In addiction I'd suggest to use the so called "exit status variable: $?" 
in the "if ; then" statement:

...
echo "working volume assigned a value; now try blkid."
blkid -t UUID="$workingVolume" >/dev/null 2>&1
if [ $? -ne 0 ] ; then
   printf "workingVolume not found.\n"
else
...

it makes the code more readable, IMHO.
