I'm thinking of resetting my SD-1 to original factory setting but I'm afraid that I will lose the midifiles in the hard drive. I've saved all the registrations I've made. It has been updated from 2.0 to 3.0b.
The reason I want to rest to factiry default setting is I am hoping that the occasional problem of not turning on will go away. Please give me some advice.

You will not lose anything off of your hard drive . dano
