We saw this with AIT drives. Someone got it wrong again.

The workaround given was to use format=drive rather than format=aitc on the
drive definition. We're waiting for the proper fix just in case there are
some more gotchas round the corner.

Kinda niggling these things.......I know the developers are under pressure
to deliver and the new functionality each time is most welcome but there's
always something old which is newly broken each release.
