How is data stored on disk? - EFI GUID

问题 I posted this question earlier on SuperUser but I feel it is more suited for programmers. If I understand correctly, according to GPT, the first 16 bytes of LBA 2 is the partition type GUID for the first partition on disk. In Windows Disk Management the first partition is designated as an EFI System Partition. However upon further investigation an EFI System Partition's GUID is: C12A7328-F81F-11D2-BA4B-00A0C93EC93B And yet the first 16 bytes tell me otherwise: 28732AC1-1FF8-D211-BA4B

问题 Is there a way to tell if a disk has a GPT or an MBR partition with powershell? 回答1: Using WMI gwmi -query "Select * from Win32_DiskPartition WHERE Index = 0" | Select-Object DiskIndex, @{Name="GPT";Expression={$_.Type.StartsWith("GPT")}} Using Diskpart $a = "list disk" | diskpart $m = [String]::Join("`n", $a) | Select-String -Pattern "Disk (\d+).{43}(.)" -AllMatches $m.Matches | Select-Object @{Name="DiskIndex";Expression={$_.Groups[1].Value}}, @{Name="GPT";Expression={$_.Groups[2].Value -eq
