Hi everyone! I hope the post is in the appropriate section of the forum! You are about to hear the stupidest thing ever done. I recently formatted my laptop and installed 64-Bits version of my Windows 7 Home Premium copy as I am planning to install more RAMs. Before I had 32-Bits version and I had partitioned the HDD into two so that I install Win 7 into C and I keep my personal files such as pictures, movies, work files, etc. in D. Whenever I installed 64-Bits, I had file permission problems in partition D, obviously. However, I solved that problem and I was able to use my old files except a couple of music folders. When I was trying to get permissions for those too, I removed the permissions to the partition D itself. Now, my partition is not accessible. It says "Location is not available. D:\ is not accessible. Assess is denied." Whenever I try to go to right-click->Properties, Security tap is not there. I would really appreciate if some one could help to gain permissions to partition D so that I can access the partition and use my files. All of my important files are in partition D. Thank you very much for the quick reply.

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
