Hi Pascal,

I am nervous about running wipefs. Especially since its man page does not 
match is operation. plain wipefs doesn't show anything while the manpage 
says it should.

file -s thinks the swap partitions are data?

----------------------------------

address@hidden:~# file -s /dev/sda2 /dev/sdb5
/dev/sda2: data
/dev/sdb5: data
address@hidden:~#

----------------------------------------

  fdisk thinks there are swap partitions.

---------------------------------------

address@hidden:/home/user# fdisk /dev/sdb
