Hi, No Security tab can be caused due to the file system of Drive D is not NTFS. Please right click on Drive D and click Properties to check the file system. If the file system is FAT32, you may perform the following steps to convert it to NTFS. After that, you can modify the permission settings under Security tab. NOTE: Although the possibility of corruption or data loss during the conversion is minimal, it is recommended that you perform a backup of the data on the volume that needs to be converted before starting the conversion. To convert an existing FAT or FAT32 volume to NTFS, please follow these steps: 1. Click "Start", click "All programs", and click "Accessories". 2. Right-click "Command Prompt", and click "Run as administrator". 3. In "Administrator: Command Prompt" window, type the following command and press Enter. CONVERT %drive letter%: /FS:NTFS %drive letter% is the driver that you want to convert. For example, type the following command to convert the E Drive to NTFS: CONVERT E: /FS:NTFS 3. When the following message is displayed in the command prompt window, type the volume label of the drive that you are converting, and then press ENTER: The type of the file system is FAT. Enter the current volume label for drive %drive letter%: Type any character string for the Volume Label. If you just press Enter, it will assign "Local Disk" as the default Volume Label. 4. When the conversion to NTFS is complete, the following line is displayed in the command prompt window: "Conversion complete" 5. Quit the command prompt. Does it work? Regards,Arthur Li - MSFT
