Resetting MySQL


I’m having a problem with the MySQL database running as a DroboApp on my Drobo5N. I want to completely remove the database and set it up again from scratch, I tried doing this by removing the MySQL DroboApp and reinstalling it, but when I start it up again my database is still present? I’ve had a poke around on the filesystem but can’t find where it’s storing this database.

How can I completely remove MySQL from my 5N?
