Hi,
I have two 1TB Toshiba USB drives connected to my laptop. They dont have "sleep mode". One is for backup the other one is for iTunes library and photos. Sometimes I'm running comp all night downloading stuff etc. Shall I keep drives "on" all the time or "eject" them and power them down every night? I'm not sure what is the best option here
Don't want to accidentally destroy them by endless circle of "on and off" 
Thanks
Dan
