Lexar SSD not recognized on MacBook Pro M4 Pro

Hello everyone !

My Lexar Professional Go Portable SSD doesn't appear anymore on my Mac (Macbook Pro - M4 pro).

I use it everyday for work, but since this morning when I plug it nothing appear, but the usb ports are working with other devices. So I tested the Lexar on a Windows device : It's working.

I tested it on TAHOE 26.0 (25A354), then updated to TAHOE 26.3 (25D125) and nothing is working for my Lexar.

Anyone has a solution? The disk is not recognized even in the "Disk Utility".

Thank you for reading me !

MacBook Pro 14″, macOS 26.3

What file system is on this Lexar SSD?

If it uses the NTFS file system and you have installed third party software to manage the NTFS file system, then you will need to make sure to update that software since a macOS update patch can easily break third party drivers. If you are using the latest version of that third party software, then contact the developer of that software for assistance.

a drive that will not reveal its make&model and a reasonable non-Zero Size/Capacity in Disk Utility when The tiny "View" menu is set to 'show all devices' can not be used in it current setup.

if it is getting enough power, it has failed.

You can use

option-Apple Menu > system information > hardware > USB to check its power:
