logical partitions.Security: GPT is more secure because partitioned tables are backed up, and a validation algorithm is added, which, once infected or mistakenly manipulated, can be found in a timely manner, using a secure backup of the partition table to remediate.Partition capacity: GPT can identify hard disks larger than 2T, while MBR recognizes 2.2T capacityWorkaround:1. If it is a new hard disk, use the Diskgenuis conversion partition table type as GUID format (P) to select OK until the co
