** Description changed:
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)"
Steps to repro:
Launch the disk utility
Plug a SD card into the computer
Select the SD card and click on the gears icon at the top right of the
application
From the drop down menu, select "Format Disk"
maintain the default setting and select Format
Acknowledge warnings
After format process has been going for a while, the error message shown
above pops up
+
+ Workaround:
+ 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
-----
The underlying problem is that the "wipefs" tool from util-linux does
not work any more.
=== 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"
+ /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
