I wanted to format the system, but it didn't find any disk, so how I can disable storemi?
AMD StoreMI is based on Enmotus Fuze drive software.
AMD has stopped supporting AMD StoreMI but Enmotus.com is offering free StoreMI Support until May 15.
You can open a ticket with them from here: StoreMI Upgrade
