I use the sandisk extreme with my mac book pro osx 10.8.5. I have used these two together for about 8 months.
The sandisk just quit working. My mac and two other machines don’t recognize the sandisk now. I have several files on this sandisk drive that i would like to recover.
Other than always make sure you have a backup,or two,of important files, no. Based on what you said the device is dead. A local tech repair shop may be able to offer better advice after looking at it.
