does not recognise usb flashdrive

I have an early 2015 MacBook pro. It no longer recognizes my mini Lexar 32G flash drive. The drive works fine on a Windows 10 laptop. Any suggestions why this happened suddenly and how I can get it to work again?

Chances are the USB stick is failing. Windows is a lot more forgiving when there are issues.


Try erasing the whole physical USB stick in order to create a new partition table in addition to a new file system.


The quality of USB sticks is not that great so it would not surprise me that a USB stick could be failing or it may just have bit errors.
