Agreed.

It would´t be the first time that I'm misinformed from a Mexico-Apple rep or repair person. This would actually be like the 12th time

What I assume they mean is that the drive parks when it senses motion as long as it remains parked of the full duration of the computer nap, but I think they think ( ! ) it parks for a moment and then it un-parks an so on constantly... Could that be it?

Seems to me if the head is parked and the disk is powered down, the head is not going to move until the power comes back up, and the motion detector is irrelevant once the Mac is in sleep mode, because there is no power to anything but the RAM. Your post led me to look through Apple support, and I can't find any advice from them. But here's an article that addresses the question directly, although I have no way of knowing if these people know what they're talking about.

You mean like the Mexian Apple reps?


I'll read the link and check what they say...

They also said that the HD seems damaged with lots of faulty sectors.

I was expecting that from your symptoms as you can see from my first response. That matched your symptoms perfectly.

Is this old enough to have a Seagate HD? Ignore the techs who tell you that she caused this by carrying it in Sleep mode. You really shouldn't move one before its gone to sleep but people do all the time without harm.

Certain Mac Books are known for motherboard issues. A bad drive can cause them. If this has an optical drive, that can be the culprit. Sounds weird that an internal DVD burner can cause motherboard issues but it's true.

If you have the opportunity to pick up a new one with no moving parts except a cooling fan, that will be ideal. My wife'e MacBook Air is a great machine.
