:smiley:   Hi Shellbye30,

Dear member of SanDisk Community, welcome.

[.…then now is not even showing up on computer or on device. ]

Mmm… Sorry_, if not recognized, implies that died._

Test your card, in other laptops, directly to its port-card (not USB card-reader), and see what happens.

If still bad, do not grieve more, contact SanDisk Technical Support who will replace the card, if it’s authentic and is within warranty.

Luck, and then you tell us, what happened, please.
