Sandisk 500 Just stopped Working

I am running Logig audio on an IMac and decided to save all my new album tracks to a SanDisk 500 as they would load faster. After faultless performance for 2 months today the mac couldnt mount the disc. Ive tried it on my other mac and neither can see the drive. This is potentially a disaster for me so has anyone any suggestions please

I purshaed mine in February 2017 and it just stopped working, yesterday. It simply stopped. My laptop does not find the drive.
