SD card not showing up on MacBook
I have an adata brand 16 gig SDHC card which became corrupted in my Canon S90 (it looks like a lot of people are having problems with this card). When I put the card into the card reader, the volume does not show up on the desktop of my MacBook Air 2017, or appear at all under Finder -- no error message or any other evidence that it is attached in any way.
I have done some basic troubleshooting in this post: https://iboysoft.com/mac-data-recovery/sd-card-not-showing-up-on-mac-computer.html
I've tried to show the SD card on the desktop and in Finder, but to no avail. Then I've checked the SD card in Disk Utility, but I couldn't be able to see it listed on the left sidebar.
I have also tried a variety of card recovery programs on my Mac, like Photorec, EaseUS, iBoysoft. And on the Windows side booted under VMWare. But since the card is not mounting at all, none of these programs can see the card to try to recover anything.
Does anybody have any suggestions? I really would like to recover these photos.
