Help, I have messed up my USB! ! !

USB

Info:
running debian 8.10
LINUX
And it was working (but only read-only) before I deleted it
It is write protected (I would like to read and write)

A while ago, I installed Linux cinnamon-64 on my PC using this USB. I tried to use it for files (you know, move files onto USB and out onto different PC or whatever) and I tried to reformat it. I used GParted to delete the Cinnamon-64 that was still on there (couldn't delete it manually as it was read-only) and I deleted the other code as well which I think was the code for mounting to computers because now, when i try to view the files, it comes up with this error:

Error mounting /dev/sdc1 at /media/mixtli/LMDE 2 Cinnamon 64-bit: Command-line `mount -t "iso9660" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000,iocharset=utf8,mode=0400,dmode=0500" "/dev/sdc1" "/media/mixtli/LMDE 2 Cinnamon 64-bit"' exited with non-zero exit status 32: mount: /dev/sdc1 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/sdc1,
missing codepage or helper program, or other error

In some cases useful info is found in syslog - try
dmesg | tail or so.


FIXED:
I needed to do sudo hdparm -r0 '/media/mixtli/LMDE 2 Cinnamon 64-bit' to set read-only to 0 (false) then i did the tutorial. Thx for ur help!!

What I have tried:

I have tried dmesg | tail and it comes up with this:

I have also tried the tutorial in the first answer. when I did mount /dev/sdc1 /media/usb-drive/ it came up with this:

mount: /dev/sdc1 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/sdc1,
missing codepage or helper program, or other error

In some cases useful info is found in syslog - try
dmesg | tail or so.
