Standalone Utility: Retrieving Information

Sometimes it is useful to retrieve internal technical data about computer, operating system, or application version in single user mode. This is possible by using the menus Show Computer Information and About TinkerTool System Standalone Utility.

Hardware Information

Hardware data about computer, processor, and memory equipment can be displayed as follows:

  1. In the main menu, type 5 to choose Show Computer Information.
  2. Type 1 to call the function Show Hardware Information.

The following example shows an overview of the information which can be retrieved:

This corresponds with a simplified version of the feature Info > System Information in TinkerTool System.

Operating System Information

Information about operating system, system kernel, and operation mode can be retrieved as follows:

  1. In the main menu, type 5 to choose Show Computer Information.
  2. Type 2 to call the function Show Operating System Information.

An example is shown here:

Operating System Information

                    Version: macOS Version 10.12 (Build 16A322)
            Base OS Version: Darwin 16.0.0
                     Kernel: Darwin Kernel Version 16.0.0: Mon Aug 29 17:56:20

S.M.A.R.T. Status of Hard Drives

All modern hard drives use a diagnostics technique complying with an industry standard which is called S.M.A.R.T. (Self Monitoring, Analysis, and Reporting Technology). This standard has been introduced in 1992 to react earlier on hard disk failures. A hard drive supporting the S.M.A.R.T. standard monitors itself with its own micro processor and allows the operating system to request readouts that indicate whether operational parameters have changed in such a way that the hard disk might become defective in the near future. In this case, the hard disk can be replaced before any data is lost. The diagnostic processor of the hard drive summarizes the internal readouts into a simple yes/no value, the so-called S.M.A.R.T. Status. It can have the following two values:

Note that the S.M.A.R.T. Status does not indicate whether the drive is currently OK, or has a defect. It is not a test result in the strict sense. The S.M.A.R.T. Status is a recommendation only which assesses how the hard drive might behave in the near future. This assessment is based on the monitored technical data and the experience of the respective hard drive manufacturer.

Use the following steps to show the S.M.A.R.T. Status values of the attached hard drives:

  1. In the main menu, type 5 to choose Show Computer Information.
  2. Type 3 to call the function Show S.M.A.R.T. Status of Hard Drives.

A typical result looks as follows:

S.M.A.R.T. Status of Hard Drives

---------------------------------------------------
Disk Drive            Serial Number   Status
---------------------------------------------------
SAMSUNG HD250HJ       S0URJ9DPC12345  Verified
WDC WD6400AAKS-41H2B0 WD-WMASY6712345 Verified
SAMSUNG HD252KJ       S0NJJ9BQF54321  Verified
---------------------------------------------------

Most external hard drives are connected via a bridge chip which “translates” all transferred data between the SATA standard and the standard of the connection being used (e.g. USB or FireWire). Due to technical limitations, these bridge chips are not capable of transferring S.M.A.R.T. data. For this reason, the S.M.A.R.T. Status of hard disks can only be retrieved from drives which are directly connected to the computer by a SATA bus.

Version Information of the Standalone Tool

The version number of the standalone utility and legal notes can be displayed as follows:

  1. In the main menu, type 6 to choose About TinkerTool System Standalone Utility.
