[Bug 1059872] Re: Error formatting disk using disk utility

[NoBugs!]

How is this broken after at least two years? Or is it meant to scare
beginner users that may have chosen the wrong setting, choosing "format"
drive, this is considered to be really a command-line-only task?

Bug description:
  [Impact]

  Formatting a SD card using the disk utility fails with an error
  message

  "Error formatting disk - Error synchronizing after initial wipe: Timed
  out waiting for object (udisks-error-quark, 0)"

  The underlying problem is that the "wipefs" tool from util-linux does
  not work any more.

  You can work around this bug in gnome-disk-utility using these steps:

  * After selecting the SD card, instead of clicking the gear icon to format,
    click the partition in the "Volumes" section.

  * Delete the partition ("minus" icon)

  * Create a new partition

  [Test Case]

  $ sudo modprobe scsi_debug dev_size_mb=200
  # this creates a new /dev/sdX, usually /dev/sdb; check dmesg!

  # now create a partition table
  $ cat <<EOF | sudo sfdisk /dev/sdb
  # partition table of /dev/sdb
  unit: sectors

  /dev/sdb1 : start=       32, size=   409568, Id=83
  /dev/sdb2 : start=        0, size=        0, Id= 0
  /dev/sdb3 : start=        0, size=        0, Id= 0
  /dev/sdb4 : start=        0, size=        0, Id= 0
  EOF

  # now create an ext4 file system:
  $ sudo mkfs.ext4 /dev/sdb1

  # check contents:
  $ sudo blkid -p /dev/sdb /dev/sdb1
  /dev/sdb: PTTYPE="dos"
  /dev/sdb1: UUID="4bd1c542-a61f-43c4-a7e5-cc50e66e6b5a" VERSION="1.0" TYPE="ext4" USAGE="filesystem" PART_ENTRY_SCHEME="dos" PART_ENTRY_TYPE="0x83" PART_ENTRY_NUMBER="1" PART_ENTRY_OFFSET="32" PART_ENTRY_SIZE="409568" PART_ENTRY_DISK="8:16"

  # wipe:
  $ sudo wipefs -a /dev/sdb

  # now check contents again
  $ sudo blkid -p /dev/sdb /dev/sdb1

  # in the broken case, you will still see a "dos" partition table and
  the ext4 partition; in the working case, /dev/sdb won't show anything
  and /dev/sdb1 does not exist any more
