How to delete GPT Protective Partition

November 14, 2009 - PC Dianogstic

In Windows XP Professional, if you cannot access or modify GPT disk, you can convert a GPT disk to MBR by using the clean command in DiskPart, which will remove all data and partition structures from the disk.

  1. You might see S2VR HD 5 Drives in GPT status.
  2. Go to DOS command line (click on “Start Menu”, then “Run”, type in “cmd” in textbox, and hit “OK”)
    • Type in “DiskPart” in command line.
    • Type in “list disk” in command line to show all disks in this machine.
    • Use “select” to set the focus to the specified partition, for example “select disk 1″.
    • Use “clean” command to remove GPT disk from the current in-focus disk by zeroing sectors.
  3. Go back to Disk Management, you can see all S2VR HD disks are “unallocated” now. Right click on disk info, choose “Initialize Disk”.
  4. Choose all drives in S2VR HD and initialize them.

Warning: This command will erase all data on the disk, so please backup your data first.
