This protective MBR Disk Utility does not guarantee the old disk to GPT disk space as there is no deal with the MBR partitions and overwrite information already exists GPT. If you are using honest MBR disk tools GPT disk management, you will only see a partition occupies the entire disk. This MBR would think there is a GPT drive occupies the entire disk partitions. Use GPT drives will contain a “ protective MBR”. The MBR is powerless to these questions – only after the problem occurs, you will find that the computer does not start, or disk partitions are missing it. GPT also save the information for these cyclic redundancy check ( CRC) to ensure that it is complete and correct – if the data is destroyed, GPT will find the damage and recover from elsewhere on the disk. Relative, GPT stored on multiple copies of the entire disk information in this section, so it is more robust and can recover corrupted information in this section. If this part of the data is overwritten or destroyed, things trouble. On MBR disks, partitions and boot information is stored together. It also supports a virtually unlimited number of partitions, only restriction is that the operating system supports up to 128 – Windows GPT partition, but you do not need to create an extended partition. Disk drive capacity can be much larger, large operating system and file system support no law. This standard does not that limit the MBR. The reason is called “ GUID Partition Table” because each partition your drive has a globally unique identifier ( globally unique identifier, GUID) – This is a randomly generated string can guarantee for the Earth Each GPT partition is assigned a unique identifier entirely. It complementary – UEFI UEFI to replace the old BIOS, while GPT then replace the old MBR. This is a new standard is gradually replacing the MBR. ( GUID meaning globally unique identifier). GPT is intended for GUID Partition Table. MBR has become the industry standard disk partition and boot.
MBR also only supports up to four primary partitions – if you want more partitions, you need to create so-called “ extended partition” and create logical partitions in it.
MBR maximum support 2TB disk, it can not handle more than 2TB capacity disk.

If you install Linux, you will usually located in the MBR is GRUB loader. If you install Windows, Windows boot loader initial information is placed in this region – if the MBR of information is covered by that Windows can not start, you’ll need to use the Windows MBR repair function to make it back to normal. The so-called boot loader is a small piece of code, on the other partition for greater load on the load drive.
This sector contains the boot loader and drives installed operating system logical partition information. The reason is called “ Master Boot Record”, because it is present in a special boot sector at the beginning of the drive.

MBR means “ Master Boot Record”, the first IBM PC DOS 2.0 proposed in 1983. When you create a partition on the disk, you must make a choice between MBR and GPT. The partition information contains information partition from where to start, so the operating system to know which sector belongs to which partition, and which partition is bootable. MBR ( Master Boot Record) and GPT ( GUID Partition Table) are two different ways to store on disk partition information.

The new standard is not Windows-specific GPT – Mac OS X, Linux, and other operating systems also use GPT.īefore using the new disk, you must be partitioned. GPT has brought a lot of new features, but still has the best compatibility MBR. GPT is a new standard, and gradually replace the MBR.

When setting up a new disk in Windows 8 neu 8.1, the system will ask you want to use the MBR or GPT partition.
