external drive is mounted as read only now

Asked by SCOTT GEORGE

Hello I recently had my external drive switch to read only on me out of no where. now I can not transfer files to and from, I also can not modify fstab I tried to switch to ro/rw but said I did not have permission everything was fine a few days ago. there is an error it reads # /etc/fstab: static file system information.
#
# Use 'blkid -o value -s UUID' to print the universally unique identifier
# for a device; this may be used with UUID= as a more robust way to name
# devices that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc defaults 0 0
# / was on /dev/sda1 during installation
UUID=240bf3c8-58a6-4383-8e36-628d197b38de / ext4 errors=remount-ro 0 1
# swap was on /dev/sda5 during installation
UUID=5a1c99ef-8551-464f-97c7-ea20da320c62 none swap sw 0 0

Might be your external drive has the filesystem with errors in it so it is mounted in read only mode to preserve your data.
Please perform a filesystem check on that external filesystem, to perform filesystem check the filesystem must be unmounted.

if it is your root partition: UUID=240bf3c8-58a6-4383-8e36-628d197b38de / ext4 errors=remount-ro 0 1
Please boot from Ubuntu live cd and perform the filesystem check from it.
