Why did my SSD card stop working without warning?

Internal SSD Ultra® 3D SSD

My SSD card stopped working suddenly without any warning signs, and it’s no longer recognized by my computer. I’m unsure if it’s a hardware or firmware issue. Has anyone else faced this problem or know of any potential fixes? Any advice would be greatly appreciated!

Hi @harry_roy

It sounds frustrating! As others mentioned, it could be firmware, power issues, or hardware damage. Start by checking for firmware updates and run a diagnostic tool to see if the SSD is still detectable. If not, try the steps in the SanDisk troubleshooting guide shared by @suruguri.chaithanya1 . If nothing works, contacting SanDisk Technical Support would be the next best step.
