S.M.A.R.T. status of drive from CLI?

DiskUtility.app gives just one line status report of S.M.A.R.T.
The same info can be obtained by

system_profiler SPParallelATADataType

(or 'system_profiler SPSerialATADataType').

If you want more detailed report, it seems you need a prgram like smartmontools. I have never tried this but their homepage says Darwin(MacOS X) is supported.

PowerMac G4 Mac OS X (10.4.8)

Try

diskutil info /dev/disk0 | grep SMART

If you don't know the device name, diskutil info will give it to you.

I guess it wasn't present in 10.3? It even works (in 10.4) if you just give '/' instead of the device id (I'll omit the 'grep' so you can see it all):
<pre>

ibook:~ michaelc$ diskutil info /

</pre>I originally thought it would need the device name, but you can see it isn't necessary. What other things are missing in 10.3?

Are you sure the drive you are looking at supports S.M.A.R.T. reporting? Not all do.

This doesn't add much, but the SMART stuff is in

%nm /System/Library/PrivateFrameworks/DiskManagement.framework/Versions/Current/Dis kManagement | grep -i smart

FWIW from my machine and the statement below the data is from an email of Marcel Bresnik(Temperature Monitor) in regards to a question I asked him.

doug-pennington-s-Computer:~ pennington$ diskutil info /dev/disk0 | grep SMART
SMART Status: Verified
doug-pennington-s-Computer:~ pennington$ u
doug-pennington-s-Computer:~ pennington$ %nm /System/Library/PrivateFrameworks/DiskManagement.framework/Versions/Current/Dis kManagement | grep -i smart
-bash: %nm: command not found
doug-pennington-s-Computer:~ pennington$ nm /System/Library/PrivateFrameworks/DiskManagement.framework/Versions/Current/Dis kManagement | grep -i smart
90c39a58 t -[DMDisk _getSMARTData:]
90c39964 t -[DMDisk _getSMARTDevice:]
90c3742c t -[DMDisk smartStatus]
90c3671c t -[DMDisk(Mutable) setSmartStatus:]


Most hard drives contain a diagnostic processor which is computing
the S.M.A.R.T. verification status and which is keeping an internal
attribute table with detail status data, including the current
temperature.
You can get this data by sending S.M.A.R.T. requests to the drive.
The way to interpret this data can be different for each drive model.

Cole,

Have you seen this? I stumbled across it this morning.

Sending SCSI or ATA commands to storage devices

here's a paragraph from the above article.

"The same design applies to the ATA family as well: sending commands directly to ATA and Serial ATA (SATA) devices is unsupported. However, the ATA family does provide a device interface that allows applications to read SMART (Self-Monitoring, Analysis, and Reporting Technology) data from ATA and SATA devices that implement the SMART feature set."

Cole--

I read that article and it seemed to imply that ioreg
might be able to read smart attributes. This is what
I've found regarding my hard drive and there are
references to SMART. But I'm unfamilliar with ioreg.
Given the following info, could ioreg dig a little
deeper?

I don't think ioreg will give you much more information than that. Interstingly, on my PowerBook, just one block below the one you posted, is the block storage driver entry, which includes statistics:

<pre class="command">ioreg -w0 -n IOBlockStorageDriver | grep IOBlockStorageDriver -A6</pre>So there's a little bit of useful information there.

But if you really want comprehensive information on your drive's S.M.A.R.T. status, you really want smartmontools. You'll need to have the Xcode tools installed to build it, but I've built and used it with PowerBooks running 10.3 and 10.4. You can even use it to run surface scans on your internal drive.

I was hoping for an out of the box solution that I
could deploy to a couple dozen other macs we have
without having to install xcode on each. Looks like I
can do that for machines running 10.4, though.

Well, if you're trying to deploy across a number of machines, you could try compiling on one machine and copy the binaries across to another machine. The binaries are installed in /usr/local/sbin/ by default, I think.

The only problem I've had with it so far is that it won't work on my 24" iMac with a Western Digital drive, though it works on a G5 iMac with a different WD drive. So your mileage may vary.

Also, in looking around, I found a project called maxwell at Sourceforge. It's similar to smartmontools. It also compiled (with one error) and ran on my PowerBook. It compiles on the Intel iMac, with the same error, but won't read any information from the drive's firmware.
