Partitions … have been written, but we have been unable to inform the kernel of the change, probably because it/they are in use. As a result, the old partition(s) will remain in use. You should probably reboot now before making further changes.
This is happening in both gparted & gnome-disk-utility on all of my disks (OS, data1, data2, etc…). Rebooting and then using either program results in the same error.
I’ve never had this error before, and I don’t want all of my harddrives ruined. What should I do?
