SANDISK ULTRA FIT USB 3.0 FLASH DRIVE and the new MacBook Pro

Hi, i tried to use my Fit 128GB flash drive on a new MacBook Pro. I was transfering a 20GB file and the Flash Drive over heated and the transfere aborted after 50%. It was not possible to hold it, to warm. Known bug?

It works perfectly on my 2015 MacBook Pro.

I have a Ultra 128GB flashdrive that I tried to use to craete a backup of my HP laptop and for whatever reason (I think) the HP system (Windows 10) reformatted my drive to 32GB!  Now I can’t seem to be stuck with a 32GB SanDIsk Ultra USB stick!  How an I reset it to the original 128GB?
