Years since I ever needed to work with an SD card. (It's possible I never have done so on this 6 year old PC.) But I now find that it is not recognised anywhere (File Explorer, Disk Management, Device Manager) ... except directly after a reset.


IOW, if I place it in its front panel port, Shut Down > Restart, then its drive F: is opened and I can work with its contents. But if I then remove it and return it or replace with any other SD card, then it's as if it doesn't exist any more.

This is Win 10 20H2 (19042.1348, the latest update available to me).

It's quite common for SD card hotplug on USB adapters to not work correctly. The solution is to unplug the USB connection once the SD card has been replaced, causing a USB hotplug rather than an SD card one. I suppose
that's a bit difficult if it's mounted in a front panel bay...

Try another SD card reader?

Thanks Theo. Coming regretfully to the conclusion that it's a long standing hw issue of the kind you describe. Maybe I've *never* had to use it until now, years on. Not skilled enough to attempt accessing it inside the case. Guess I'll
have to order an external SD reader.

Another thought: it's not a micro SD in an adapter, is it? If you pull the micro SD but leave the adapter in place, the reader doesn't see a hotplug
event because the adapter never moved (there's a detection switch inside the reader, although not all of them wire it up). If you pull the adapter and
swap over the micro SD before putting it back, that will trip the detection switch and hopefully cause a hotplug event.
