I can’t format my live-USB pendrive in ubuntu (udisks-error-quark, 11)

Open Terminal

sudo fdisk -l

This will list your all mounted/unmounted device..

Look for your USB device … you can cross verify it by from Disk utility…It may list something like

/dev/sdb1 or /dev/sdc1…

sudo fdisk /dev/sdb — if your USB is sdb

Command (m for help): d Partition number (1,2, default 2):

Partition 2 has been deleted.

Command (m for help): d Selected partition 1 Partition 1 has been deleted.

Command (m for help): w The partition table has been altered. Calling ioctl() to re-read partition table. Syncing disks

Now go back to Disk utility and then format the drive as you wish!
