Mac OS Terminal

No need to install anything, but you will only get a “verified” status, not the whole HDD SMART attributes list.

To find about the drives and their numbers/ID, type this in the terminal:
diskutil list

To get the report on a particular drive (disk0 for that instance):
diskutil info disk0 | grep SMART

mac os terminal smart status

MHDD Free Software and Hard Drive Diagnostic Tool:

You can type SMART ATT command or press F8 to get SMART attributes. What do they mean?

The most important thing is the raw value of «Reallocated Sectors Count» attribute, which says how many remaps are on the drive. Normally, you should always have zero there. If it is more than 50 — you have a problem. That means you have bad power supply, vibration, overheating or just broken hard disk drive.

Take a look at the temperature. The best values are between 20 and 40 degrees centigrade, but some drives do not report their temperature.

UDMA CRC error rate attribute means how many errors have happened during transferring data through IDE/SATA cable. You should normally have zero there. If it is not zero, you have to change your cable immediately. Also overclocking may result in increased error rate.
