I’ve added an IPv6 address for the website, so if you have an IPv6 connection you will be able to connect that way. Since Apple is pushing towards more use of IPv6, and as more users adopt IPv6, it only makes sense to support it. Let us know if you have any issues!Continue reading
The easy to use, hard drive diagnostic software.
WHAT IS SMART UTILITY?
SMART Utility is an application to scan the hardware diagnostics system of hard drives. SMART (Self-Monitoring, Analysis, and Reporting Technology) is a system built into hard drives by their manufacturers to report on various measurements(called attributes) of a hard drive’s operation. The attributes can be used to detect when a hard drive is having mechanical or electrical problems, and can indicate when the hard drive is failing. SMART Utility can read and display these attributes. This allows time to hopefully backup, and then replace the drive. SMART Utility also allows running a drive’s built in self test, which can also indicate malfunctions on the drive.
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.
Displays all supported internal drives and their partitions, as well as some external drives (if optional SAT SMART driver is installed)
Displays important information in the main window, such as drive model, capacity, power on hours, temperature, bad sector counts, and error counts and types
Displays easy to read overall SMART status with color coded text
Displays more detailed information in separate windows, including capabilities, all available attributes, and the past five errors
Displays information using the Growl notification service (if installed) and email notifications (if configured)
Displays information in menu bar
Supports scanning in the background
Supports running a hard drive’s built-in test, and displays the results of the test
Supports scanning OS X software RAID drives, as well as drives in many RAID enclosures and cards (including SeriTek drives)
Supports logging all information to a log file for verifying SMART data
Supports customizing the pre-fail algorithm, including only alerting new bad sectors and error counts
Supports saving drive reports for later viewing
Supports printing drive reports
Supports HDDs and SSDs
Supports Mac OS X 10.9 through 10.11

Note: SMART Utility is based on the command line “smartmontools”, an open source software package that does the actual scanning of SMART attributes. SMART Utility only parses the data that smartmontools outputs, and it would not exist without it. It is available on their site.
