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

[EoflaOE]

I did it on Ubuntu Server ISO using usb-creator-gtk, using my general
USB flash drive and its size is 8GB, and it did the same thing so I
deleted the culprit partition using Gparted, and no errors like that is
displayed and it removed the partition completely, then, I was able to
create the FAT32 partition. From now on, I have to use Rufus, the
perfect tool on Windows.

usb-creator-gtk tried to set the flash drive's partition into ISO 9660,
which means it is not recognized by some systems, and is read only. I
removed the partition completely that is ISO 9660, then I formatted it
on FAT32 (partition size is 7.6GB after ISO 9660 removal).

So I suggest everyone who wants to create a Ubuntu flash drive must use
Rufus, or Universal USB Creator, until this bug is fixed to avoid damage
to your USB flash drive's partition.

Some users (like me) have this bug but they are able to remove the
culprit, iso9660 partition and recreating the FAT32, useful, read and
write partition. Others have this bug but they are not be able to remove
the culprit, iso9660 partition and shows that error.

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

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
