This question already has an answer here:

I am attempting to rescue files from a broken system via the root terminal of the recovery console.

I have a seagate 2TB external hard drive. Output of sudo fdisk -l:

/dev/sdb1 is the device boot
HPFS/NTFS/exFAT is the system

Everytime I try to copy files to the hard drive via:

sudo cp [file] /media/Expansion\ Drive

I get:

cp: cannot create regular file `/media/Expansion Drive/[file]' : Read only file system

I have tried:

sudo chmod -R 775 /media/Expansion\ Drive
sudo chmod -R 777 /media/Expansion\ Drive


sudo chmod a+rwx -R /media/Expansion\ Drive

and for each command, the output is:

chmod:  changing permissions of `/media/Expasion Drive': Read-only file system

So I'm at a loss. I've tried searching for more help, but the majority of solutions that I have found involve using nautilus of some other GUI and I am unable to access those resources because I can only access from the recovery console root shell

Please help! The crash seemed spontaneous and I was unable to back up my current project... Any help would be greatly appreciated.

This question was marked as an exact duplicate of an existing question.

I also would like to mention that when I cd into the external hard drive's directory and ls, it is empty – user149892 Apr 26 '13 at 18:42

Try to mount your drive manually with write permission

mount -t FSTYPE -o uid=X,gid=Y,umask=022 /dev/sdbX /path/to/mount/point

For your uid and gid run the following command

id your_user_name

To find out the file-system type

sudo file -s /dev/sdbX
