Hello all,

I have an internal WD 100GB HD that I put into an external USB case for more storage in my Mac Mini. However, it's noisy when it's not doing anything. The indicator light isn't blinking but it sounds like the platters are spinning. Does anyone know why this is happening?

Thanks!

Is it possibly the external's case fan you're hearing? Don't mean to insult your inteligence but many cases have fans and since you didn't say I thought I'd throw that out there.
Never argue with an idiot. They'll drag you down to their level and beat you with experience.

No insult. I would conclude the same thing except it's not constant. The sound is more a HD working and isn't running in any sort of pattern that I can decipher.

It sounds like the platters are spinning, because, well, they are.

Yes, but my question is why? I'm not accessing it. It only contains files not programs that may be running and I haven't set it as any scratch disk. What is OS X doing with it?

Unless you've set the hard drive to sleep, hard drives are always spinning so they are ready for you to request data.
