Hello Inf0Nepal, The Recovery Guru is installed when you install MDSM.  The guru is meant to provide a point of reference & assist a dell technician with troubleshooting any issues with the MD.  You can see the guru by going to the Summary tab in MDSM and it will display some test of errors if there are any.   Please let us know if you have any other questions.
How can we download this recovery guru software and what is it meant for?
