![]() “Self-test” means that drive performs self-diagnostic routines (usually by user request). In this case you could submit an issue to developer. Even if drive enclosure is SAT capable, current version of SAT SMART Driver may not support it.You can find list of devices that supports SAT technology here. Check if your external drive enclosure controller is SAT (SCSI ATA Translation) capable.Uninstall current driver, download SAT SMART Driver v0.10 Install it. Try to install another version of driver.macOS does not allow multiple drivers for the drive at the same time, so if you installed any drive vendor-specific driver – uninstall it (for example Samsung driver for Samsung Portable T5 SSD).Try to rebuild/refresh system kernel extension cache (can be especially helpful after any macOS upgrades).(For Mac’s with T2 chip) Physically reconnect all your external USB/FireWire drives again.Reboot your computer after driver installation.Physically reconnect all your external USB/FireWire drives.data from external drives), but Apple Disk Utility still reports “SMART Status: not supported” for the specific external drive(s) you are using: Troubleshooting tips if you installed the SAT SMART Driver (special driver to allow your Mac to receive S.M.A.R.T. The more measurement history DriveDx has – the more precise its results. For such health indicators, DriveDx uses heuristics based on measurement history for the detection of a possible range of min/max values. This is especially could be important in case if the drive has some undocumented proprietary (vendor-specific) health indicators (S.M.A.R.T. The more measurement data (history) DriveDx has, the more accurate the results. The last one (measurements history) also could be a cause of different results on multiple computers for the same drive. health indicators (SMART attributes) proximity to threshold.SMART attributes statistically closely related to HDD or SSD failures.For example, some Intel SSDs could report some strange results when its firmware performs garbage collection routines.ġ) Some subset of HDD / SSD health indicators is related not only with HDD / SSD itself but also with hardware environment (computer, ports, cables, power supply, drive and ambient temperature and (sometimes even) electrical noise).Ģ) DriveDx evaluates drive health status based on the next criteria: ![]() SSD results could be affected by internal firmware activities related to garbage collection and self-recovery routines. ![]() High temperatures could trigger thermal throttling and affect the performance of SSDs.
