I have installed ubuntu 18.04.3 LTS in my system 3 months ago. After 2 months, I don't have the read and write permission on any internal drive except my system drive. I have used chmod -R 777 * in all 4 internal drives. Still I am not able to get the write permission. Every time I use chmod -R 777 *, It sets read only permission to every file.
That's the console output I am getting.
chmod: changing permissions of 'filename.jpg': Read-only file system
chmod: changing permissions of 'filename.mp4': Read-only file system
Content of /etc/fstab file:
# /etc/fstab: static file system information. # # Use 'blkid' 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). # # # / was on /dev/sda8 during installation UUID=659a2d1e-22aa-4ea8-a2fe-95e725d1b4c3 / ext4 errors=remount-ro 0 1 # swap was on /dev/sda9 during installation UUID=229f248a-cec6-40bc-bed9-6a1f1baf8deb none swap sw 0 0

chmod -R 777on an entire drive! That could easily break your system! That said, please edit your question and add i) the contents of the/etc/fstabfile and ii) the output ofmount | grep '^/'.
