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:

Hardware Information

         Apple Model Code: MacPro4,1
            Serial Number: CK912345678
              System UUID: 12345678-ABCD-1234-ABCD-1234567890
       Week of Production: Week of 2009-02-23

           Processor Type: Intel(R) Xeon(R) CPU E5520  @ 2.27GHz (Family 6 Model 26 Stepping 5)
Number of Processor Units: 8 (16 logical, 16 active)
  Nominal Clock Frequency: 2260000000 Hz
      Bus Clock Frequency: 5866000000 Hz
      Level 1 Cache Sizes: 32768 bytes data, 32768 bytes instructions
        Other Cache Sizes: 262144 bytes level 2, 8388608 bytes level 3

         Main Memory Size: 6442450944 bytes

                 Firmware: MP41.88Z.0081.B07.0910130729 (10/13/09)

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: Version 10.6.4 (Build 10F569)
          Kernel: Darwin Kernel Version 10.4.0: Fri Apr 23 18:28:53 PDT 2010;

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 ATA 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 via an ATA 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.
