the console gives me the feedback that I have no permission to operate /dev/sdc1, what does it mean, should I input the password of the device, and how?
And stranger_st said this approach needs no password.

Maybe it's you lack knowledge of how UNIX/Linux works.
You need to be a superuser (aka root). Ubuntu uses sudo as a way to get superuser privilieges per default. Ubuntu (mistakenly in my opinion) uses the user password to get root privilieges, so you need to use that in order to do certain operations.
Per default, modifing and mounting file systems aren't allowed by standard users.
