What is the difference between gpt format and mbr format when partitioning hard disk?
"gpt format" has brought many new features, and it can support the large capacity of 18EB at most (1EB= 1024 PB, 1PB= 1024 TB).
"mbr format" only supports 2TB at most, but it has the best compatibility.
MBR partition:
MBR means "master boot record" and has its own launcher, which is the startup code. Once the startup code is destroyed, the system cannot be started, and the system can only be started through repair. The maximum capacity is 2TB, which has a big bottleneck, so GPT will be more and more dominant in the future, and MBR will be gradually replaced by GPT.
GPT partition:
GPT means GUID partition table, which is a new standard gradually replacing MBR. It is supplemented by UEFI, so that UEFI replaces the old BIOS and GPT replaces the old MBR. This standard is not limited by MBR. The capacity of a disk drive can be so large that neither the operating system nor the file system can support it. It also supports almost unlimited number of partitions, limited only by the operating system, and Windows supports at most 128 GPT partitions. With UEFI, all 64-bit win0, win8, win7 and Vista and the corresponding servers can be started from GPT.
