sd card restore

[corvairbob]

i have a few sd cards and they just will not work. i have tried all i know and also all i found so far online. they will not work in the phones or the chromebooks or the pc laptops. i have tried on the pc using the command window to see them and nothing. there must be a say to see them and if i can see them i may be able to bring them back to capacity. anyone had any lock getting dead sd cards back to life? thanks

I know there's software that is meant to help, but I personally have never used it before, so I cannot help I'm afraid. But one time my laptop could not recognize the SD card, and I though it was corrupted. Tried it on a different one, and it was recognized. After formatting it, the first one recognized it as well. Sorry I cannot be more help to you.
