Files I delete on my USB flash drive keep coming back
I have a USB flash drive with a SanDisk MicroSD card in it, and whenever I delete everything on it the files just keep coming back whenever I plug it back into my computer. This never happened before so I'm not sure what to do. I tried right clicking on the removable drive and formatting, but I always get a message that says "Windows could not format this drive." Same thing happens when I go under disc management and try to format it from there. Also, when I right click on the drive the option to delete partition is grayed out.
Anyway, if anyone can help out in anyway I would be really grateful. This has really been driving me crazy.
