I'm trying to get a detailed SMART status report on the drives in my Mac. I'm not talking about "Verified," I'm talking about the detailed report that's about 100 lines long listing all the vital statistics of the drive.

Anyone know how to do this with diskutil? If diskutil can't do it is there a different free tool I can use?

I recently had the same question and found a command line tool www.smartmontools.org which can be installed via brew:

brew install smartmontools

you can then run it

smartctl -a disk0s3

for the full report where disk0s3 is the disks physical baking which can be found in Disk Utility.app by getting info on the drive. (There must be a way to find this under OS X at the command line.) Here is an example of the output:

smartctl 6.2 2013-07-26 r3841 [x86_64-apple-darwin13.1.0] (local build)

Perfect! I had to use -a instead of -H to get a full report. Not sure if this is because you had a different version of smartctl or a typo. smartctl -a disk0 –  Mike Akers Jun 19 at 22:47
    
Yes, it was suppose to be -a, I have corrected my answer –  Lee Joramo Jun 19 at 23:00
