USB memory stick is broken on my laptop, but works on the 3D printer!

I am having this issue with a USB memory stick, and I am wondering if anyone else has run into it and has been able to salvage it. I don't need the files on the USB stick, I just don't want to have to throw it away!

It happened without warning and I'm not sure that I did anything that prompted it. It was working one minute, and the next it was broken.

When I plug the USB stick into my laptop (Mac Tahoe 26.3.1), it seems to mount okay, but the Finder window shows endless loading swirlies where the files would be listed. When I click "eject" it doesn't un-mount. In Disk Utility, the drive shows up, but attempting to erase, reformat or repair it results in a failure message, and the explanation is that it couldn't unmount the drive.

This happens on two different laptops, both Macs. It also happens in Disk Utility in recovery mode. I have restarted my laptop, I have force-quit Finder, and I have tried using Terminal instead of Disk Utility - all have the same outcome.

However, when I plug the USB stick into my 3D printer, the .bgcode files show normally.

Has this happened to you? Were you able to fix it?

RE:

Memory sticks are consumable items. Just get another one. Or use a Micro-SD with an adapter.
