# Ubuntu – Can I write to a live USB stick

I'm trying to create a Live USB stick with additional files on it.
I created my live USB using Startup Disc Creator and I've tried to remount /cdrom directory as it described here but it answers

mount: cannot remount rw read-write, is write-protected


I even tried to write to the stick while I'm booted from my hdd, but with the same result:

fgh@fgh-box:/media/fgh\$ sudo mount -o remount, rw /media/fgh/Ubuntu\ 16.04.1\ LTS\ amd64/
mount: cannot remount rw read-write, is write-protected


I also tried

sudo hdparm -r0 /dev/sdc


doesn't work.

I would be grateful if you help me with making it writable.
