This means that you can grant or deny various permissions to individual files to users or groups of users. Data compression: On an NTFS-formatted volume or partition, you can enable data compression so that more files can be stored in the same capacity drive. Disk quotas: To prevent individual users from taking up too much space on a shared volume, you can set disk quotas in NTFS that prevent a user from using more than a specified amount of disk space.
Like compression, encryption can be set on a folder-by-folder or even file-by-file basis. Windows provides a command-line utility called Convert for this purpose.

Also try the troubleshooting steps described in A disk's status is Not Initialized or the disk is missing entirely. Cause: The Foreign status occurs when you move a dynamic disk to the local computer from another computer PC.
A warning icon appears on disks that display the Foreign status. In some cases, a disk that was previously connected to the system can display the Foreign status.
