    I installed the 10.7 developer's preview on my 2010 13" MBP. I heard that if you go into disk utility, click on the drive, and then click the i for info, it will give you all the SMART data. So I did that. I don't know how to read the SMART data, though. Maybe someone can help me? I have uploaded the screenshots, to better assist someone in reading the data.... Thanks again, forum (that is how I should refer to you, right?)!

    The SMART data is written in code. The attribute that I am specifically looking for is the Load/Unload cycle count. It is written as 2C1D. I googled 2C1D load cycle, and apparently 2C1D is an abbreviation for a pornographic film, so that was a very unhelpful search...

    I would take your MBP to the Apple store because they usually are nice and can fix the issue that you have.

    I don't have an "issue." I just need help reading the SMART data. The "Geniuses" at the Apple store do not know how to do this sort of thing, and I thought that the forum might. Also, there is no support for 10.7 right now. They may even void my warranty when they hear about 10.7... I have heard about them voiding a PowerBook warranty because the owner of the PowerBook had a sticker from some sort of fruit on it.

    I need to know the load/unload cycle count because my drive has been clicking lately. It doesn't seem like the "click of death," but I am worried that my not using HDAPM for a period of time has ruined the drive.

    Sorry to unbury an old thread but I have an answer for future Googlers.

    That value is a hexadecimal number. http://easycalculation.com/hex-converter.php can convert that to base-10 for you. In your case, the cycle cout is 11293, well below the usual lifespan of a hard drive.
