Micro SD not recognised

I bought a SanDisk 32gb micro sd card to beef up my phone that kept running low on memory. It worked fine for a couple of months, then stopped being recognised.

I’ve connected it to my laptop via a usb adapter and still can’t seem to ‘find’ it. The usb drive shows up below the Hard Disk and the CD/DVD Drive, but with no ‘size’ or ‘contents’. In Gparted it doesn’t show up at all.

What d’ya reckon? Is it fecked?

If anyone has any ideas on how to perhaps fix it, I’m all ears. There’s nothing special on it, so anything is worth a punt.
