, and it has a disk partition and backup partition table, providing troubleshooting functionality. GPT disks use EFI as a bridge between computer hardware and the operating system.A GPT disk can create 128 primary partitions. Because there can be up to 128 primary partitions, GPT disks do not require an extended partition. Partitions larger than 2TB, you must use GPT disks.The user may convert these two types of disks to each other.The following is th

I. OverviewIn previous storage systems, RAID technology was generally used to protect data, and once a hard drive in the array was damaged, the lost data could be recovered by a mirror formed by the raid technology. But with the advent of massive data problems, RAID is becoming more and more difficult to play its part. If you use a 2TB hard disk as a storage medium, a hard drive fails, it takes about 4 hours to restore it using an image, and this is t

There must be at least one primary partition (P), the number of primary partitions + the number of extended partitions After you create the primary partition, you can create an extended partition (E), which can have 1 or no (extended partitions).Primary partitions (Primary partion) can be used immediately but cannot be partitioned. The extended partition (Extension partion) must be partitioned before it can be used, the extended partition cannot be used directly, and a logical partition must be
