    Unable to change permission for external drive on ubuntu

    How can I change the file permission of the external drive???? Well I used to transfer data among various computers. In today morning I found as read-only file system rather than of writeable stick. Is there any work around to make the stick read and write???? Any help on the above mentioned issue will be highly appreciated. Thanks a lot in advance.

    Well after going through the issue i am suspecting that the USB stick is mounted as read only. You should use the following steps.
    You should run below mentioned command to find out which device it is,
    mount

    after that you should unmount USB device by using following command.
    Code:
    sudo umount /dev/sdd1
    after that check and repairs on USB disk.
    Code:
    sudo fsck -r /dev/sdd1
    once done you should remove the USB drive and put in back on the pc, see whether mount is read or write.

    Make sure that USB driver or external hard drive should not use FAT32. In fact FAT32 is not having all the permissions settings for the Linux based fie system.

    In this particular issue I recommend that you should edit the fstab. If you are looking to mount the driver of yours with the write permission then you will need to unmount the drive. By simply right click on the driver and click on Unmount. Or you can do ‘umount '/media/Expansion Drive' once you have done with the same you have to mount the drive by using following command.
    Code:
    mount -o rw /dev/sd.. /media/External_drive
    also you should create a directory by using following command.
    Code:
    sudo mkdir -p /media/External_drive

    You can also use following solution to fix the matter of yours.
    Code:
    mount -o uid=username,gid=groupname /dev/sdc /path/to/mount
    after that you should run below mentioned command.
    Code:
    chown -R user *
    chown -R user .
