Hi all,
Never had this problem before, but external drives are really tempermental at the moment. They either don't get recognised at all, or if they do and I mount them and try to copy data, they just drop out, my copy fails and I can't mount them again.
I noticed when I log out it says "maybe a bad usb cable" but I've tested it on other machines and it's fine.
Maybe there was something I didn't do in the transitions to systemd? I'm using XFCE Sabayon.
