Chmod: Everything on Sd Card Stuck on 755, Owner Is Root

I am trying to access my SD card as a general user after it somehow changed to just Root access. I have tried several solutions, and none of them worked. Here is an attempt to chown eveything to ubuntu (Using a live USB here):
$ sudo chown ubuntu -R /media/ubuntu
chown: changing ownership of ‘/media/ubuntu/JUSTADOO444/(Every single file/folder)’: Operation not permitted
chown: changing ownership of ‘/media/ubuntu/JUSTADOO444’: Operation not permitted
And after an attempt to chmod everything to 777:
Command:
$ sudo chmod 777 /media/ubuntu/ -v -R
mode of ‘/media/ubuntu/JUSTADOO444/(Everything)’ changed from 0755 (rwxr-xr-x) to 0777 (rwxrwxrwx)
And after a quick ls -l:
drwxr-xr-x 5 root root 4096 Sep 8 18:54 Sample Folder (Name Changed)
-rwxr-xr-x 1 root root 4402055 Sep 16 11:53 Sample Presentation.odp
This is getting on my nerves. I have to use sudo before every single thing I try to do to my SD card. (It has a LOT of data on it, too, and I am unlucky enough to not have a space to backup. If only my 16gb flash drive wasn't being used for Ubuntu booting only...)

How is your SD card mounted?
mount | grep /media/ubuntu
Do you see ro or rw? You can remount it read/write by:
sudo mount -o remount,rw /media/ubuntu
If you read man 8 mount you can add an entry into /etc/fstab (man 5 fstab) that will allow a specified user, or all users to mount (and own) the SD card.
Have you tried adding uid=your_username to the mount options. It worked for me and changes the Owner to me everytime I plug it in
For me this was because I had an SD card formatted as a FAT32 filesystem. Fat32 doesn't support file permissions.
