Title:
  gparted does not recognize the iso9660 file system in cloned Ubuntu
  USB boot drives

Status in GParted:
  Unknown
Status in gparted package in Ubuntu:
  Triaged

Bug description:
  I am testing in a live system and looking at the very drive, from
  which it is booted, the current daily iso file of Lubuntu Xenial i386
  (post 16.04.1 LTS). The problem is that the file system cannot be
  identified, and several end users may (and will) think that the USB
  boot drive is damaged. But it works, it is cloned, which is the
  straightforward method to create a boot drive from a hybrid iso file.

  this issue was worse in previous versions, where gparted would
  complain about an error; now it is at least seeing the partition. The
  next step is that it can see the file system too.

  lsblk can see it, as illustrated by the following command line (in a
  wide terminal window),

  sudo lsblk -fm

  The attached screenshot illustrates the problem, and shows that it
  affects the text mode program parted too.

  UpgradeStatus: No upgrade log present (probably fresh install)

  Edit:

  After some testing I found that the current i386 versions behave in a
  similar way as Xenial.

  But the current amd64 (64-bit) versions are more severely affected by
  this bug. It is much worse in Trusty, but also bad in Xenial as
  illustrated by screenshots in comments #6 and #7. This behaviour will
  really confuse new users of Ubuntu and the Ubuntu flavours.
