How did you set the ownership of the partition devices in the first place? You can't just manually set the ownership and permissions of device nodes, you need to use udev (which is responsible for creating them) to do that. parted tells the kernel to rescan the partitions, so the device entries are probably being recreated by udev, changing their ownership back to whatever udev thinks they should be. -- Brian C.
