MP 1,1-5,1 sd card not mounting

[glip]

I have an early 2009 mac pro 5.1 running 10.11.6. I have tried mounting 2 SD cards that both work in my laptop, but won't mount on my mac pro. I used the same card reader on both. I also have a card reader on my monitor, but that doesn't work either.
They worked last week on this mac. If I reformat them on the mac, it shows up, but then I need to reformat again for the camera and again it shows up in the disk utility, but won't mount.
Would appreciate any advice.
Thanks,

Have you tried connecting your camera directly.

I changed the usb wire and got the photos to show up in "Photos", but don't see the sd card (no name) to copy them.

Something is corrupted on my startup drive. When I restarted from another drive,the sd card showed up. Tried to fix from disk utility, but that didn't work.

Does card mount on another machine?

Test this:
Shut machine down. Let sit for 2-3 minutes cold.
Plug SD card reader into direct USB port on front of machine.
Boot machine to regular boot drive.
Does the card mount or show up?

Install DriveDx and check your system drive for issues.

I have been trying 2 sd cards; they both work on my laptop. Tried the shut down method and tried DriveDX with no success.
I have an old copy of disk warrior, but would need to buy an upgrade and not sure that would fix it.

Plug in the camera and open image capture.
All pictures should show up.

DriveDx is for your system drive, if you’re concerned there are issues.

Have had success with iBeesoft data recovery for Mac to get data off corrupted SD cards in the past. Does more than the “free” SanDisk software can.

In trying to reinstall El Capitan, I corrupted something else, so I restored from the latest backup and the problem is solved. The sd cards show up. What confuses me is that the backup I restored from should have had the same problem, but I shall not spend too much time questioning this unexpected fix.
Thanks for your suggestions.

I have had similar problems with most SD cards, and with most MacBooks I have owned. I also run into the not-mounting problem with my SD-card adapter. Usually breathing onto the connectors of the SD card itself (bringing the card close to my mouth and then speaking an open/aspired H sound onto it, to moisture the contacts) before plugin it in solves it.
