Enter "sudo /sbin/fdisk -l" to get a list of the drives and partitions on your system. "D drive" is an MSDOS term. Linux partitions will be called something like /dev/sda1 or /dev/hda1 depending on your kernel version. Do you have only one drive in your laptop, with 2 or more partitions? If so it will probably be /dev/hda2 or /dev/sda2. The output of the fdisk -l command will indicate the filetype.
You can also use "udevinfo -q env -n /dev/hda2" to find what filesystem is on the second partition.
Is this the second partition on your internal drive or an external drive?
Is it formatted using either fat32 or NTFS? If so then you need to change some mount options. Use "uid=<your_user_name>,gui=<your_group>". This will determine the ownership of the files and directories. Use "fmask=0117,dmask=0007" to allow read and write access for the owner and group.
E.G.
sudo mount -t vfat /dev/sda2 /mnt/movies -o rw,uid=teja,gid=teja,fmask=0117,dmask=007
If the filesystem is a native filesystem, then after mounting, use the "chown" command to change the ownership, and the "chmod" to change the permissions. This needs to be done while the filesystem is mounted.
E.G.: sudo chown teja.teja /mnt/movies
sudo chmod ug=rwx /mnt/movies
