I have just go around to setting up time machine. I have a hard drive (PC, internal type) in an external caddy. I deleted all the old stuff & made the backup overnight. That has worked fine, but I have 2 questions... I have a second internal drive in the same caddy & a USB drive plugged in to the mac as well. The backup ONLY "backed up" the mac 1TB internal drive. Can I backup the other 2 drives as well? Secondly....as its an internal drive/caddy, is it safe to remove it (i.e. switch it off) as its quite noisy & also fear that if it running 24/7 it will fail. If turning it off, I assume I drag the logo into the recycle bin, in the same way that I did previously (when the logo was "1TB external") Any help, much appreciated.
