Well what I mean is that by design is most probably not possible with actual software. If such action would be made then you would see partitions as separately folders.

It changes a piece of data stored by the kernel (which is also a piece of software) about the disk. When you attempt to write to a disk (hardware), it goes through the kernel's block device layer (software); the block device layer may refuse the write on the grounds that its policy for that block device is set to read-only. -- Colin Watson [<a href="mailto:cjwatson@ubuntu.com" target="_blank">cjwatson@ubuntu.com</a>] -- ubuntu-users mailing list <a href="mailto:ubuntu-users@lists.ubuntu.com" target="_blank">ubuntu-users@lists.ubuntu.com</a> Modify settings or unsubscribe at: <a href="https://lists.ubuntu.com/mailman/listinfo/ubuntu-users" rel="noreferrer" target="_blank">https://lists.ubuntu.com/mailman/listinfo/ubuntu-users</a> </blockquote></div>
