[Tails-dev] Creating a persistent volumn

Problem in creating persistent volumn on usb drive

Installed and running tails on on usb drive. Now once in tails trying to
create a persistent volumn on second usb drive. (Note the second drive had
files which were copied to external drive and deleted from second drive)

Problem Choose Applications > Tails > Configure Persistent Volumn and then
received Error message

Error
Device /dev/sdb was not created using Tails Installer.

What do I do now? Thank you.
