SMART status of disk on MAC OS X

Launch Disk Utility, pick Disk you want to check from Left Side Bar and Hit Verify Disk on First Aid Tab. If everything turns out good you should see the message:

The volume … appears to be OK

For checking the same on command line, get list of disks with command: diskutil list

and then get information on the disk with command: diskutil info disk0

SMART status Verified means HDD reports it’s doing just fine. No need to worry today
