I have a 2.5" 960GB Sandisk Ultra II SSD mounted inside an external enclosure. It recently died on me. MacOS won't recognize it when plugged in. I tried 2-3 different machines and no luck. It was acting funny the day before it died meaning some files were missing and taking forever to access. Is there any hope in fixing this or is it dead for good? Just wanted to see before I smash it and chuck it in the trash. Thanks
