This morning I started MySQL Workbench and tried connecting to my default schema, but it wouldn't let me. So, I changed to a different schema and connected. I see that 2 out of 3 schemas are gone. I did not delete them. A couple of days back I was able to connect to the default one fine.

Is there a way to recover what is lost? I don't have a dump of those schemas. Volume Shadow Copy service was not running on my computer.

More info. In the ProgramData folder (where MySQL data is stored) I can see the folder for my schema with a bunch of frm files. Is there a way to restore these?

thanks a lot.
