WARNING!

If you want to use this internally, HD's with the G-shock protection seem to conflict with Apple's implementation of G-shock protection--resulting in extremely large numbers of head loading and off-loading (i.e, hard drive heads being parked and started and parked and started, etc.

For example, the load cycle count on the 320GB WD WD3200BEVT I took from an external enclosure is 704,575! And the power-on hours is only 6,300! In other words, the heads have been parked more than 100 times per hour.....

I believe this is the explanation for the extremely high load cycle count for Apple laptops that has been reportedly widely around the Interwebs.

According to wikipedia, disabling the SMS in the MB/MBP should eliminate any conflicts:

wikipedia wrote: Among the MacBook and MacBook Pro community there have been several owners who installed aftermarket hard drives already equipped with anti-shock features who reported experiencing Kernel Panic errors whenever their unit was physically moved. This is believed to be due to a confliction between SMS and the new drive's anti-shock function. The Western Digital Scorpio series of notebook hard drives have been the most frequently reported as being susceptible to this problem. In practically all cases, disabling SMS alleviated this problem without any negative performance impact.

Of course, YMMV but I'm in for one and will report back if necessary.
