Mar 15, 2018 If you need to work with Mac-formatted drives on a regular basis and you want the operating system integration, speed, and write access, Paragon HFS+ is a great choice and will be worth it for you. But, if you just need to get some files off a Mac-formatted drive occasionally, this is overkill and you can save $20 by sticking with HFSExplorer. May 31, 2018 This article will walk you through how to check SMART status on hard disks in Mac OS, and it works with both SSD and HDD volumes. Checking SMART status of a drive can give you actionable information about whether a disk is about to fail and therefore is in need of an urgent data backup and drive replacement.

Click the link above to open the script in Script Editor, save, and enter the following line into your crontab: osascript [path/to/file] where path/to/file is, obviously, the POSIX path to the Applescript.
One mistake--make sure you place the POSIX path to the script in quotation marks: osascript '/path/to/file'. Sorry about that

[Corrected the script to ask Finder to display the dialog if there is an error--osascript can't display dialogs directly. Rob, if you want, delete the previous two comments and move this up. Sorry about that.]
This version should discover your drives.
I just made a geektool entry of 'diskutil info disk0 | grep Verified > /dev/null'
Then I set the default icons and turned on icon display. If disk status is 'Verified' then I get a green icon, if it's not I get red.
I edited the script as I wanted to have a DAILY HARD DRIVE VERIFIED STATUS message window displayed, not just when the 'Drive Failed'.

This is a very simply program for a newbie or advanced user - nice GUI. http://www.macupdate.com/info.php/id/7486 Regards Brent --- 'You alone define your limitations'
QUESTION: 10.3: Get hard disk SMART status from the command line
Question: Is the SMART status verified a) when the diskutil utility is run, b) only at boot-up, or c) once every xx hrs?
Does anybody know the answer? For some reason I have it in my head that the SMART status is checked maybe only at boot-up, status is stored somewhere, and then diskutil simply retrieves the status from that 'somewhere'. Am I wrong?
heres a script you can launch on cron and it'll notify you when the result comes back bad: you need to replace [email protected] with the email address you want the alert sent to.
The grep process is unnecessary in returning the status, as awk has its own pattern matching. Also, to get better output, you should print both the third and fourth fields, to handle 'Not Supported' or other multi-word output:
This script should test all your attached drives.
10.3: Get hard disk SMART status from the command line
This command makes a horrible drive parking noise on an intel MBP running 10.5.6. Anyone else experience this or know another method, or the cause of this noise?
Macs arenât immune from hard disk corruption and failures. Theyâre just as common on Macs as they are PCs. Although most Macs have solid-state drives, even these systems can have problems. Appleâs built-in utilities and some third-party programs will get you up and running.
Symptoms of a Hard Disk Problem
The worst noise youâll hear from a mechanical hard disk is a clicking or grinding noise. That means the drive is failing. At that point, the drive isnât repairable. Itâs time to back up your data and then replace the drive. You already have a backup though, right?
Not all drives exhibit symptoms in this way. Sometimes youâll get the prohibitory no symbol at startup or a flashing folder with a question mark. After turning off your Mac and turning it back on, the system boots just fine. Other times youâll get the spinning rainbow wheel, letting you know your Mac is waiting on something. That could be because your Mac is waiting on the hard drive.no symbol at startup or a flashing folder with a question mark.

That could be because your Mac is waiting on the hard drive.
Diagnosing the Problem
If you suspect your hard disk is failing, it is time to make a backup. Now. Again, you should already have a backup of your Mac. Donât proceed before you try to make a backup. Appleâs

Some Macs have a built-in hardware diagnostic. Reboot your Mac holding down the D key. That runs a full hardware test on your Mac. The diagnostic will report any problems, including the hard drive.

Youâll need to boot your Mac off a Disk Warrior flash drive to do testing and repair. The program creates a Recovery flash drive. During its diagnostic process it will repair and optimize the drive. If it detects a hard drive error, the program warns you.

If youâve tried all this and are still having problems, there could be something wrong with your Mac other than the hard drive. If you have a MacBook Pro, the ribbon cable that connects the hard drive to the rest of the computer can go bad. The Mac exhibits all the same symptoms as a failed hard drive. The best way to figure this out is to remove your hard drive and try it in another Mac. If the hard drive works on another computer, then it isnât your hard drive.
Check to see if the repair is free: Check your serial number with Apple. Your Mac may still be under warranty.

The other typical problem is operating system errors. A system update or upgrade was interrupted leaving your Mac in a confused state. You can reinstall your operating system from the recovery mode. That wonât erase any data on your Mac.
Rarely the problem is in the Macâs System Management Controller (SMC) . Before you give up hope, try Appleâs procedure for resetting the SMC.
What if You Have a Solid State Drive?
Solid State Drives (SSDs) donât make the typical noises of a mechanical hard drive. After all,they have no moving parts. The testing procedures are the same. You wonât be able to easily remove the hard drive to test it in another machine. Programs like Disk Warrior are smart enough to change the optimization procedure for an SSD drive.
Some Macs have easy hard drives to replace. Some Mac models hard drives arenât replaceable by end users. Most Mac-savvy retailers know the difference and can guide you towards the right repair. Replacing your hard drive with an SSD will give you the best performance, but may limit your storage space. We cover the differences here.
