Trouble reflashing micro sd card

Any adivce on reflashing my SD card. I am trying to reinstall shield OS from scratch to try and iron out any kinks and bugs it’s accquired over the years but I’m getting stuck at a message telling me the SD card is protected.


I’ve had that problem in the past with cards that have started to fail. If it’s definitely not a simple mechanical glitch with the write-protect tab, or an issue with the volume not unmounting, etc. (sometimes a simple reboot of the host OS does the trick) then it could well be that the card is dying.

how would I find out of it was a mechanical glitch or volume unmounting? Also what does a reboot of the OS entail?

By mechanical, I just mean giving the card’s physical write protection tab a few slides back-and-forth to make sure it’s not being read as protected.

The host OS is whatever you’re using to prepare the SD card (Windows, macOS, etc). Sometimes a reboot of your computer can clear up problems with reading and writing to the card.
