Windows 10 wants to format my Rockboxed Sansa E250

[clutch]

Recently my Win7 box expired and I replaced it with a new one running Windows 10 Home.  Now when I connect windows wants to format the 20M partition that I assume has boot loader stuff in it.  How do I get Windows to stop wanting to format it?

Thanks,

If you get a 20MB raw partition it means that the player couldn't load the firmware from the storage.

Does the device actually work?  Usually it will be semi-bricked in this state.

It works great, I've been using for years.  I took another E250 that I have rockbox on and I get the same offer to format the 20MB partion on that one also.  Here is a picture from drive management.
