Micro-SD issues

[AHarvey]

Not sure where to put this but figured here is best.

I've a 64gb MicroSD that i photographed a wedding on to 2 months ago, worked fine.

I've gone to format it in my Nikon D810 on Thursday and it failed, states it's locked.

I've tried it in a new adapter that i'd just used to format another and it failed again.

Popped it into the PC and it doesn't show in explorer, but does in diskmanager, but I can't do anything with it as all the options are greyed out.

I've installed SDFormatterv4 as suggested online, if I run the software with the SD already in the laptop it doesn't actually load. If I remove the Sd it'll load, but as soon as the card is put in the laptop the software dies.

If the SD is in the camera I can see all the photos indicating I can still read from it ok, none of the photos are locked. Any suggestions on how to proceed?

Look to see if there is a write lock switch on the side of the card.

There isn't on the micro-Sd and the adapters have them but I've tried several and locks are off on them all.

Thanks @Danny091 I've just tried and it threw the following error.

DiskPart has encountered an error: The request could not be performed because of an I/O device error. See the System Event Log for more information.

Checked the Event Viewer and can't see anything related.

I've a few more things to try from a google search regarding this error but it's looking like the card may be faulty as it's just not recognised in the laptops etc but only the camera.
