Also it measures the disk transfer speed in real time which can be used as a benchmark or to detect possible hard disk failures, performance degradations. (Self-Monitoring, Analysis and Reporting Technology) values for all hard disks. Hard Disk Sentinel monitors hard disk drive / HDD status including health, temperature and all S.M.A.R.T. See the How to: monitor Network Attached Storage (NAS) status for information about hard disk monitoring in Network Attached Storage (NAS) devices. information about LTO tape drives and appropriate industrial (micro) SD cards and eMMC devices too. In addition Hard Disk Sentinel Pro detects and displays status and S.M.A.R.T. SSDs, hybrid disk drives (SSHD), disks in RAID arrays and Network Attached Storage (NAS) drives as these are all included in a single software. No need to use separate tools to verify internal hard disks, external hard disks, Many different alerts and report options are available to ensure maximum safety of your valuable data. Hard Disk Sentinel gives complete textual description, tips and displays/reports the most comprehensive information about the hard disks and solid state disks inside the computer and in external enclosures ( USB hard disks / e-SATA hard disks). Its goal is to find, test, diagnose and repair hard disk drive problems, report and display SSD and HDD health, performance degradations and failures. Sudo rm -r /Library/Extensions/SATSMARTLib.Hard Disk Sentinel (HDSentinel) is a multi-OS SSD and HDD monitoring and analysis software. Sudo rm -r /Library/Extensions/SATSMARTDriver.kext Open the Terminal App, type following commands: Majority of USB-C enclosures such as YOURS, are based on NVMe technology, for which there is no ISO/ANSI standard driver support to query SMART status for NVMe/M.2 over USB. SAT SMART Driver is external 3rd party project and it is not officially supported by BinaryFruit”Īdditional this driver is for USB-A/Firewire drives ONLY, as clearly indicated on the download/install page. “SAT SMART Driver project is not a part of DriveDx project 1.1 back in 2013 and it’s never killed any drive, made unreadable, on any system, HDD or SSD, especially a non-booting EXT drive.ĭriveDx doesn’t write anything to EXT drives, change headers, modify hardware settings/registers, etc. We have been using it in our computer consulting/service business since Ver. No offense, but it’s highly unlikely that DriveDx killed your SSD. A backup offers a way to restore that data, and you’ll be grateful to have if you ever need it.ĭo you use DriveDX to check on the health of your Mac SSD or disk drives? Do you use another tool or method to keep an eye on drive health? Share your experiences and thoughts in the comments. If the drive completely fails and you don’t have a backup, you’re out of luck and all your important data is likely gone for good. Drives do fail, and sometimes spontaneously. Regardless of how your SSD is rated in DriveDX, it’s always a good idea to backup your Mac with Time Machine or another backup method. Not too bad for nearly 4 years of continuous use! You can further drill down by choosing the “Health Indicators” option from the left sidebar to reveal other indicators of the drives health, including temperature readings, drive reading and write, power cycles, time on, and more.įortunately the soldered in flash memory drives used on modern Macs have a lengthy lifespan, as demonstrated by the screenshots taken for this article, which show a first gen Retina MacBook Air SSD has only used 4% of it’s estimated lifespan according to the Life Percentage Used indicator. Open DriveDX and you’ll get an overview of the drive, including an overall health rating, SMART status, and lifespan indicator. If you want to continue to use DriveDX past the two week trial, you can pay for it. Get DriveDX from the developer, Binary FruitĭriveDX offers a free trial, allowing you to see the current health status of your SSD.By checking the health status of your SSD, you can potentially get ahead of issues, back up your data, and at least consider your repair options absent a disastrous scenario. Knowing the health of your disk is important for many reasons, but it may be of particular significance now that most modern Macs have SSD drives soldered into the logic board, which means if the SSD is failing, the entire logic board has to get replaced – a much more expensive repair than simply swapping out a drive.
