My system is having multiple internal hard disks and due to some memory concerns I have to work on the second drive(hdd2). Then on visiting "/mnt/hdd2", I found entire drive is protected by root. To change the privileges, I tried the normal way:
sudo chmod 755 /mnt/hdd2Result : NO CHANGE.
sudo chmod a+x /mnt/hdd2Result : NO CHANGE.
No I googled I find:
sudo chmod -R 755 /mnt/hdd2Result : To my surprise NO CHANGE
Here is the solution:
sudo chown -R chaithanya:chaithanya /mnt/hdd2Result : SUCCESS ('chaithanya' is the username).
