Hi There,
I Purchased SanDisk Ultra Dual Drive m3.0 32gb in 2019
It was working fine but now it is not showing any signs of life
I have tried to plug in my laptop Dell 3593 and my phone Galaxy J7 pro
But it doesn’t show disk or format problem

In Windows do you see a drive letter for the drive? If so open a Command Prompt as Admin and run a chkdsk /f for the drive. Something like: chkdsk /f e:
If you don’t see a drive letter you can try this :
diskpart * Run Command Prompt with Admin Rights.
list disk
…
select disk 1 * Note: disk nbr is the nbr of the USB disk
clean * This DELETES Everything on the disk
create partition primary
exit
Then format the USB drive as exFAT.

After confirming that the USB port and cable connections are not the cause, open Disk Management to see whether the USB drive is detected (right-click the Start menu and choose Disk Management). If the drive shows up but does not have a letter assigned, right-click the volume and select Change Drive Letter and Paths, then assign an available letter like F: or G:.
If that doesn’t resolve the issue, you can try updating or reinstalling the USB controller drivers, running a disk repair utility to check for errors, or verifying in the BIOS settings that the hard drive is enabled and properly recognized by the system.
