Hi parted developers,

After having written an ISO image to my USB disk, parted gets really
confused. The USB disk is 64 GB, but parted thinks it's 257 GB! And
worse, when I try to reset the disk with "mklabel gpt" it throws
errors.

This issue is very much related to
http://lists.gnu.org/archive/html/bug-parted/2016-12/msg00016.html.

You can find the log of my parted session below my signature.

--=20
Best regards,
Bj=C3=B8rn Forsman

So in the end it seemed like parted managed to reset the drive, but
why make it so difficult?
