--- Comment #3 from Jun Itou <itou_jun@infoseek.jp> ---
Because it occurs in Debian7.7 and Fedora20, I think this symptom to be a
problem of kernel.
I confirm that I do the same operation in the following devices and reappear.

 I-O DATA HDZ-UE2.0TS
 I-O DATA HDZ-UE1.0TS
 I-O DATA HDZ-UE1.0TS
 I-O DATA HDW-UE

I was as follows in Fedora20.

Welcome to fdisk (util-linux 2.24.2).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
