I have a 2TB drive, formatted to Ext3, which I want to use to archive some recordings from my T2. The caddy is a USB3 one and I don't know if that is the problem, but I don't see the USB option when I press the "Media" button. If I use a 16Gb stick it sees it, and copies stuff across. I've not checked to see if it shows up on the Web IF yet, and I cannot do that now as I'm archiving to the memory stick at the moment. Any pointers please?
