Firstly, it is not good policy to shut down daily. It is a subjective matter but that is the consensus I see in these columns. Once a week should be sufficient for the costs are insignificant in energy usage. Use sleep.
The best resource for Time Machine questions is Pondini FAQ.but turning things on and off repeatedly is not good practice. You should just leave it on to do its job in my view.
Seems like with everthing there is this constant disagreement between it is best to turn things off (let them rest and save energy/$) vs keeping on for best function.
THANKS for your time and I will take your adveice!
Do you know why the MYPassprot makes "light flashes" when I see it in a dark room? Sounds crazy but it looks unhealthy!
As I said, the amount of energy used is insignificant.
But the constant turning on and off can be detrimental to your machine. That is why I always use sleep. Indeed, unless I am away for a few days I never turn my iMac off.
No, I don't know why My Passport flashes as you describe. I assume this is the Western Digital passport external HD (good choice, I use Western Digital too). Why not eMail the WD service centre and ask?

I just called WD as I am still in my 30 day free support. They said as long as the light is solid or flashing it is fine.....no light is a problem. It may be coincidental but for some reason I slightly moved the hard drive to see it better and it stippped flashing and started solid light. She basically said it flashes when "working" and solid for stand by. I read that many hard drives flash wshen not working so I was concerned but my TM reports it is transfering fine.
Hope this helps soemone, and I appreciate all your help!
