I am facing a wired problem and that is whenever I insert any USB drive or SD card in my computer, all folder and files inside it appear as locked! And therefore I can't crate any new folder and delete any folder from sd card or usb drive! I don't know why it is happening and how to solve this. Anybody please help me.

Type in:

sudo su

enter your password.

Type in:

chown <your_user_name> <disk_name>

type:

exit

EDIT:

If your media is mounted read-only, it is probably needed to check group permissions:

First thing to do is to check the permissions on the hardware device mounting your card. You'll need to find the device name. To do this run the following command:

sudo fdisk -l

Your device will probably be something along the lines of /dev/sdb1, it can be the SD Reader /dev/mmcblk0p1.

Next you need to get the permissions on this device:

sudo ls -l /dev/mmcblk0p1

Replace "/dev/mmcblk0p1" with your device location.

You need to be a member of group disk to be able to write to the SD card. You can check which groups your a member of with

groups username

so then:

sudo usermod -G --append disk username

This adds the group disk to your user's groups, which should allow you to now read & write to the SD card.
