I have a Sandisk Extreme Go 64GB USB 3.1 Flash drive
It is not detected on Windows 10 but detected on Windows 7 (I have a dual boot, so can test on same port).
Also tested on a brand new Windows 10 laptop
Tried formatting to NTFS, ExFAT but same behavior on Windows 10.
I can see the drive in disk management in Windows 10 but cannot assign a drive letter

Anything I should check or try before requesting a RMA?

What's the exact error you're facing while trying to assign a drive letter under Windows 10? Have you tried diskpart to do the job so that you can get a proper error log?

This is the error I am seeing.
DISKPART> assign letter=R

DiskPart has encountered an error: The system cannot find the file specified.
See the System Event Log for more information.

DISKPART> clean

DiskPart has encountered an error: Access is denied.
See the System Event Log for more information.

I saw some suggestions on other forums on using linux tools to wipe the drive and then trying to format under windows. Will try that.
Though this works fine under windows 7 and only seeing the issue in windows 10

Since the drive works perfectly under Windows 7 (according to you), can you please take a look at the event logs under Windows 10 to spot the underlying cause of the error? Moreover, can you please post screenshots of the diskpart command sequences right from the beginning, i.e.:
Code: 
diskpart
list disk
list volume
and so on?

Just curious, have you ever tried locking it using BitLocker or making multiple partitions on it (e.g. as a Chrome OS recovery media)?
