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. -- Best regards, Bjørn Forsman $ sudo dd if=ubuntu.iso of=/dev/sdb bs=1M $ sudo parted /dev/sdb GNU Parted 3.2 Using /dev/sdb Welcome to GNU Parted!
