It should be "fdisk /dev/sde" instead.

Now that's strange - there should not be partitions within partitions.
Probably fdisk thinks, the data from the first sector of that partition
must be a partition table (which is wrong).

Glad it didn't work - I suppose that was close to a disaster.

No, the USB connection is OK. Just use the correct name for the devices
you want to use, i.e. /dev/sde for the fdisk command. And before you
format a partition, umount it, if it is mounted.
