The first thing you need to do is install Xcode, an Apple app for developers. It has a set of command line tools that your Mac needs before you can install and run Homebrew, which is a prerequisite for running smartmontools. You can get Xcode in the App Store for free.
Smart Ssd For Mac
With smartmontools and DriveDX I can successfully get data from a Maxtor HDD and a WD Element HDD, so I think, drivers are good, and the procedure of attaching the external drives after a reboot works.Still can't get SMART data from the Samsung T5.
WHY USE SMART UTILITY?SMART Utility is different from other drive utilities, such as Disk Utility, which only read the overall SMART Status. SMART Utility not only displays the individual attributes to see their status and information, but it also uses an internal algorithm based on those attributes to detect drives failing before SMART indicates it has failed. This pre-fail detection can save precious data before SMART has determined that the drive has failed. And, while the raw information can be viewed on the command line with smartmontools (which is what SMART Utility is based on, SMART Utility presents it in an easy to read format, as well as running its internal pre-fail algorithm. Plus, with the ability to run self tests, problems can be detected even sooner.
The DockCase Smart SSD Enclosure is designed to provide safe, reliable protection for large amounts of data. It features Power Loss Protection (PLP), smart SSD health info detection, and dual-heat dissipation. PLP is built-in to reduce the risk of data loss when a drive is unexpectedly disconnected from power. It uses onboard supercapacitors to sustain power to the SSD long enough for data to be written to Flash memory. The main features of the DockCase enclosure are:
GSmartControl is a graphical user interface for smartctl (from smartmontools package), which is a tool for querying and controlling SMART (Self-Monitoring, Analysis, and Reporting Technology) data on modern hard disk and solid-state drives. It allows you to inspect the drive's SMART data to determine its health, as well as run various tests on it.
To follow up on last week's article on Mac SSD deterioration, I decided to see for myself what was happening on my machine. With the aid of a post from Macworld's Roman Loyola I loaded smartmontools.
TL:DR version of the process: load Xcode (Apple's IDE); then Homebrew (a popular package manager); and then smartmontools which reads the SMART (Self-Monitoring, Analysis, and Reporting Technology) built into most drive controllers for the last 15 years. Xcode is 12GB, so it takes a while. (Update: Alert reader Jdanek pointed out that savvy users can simply download 430MB of Command Line Tools, saving time and drive space.)
I checked smartmontools wiki to find instructions about its usage with USB hard drives and found out you have to add -d with the correct driver, in my case it's -d sat. Unfortunately the output of the correct command on macOS Mojave is:
Due to OS-specific issues and also depending on the different state of smartmontools development on the platforms, device support is not the same for all OS platforms.See info about RAID-controller, USB and NVMe support here on the homepage and of course in the manpages.

For those who would prefer to run the Terminal command themselves, it takes the form/usr/local/sbin/smartctl -A /dev/disk0where you should substitute disk1, disk2, etc., for respective drives, as necessary.
Compare that with the figure from indicator 175 Host_Writes_MiB, which you should divide by one million to arrive at the value in TB. Currently my figure shown in smartctl is 6333234, which becomes 6.3 TB. So my iMac has currently used about 1% of its expected total writes over the six months it has been in use. Assuming a similar write rate, its SSD should therefore be good for a total of around 100 x 6 months = 50 years.
I found that smartmontools can be installed via Homebrew. Among other things, this means that you can run the smartctl command, in the terminal, without the file path in front. I also presume that, if this software is being actively maintained, updates will take care of themselves.
Just a quick note to let you know that when smartmontools are installed via brew, the path to the executable is `/usr/local/bin/smartctl` and not `/usr/local/sbin/smartctl`I manually changed the .scptd script to make it work. To make the .app work, I had to drill down into the main.scpt file inside Resources->Scripts and change it there. Hope that helps someone else. 2ff7e9595c
