bmike1@c521 ~ $ e2label /dev/sde1 RedSanDisk
e2label: Permission denied while trying to open /dev/sde1
Couldn't find valid filesystem superblock.
so I graphically unmounted the drive and tried again:
bmike1@c521 ~ $ sudo e2label /dev/sde1 RedSanDisk
e2label: No medium found while trying to open /dev/sde1
Couldn't find valid filesystem superblock.
so I mounted it again and made a new mount pointÂ
bmike1@c521 ~ $ sudo mount /dev/sde1 /media/test
bmike1@c521 ~ $ sudo e2label /dev/sde RedSanDisk
e2label: Bad magic number in super-block while trying to open /dev/sde
Couldn't find valid filesystem superblock.
