[Bug 1708881] Re: USB Stick corrupted - The driver descriptor says the physical block size is 2048 bytes

This regression bug also no long allows for persistent storage which was
useful for saving settings on the LiveUSB or special modules/drivers
that one would not have to re-download every time they load the LiveUSB.

Title:
  USB Stick corrupted - The driver descriptor says the physical block
  size is 2048 bytes

Status in usb-creator package in Ubuntu:
  New

Bug description:
  After using the usb-creator-gtk program the resulting Ubuntu 16.04.3 stick is corrupted.
  The error message when re-purposing the stick is:

  "The driver descriptor says the physical block size is 2048 bytes, but
  Linux says that it is 512 bytes."

  It seems like usb-creator-gtk is using dd without specifying the
  correct blocksize corrupting the USB stick.

  I've now lost 4 USB sticks on two different computers that I now can't
  format back to a usable stick.

  Steps to reproduce:
  Insert a blank USB stick into the USB port of the computer
  Run usb-creator-gtk with an Ubuntu 16.04.3 ISO
  Open gParted (parted, blkid, lsblk etc...)

  "The driver descriptor says the physical block size is 2048 bytes, but
  Linux says that it is 512 bytes."

  try to clean the disk with
  dd if=/dev/zero of=/dev/$USBSTICK bs=2048; sync

  again check the disk with gParted (or other disk utility)
  "The driver descriptor says the physical block size is 2048 bytes, but Linux says that it is 512 bytes."

  USB stick is destroyed.
