I have three NTFS partitions on a disk. Windows 10 is installed on one. I would like to prevent Windows from discovering one of those partitions (the third one), or, at least prevent Windows from mounting it automatically.

Is this possible?


Go into Disk management and remove the assigned drive letter.

  • start compmgmt.msc as administrator
  • Storage -. Disk Management
  • Right click on the drive/volume and select 'Change Drive Letters and Paths...'
  • Select and remove the currently assigned letter.

    As a note you can also run "diskmgmt.msc" directly to get just the disk management snap-in. – kyle_engineer May 16 '17 at 17:22
