[Bug 61966] Re: Usability: cannot change volume names

[Alessandro Gervaso]

I think that the label can be written only if the user has the permission to write directly on the block device and this isn't done by default.
If with "rw access to the drive" you mean rw access to the mountpoint I think it is the cause of the problem.
