Another DeepSleep Widget
I made a free widget that hibernates your Mac as well. You can get it at http://www.axoniclabs.com/DeepSleep/

The default sleep state can be risky for transport as the Mac can wake to perform scheduled maintenance tasks. During maintenance the read arm of the hard disk is no longer locked and if shaken can touch the hard disk causing read errors potentially corrupting the disk. Mac portables do have technologies that protect the hard disks from motion but they are not 100% effective.
....huh?
I leave my 2007 MacBook in sleep all day in between classes and on my way home, and even during cross-country flights and multi-hour drives, and rarely ever see it lose more than a few percent battery, if that.
Provide links to Apple's site that support this statement. You can't, because it's not true.Intel Macs have three possible sleep modes:
Again, not true. Mac OS X has Wake On Demand, but that doesn't apply to a sleeping Mac portable being transported.The default sleep state can be risky for transport as the Mac can wake to perform scheduled maintenance tasks.
While I understand your desire to be cautious, posting things like this only serves to mislead and confuse forum readers who want actual facts.That info could be wrong and I am in error presenting it on this forum but I prefer to be cautious given the consequences.
If the fans are running higher than normal at the time you close the lid, your Mac will not sleep until the fans have cooled it to a level safe for storage or transporting. If you wait until it sleeps (and the sleep light is pulsing), the fans will not spin up again after it sleeps.I just searched the threads for info concerning this and apparently there is a risk that a sleeping Mac will wake itself to run it's fans if it is put away hot in an environment such as a padded computer case or backpack.
Again, Mac portables do not have a hibernate setting. They consume approximately 1% of battery power per hour of sleep.Also, if you do not want to your Mac to consume power while sleeping, you have to manually set it to hibernate.

If the computer is asleep at the designated time, a launchd job executes as soon as the computer wakes. This is similar to the behavior of anacron and other cron replacements).
I do believe that I stated I could be wrong about the waking from sleep stuff?
Sorry? What does it really matter.
People use these threads to discuss issues and gain knowledge about their multi-thousand dollar machines.
Can't guarantee that's how every app is programmed though, some may be poorly programmed, and wake the computer up, although I've never seen it.
Scenario A vs. Scenario B
Scenario A = I am right and users can damage their hard disks while transporting a sleeping Mac.
Scenario B = I am wrong and user unnecessarily turn off or hibernate their Mac during transport. So, no harm done.
Sorry, but why does what I said really matter. No harm could come from Scenario B. The only downside is they lose a few more seconds of their life waiting for their computer to start up. OMG that's terrible.
The harm comes from misinforming people, encouraging them to go through unnecessary steps, just because your opinion is that it's safer. There is nothing unsafe about transporting a sleeping Mac portable. In fact, you can't damage your hard drive by moving your Mac even when it's awake, because of the sudden motion sensors.
Really? Make a YouTube video of you shaking your Mac as hard as you can while it is awake. Even better, mount it in a paint shaker and leave it there for two minutes.
Post the link to the video, then I will believe you.
Sudden Motion Sensor technology is built-in protection for the hard disk that is designed to help prevent disk issues if the computer is dropped or undergoes severe vibration.
The Sudden Motion Sensor is designed to detect unusually strong vibrations, sudden changes in position or accelerated movement. If the computer is dropped, the Sudden Motion Sensor instantly parks the hard drive heads to help reduce the risk of damage to the hard drive on impact. When the Sudden Motion Sensor senses that the Apple portable's position is once again stable, it unlocks the hard drive heads, and you are up and running within seconds.
The point is, transporting a Mac portable, asleep or awake, is NOT going to damage the hard drive. That's transporting.... not throwing across a parking lot, strapping to a jackhammer, mounting on a paint shaker, etc.Sudden Motion Sensor technology is built-in protection for the hard disk that is designed to HELP PREVENT disk issues if the computer is dropped or undergoes severe vibration.
Nothing is 100% guaranteed.Help prevent does not equal 100%.

You've obviously have never been on a plane during bad turbulence or on a ferry during rough water.
These situation are why people are switching to solid state drives.
You don't know what flights or ferries I've been on, or in what conditions. Look, if you want to shut down your Mac before transporting it, that's your call. Just don't try to deceive people in this forum into thinking that it's unsafe to transport a sleeping Mac. I've also transported sleeping Macs on my Harley for thousands of miles with zero issues.
You're being deliberately obtuse and now going off-topic, but yes, I ride a Softail and have ridden many Harley models over several decades. Which model is irrelevant, since the vibration of bumps on the road is much harsher than the engine vibration. The point is, it's quite safe to transport a Mac notebook in sleep mode. Period.I take it you don't ride a Softail with an Evo motor nor an old shovelhead FX or FLH. I love those old shovelheads but you really need an FLT/FLHT prior to 1984 to avoid the vibes unless you like them.
