i have tried to change my microSD card to a bootable nanoDLP for my pi. but the card reader i used moved or something, and the process stop in an error, trying to reformat i put the microSD back to the PC, but it was not recognized and i got the "please insert a disk into usb drive" error. i have tried to reformat by using the techniquein this question or in this guide and many other guides, that all show the same techniques. non of this technique worked, all show as this disk is empty, and nothing is connected. can i do something on the hardware level ? or any other techniques that i haven't tried ?

  • The best would be to replace the card and avoid doing again what killed the previous one. Mind you, the timing of its death might have been just a coincidence.
