SanDisk USB drives

Thank you for the reply Roger Faust!

Let's try booting in safe mode once more. If the issue persists, the actions in this article can help resolve USB devices not working with your Mac:

If a USB device doesn’t work with Mac

"If a USB device doesn’t work with Mac

If a USB device isn’t working properly, make sure it’s connected to your computer correctly, is plugged into a power outlet if it has a power cord, and has any necessary software installed.

• Check the power, port, and cable connections: Make sure the USB device is turned on and its cables are properly connected. If your computer has more than one USB port , switch the device’s cable to another port. If you still can’t use the device, contact the manufacturer for more information.
• If you can use the device after switching ports, connect another device to the first port. If you can’t use this device, shut down the computer and unplug it from the power outlet. Wait about a minute, then plug it back into the power outlet and start up your computer.
• If you still can’t use a device with the port, your computer may need to be serviced. See Find out how to service or repair your Mac.
• Check for missing software: Make sure you installed the latest software for your device. Visit the manufacturer’s website for any updates.
• Check the USB hub: If the device is connected to a USB hub, make sure the device and the hub are the same speed. Connect USB 3.0 SuperSpeed devices to a USB 3.0 SuperSpeed HUB, USB 2.0 Hi-Speed devices to a USB 2.0 Hi-Speed hub, and so on.
• If the device doesn’t have a power cord and is plugged into another USB device that doesn’t have a power cord: Try plugging the device directly into your computer’s USB port  or into a USB device that does have a power cord. You might need to disconnect and reconnect the other device as well, if it has stopped responding.
• If you have many devices connected to your Mac: Disconnect all USB devices except the device you’re testing, an Apple keyboard, and an Apple mouse. Make sure that the device is connected directly to the computer, and that any hubs or extension cables are disconnected. If you can use the device now, the problem may be with one of the other USB devices or hubs you had connected to your computer. Try reconnecting them, one by one, to your computer. When you find the device causing the problem, review its documentation for further troubleshooting steps.
• Verify that the device appears in System Information: On your Mac, press and hold the Option key, then choose Apple menu  > System Information.
• In the window that appears, see if the USB device is listed below Hardware in the list on the left. If the device appears but does not work, review the device’s documentation for further troubleshooting steps.
• Reopen apps: Quit and reopen any apps that use the device.
• Restart your Mac: Choose Apple menu  > Restart."

If the issue persists after completing those actions, reach out to Apple directly to investigate:

Hello there Roger Faust,

Welcome to Apple Support Communities. We suggest booting the Mac in safe mode to help with this. Doing so isolates any issue that may be caused by a specific app. Follow these steps per the Apple Support article: How to use safe mode on your Mac

Intel processor

1.Turn on or restart your Mac, then immediately press and hold the Shift key as your Mac starts up.

2.Release the key when you see the login window, then log in to your Mac. 

3.You might be asked to log in again. On either the first or second login window, you should see ”Safe Boot” in the upper-right corner of the window.

The article also contains guidance based on whether or not the issue persists in safe mode. Let us know if you have any questions.

We hope this helps you.

last Monterey version now is 12.6.2 , this is still little bit more buggy (at this point of time Dec 2022, Jan 2023), than the older 12.6.1 version.

so please again update & test your SanDisk USB Drive in Monterey specific version 12.6.1,

in Monterey 12.6.1 it should work fine.

See more info to get specific version ( use "12.6.1" in command-line , instead of 10.15.7 shown there).

Or wait for Monterey 12.6.3, hopefully in that version it will work fine.

different mac computer has different hardware configurations, and on top user has own/different configurations/choices , etc , so there can be buggy activity activated in one mac computer but not in another computer , ... anyway , i'm sure apple devs are debugging & solving these issues, to address these variances, to achieve same expected safe functionalities.

Hello Roger Faust,

Well, it seems you have 2 issues. The third-party drive and now your computer can't get into safe mode.

Please contact Apple Support, so they can check into what's happening further: Contact Apple Support

Thanks.

Hey Roger Faust,

We're so glad to hear the issue has resolved itself. Thank you for letting us know.

Take care!
