allow hidden sectors. Software components that formerly used hidden sectors now allocate portions of the MSR for component-specific partitions.
For example, converting a basic disk to a dynamic disk causes the MSR on that disk to be reduced in size and a newly created partition holds the dynamic disk database. It is particularly important that the MSR be created before other primary data partitions. The MSR must be created when disk-partitioning information is first written to the drive. If the manufacturer partitions the disk, the manufacturer must create the MSR at the same time. Only one ESP should exist on a system even if multiple operating systems are installed on that system.
In a mirrored boot configuration there may actually be two drives with an ESP but they are considered to be a redundant copy of the same ESP. Each data drive must contain at least an MSR and one basic data partition. All basic data partitions on the drive should be contiguous.
As noted above, placing an OEM-specific or other unrecognized partition between data partitions imposes limitations on later volume spanning.
Each basic partition can be mounted using a drive letter or mount point, other volume device object, or both. Each basic data partition is represented in Windows as a volume device object, and optionally as a mount point or a drive letter. The ESP partition isn't hidden, but also doesn't have an assigned drive letter. It will not appear in Explorer unless a drive letter gets assigned to it, but some tools will be able to list it.
Users will not see these partitions exposed in Windows Explorer, nor is any recognized file system exposed to legacy programs such as Context Indexing. The OEM-specific and other unrecognized partitions will be visible only in the Disk Management MMC snap-in since they will not have a recognizable file system. Windows exposes only basic data partitions. Other partitions with FAT file systems may be mounted, but not exposed only programmatically.
Only basic data partitions are assigned drive letters or mount points. This allows programs running under Windows to update the contents of the ESP.
Access to the ESP requires admin privilege. Any OEM-specific partitions or partitions associated with other operating systems are not recognized by Windows. Unrecognized partitions with recognizable file systems are treated like the ESP.
They will be mounted, but not exposed. Unlike MBR disks, there is no practical difference between OEM-specific partitions and other operating system partitions; all are "unrecognized. The user can use disk management tools such as the Disk Management utility or the diskpart. Replication must be done manually and the contents must be synchronized manually.
Extensible Firmware Interface System Partitions cannot be mirrored. Microsoft places the loader, and other files that are necessary to boot the operating system in the Extensible Firmware Interface System Partition.
While there is no architectural requirement, there are numerous reasons why it is beneficial to place the Extensible Firmware Interface System Partition first. The primary reason for this is that it is impossible to span volumes when the Extensible Firmware Interface System Partition is logically between the two data partitions you are attempting to span. What should a computer or device manufacturer place in the Extensible Firmware Interface System Partition?
The Extensible Firmware Interface System Partition should only include files that are required for booting an operating system, platform tools that run before operating system boot, or files that must be accessed before operating system boot, for example in performing pre-boot system maintenance. Other value-added files or diagnostics that are used while the operating system is running should not be placed in the Extensible Firmware Interface System Partition.

The Microsoft Reserved Partition reserves space on each disk drive for subsequent use by operating system software.
Software components that formerly used hidden sectors now allocate portions of the Microsoft Reserved Partition for component-specific partitions. For example, converting a basic disk to a dynamic disk causes the Microsoft Reserved Partition on that disk to be reduced in size and a newly created partition holds the dynamic disk database. It is particularly important that the Microsoft Reserved Partition be created before other primary data partitions.
The Microsoft Reserved Partition must be created when disk-partitioning information is first written to the drive. If the manufacturer partitions the disk, the manufacturer must create the Microsoft Reserved Partition at the same time. After the disk is partitioned, there will be no free space left to create a Microsoft Reserved Partition. When initially created, the size of the Microsoft Reserved Partition depends on the size of the disk drive:.
Each bootable drive must contain an Extensible Firmware Interface System Partition, a Microsoft Reserved Partition, and at least one basic data partition that contains the operating system. Each data drive must contain at least a Microsoft Reserved Partition and one basic data partition. All basic data partitions on the drive should be contiguous.
As previously noted, placing an OEM-specific or other unrecognized partition between data partitions imposes limitations on later volume spanning. There is a direct one-to-one correlation between a basic data partition and a drive letter or mount point, other volume device object, or both. Each basic data partition is represented in Windows as a volume device object, and optionally as a mount point or a drive letter. The user won't see these partitions exposed in Windows Explorer, nor is any recognized file system exposed to legacy programs such as Context Indexing.
Windows XP exposes only basic data partitions. Other partitions with FAT file systems may be mounted, but not exposed only programmatically. Only basic data partitions are assigned drive letters or mount points. This allows programs running under Windows to update the contents of the Extensible Firmware Interface System Partition.
