How to remove write protection/read only on usb flash drive?

[Ken J]

I have an adapter for my microSD. I try to copy something onto it but a message appears saying "Remove write protection or use another drive" and it when I check out the properties on the folders it says "Read Only" and it is activated. When I try to deactivate it an error comes up.
I tried the StorageDevicePolicies in regedit -dont work
I tried removing read only check -dont work
I tried CMD "attributes clear readonly" -dont work
someone please help me
all answers are appreciated
People this is not an SD card its a MICRO SD which means it has NO switch

look closely at the flash drive, you should see a tiny switch to get it off write protected
