[Bug 1589028] Re: Improper blocksize set by usb-creator, leads to problems during formatting

[sudodus]

The problem is that some tools do not recognize the hybrid iso file's
internal structure when cloned to a USB drive. This has been a standard
for iso files that can be cloned to CDs, DVDs and USB drives (actually
any mass storage drives including memory cards SSDs and HDDs).

The Ubuntu Startup Disk creator is only doing the cloning job like
several other tools and should not be blamed for this problem.

Fortunately new versions of gparted can recognize USB drives that are
cloned from hybrid iso files.

There is an easy fix, if you want to use other tools: mkusb has a
dedicated menu option to restore the USB pendrive to a standard storage
device,

Title:
  Improper blocksize set by usb-creator, leads to problems during
  formatting

Status in GNU Parted:
  New
Status in parted package in Ubuntu:
  Confirmed
Status in parted package in Debian:
  Fix Released

Bug description:
  When ever I create a bootable USB using usb-creator , and when I try
  to format it after my work is done, I get this error

  “The Driver descriptor says physical block size is 2048 bytes, but
  Linux says it is 512” in Gparted. (screen shot in the attachments)

  Furthermore , The USB is divided into strange partitions (image
  attached). and shows the 16GB partition as 60GB partition.

  I presume that this is because of setting the blocksize to 1000000 by
  this tool : as in the source code here : https://bazaar.launchpad.net
