VMB4000 Base station only seeing one USB flash drive

[Vinniemeatball]

I have had the unit for years now and am positive at one point both USB drives were showing in the app.   Just replaced cameras with new PRO 4’s and checked and now only one usb drive is showing.   What is odd however is the one that doesn’t seem to be working/showing, when I remove it I get a notification from the app that a USB was removed without being ejected properly.  

Any ideas ?
