![]() ![]() On other machines it might not be possible to locate the SMBus on these machines to collect the RAM's SPD data. PassMark DiskCheckup™ allows the user to monitor the SMART attributes of a particular hard disk drive.(The SMBus is the low speed circuit on the motherboard that connections the CPU to various other components on the motherboard and it is used to transfer the PSD data from a RAM stick to the CPU). SMART (Self-Monitoring Analysis and Reporting Technology) is a feature on a computer's hard disk for providing various monitoring indicators of disk reliability. If SMART is enabled on a hard disk, the system administrator can receive analytical information from the hard drive to determine a possible future failure of the hard drive. SMART monitors elements of possible long term drive failure, such as 'Spin Up Time', the number of start/stops, the number of hours powered on and the hard disk temperature.ĭiskCheckup displays the current values of the SMART attributes, along with the Threshold value for that attribute. If an attribute drops below its threshold, the drive cannot guarantee that it will be able to meet its specifications in the future. Note that SMART attributes change slowly over time and are helpful attempts to diagnose the life span of a particular drive. DiskCheckup monitors these changes over a long period and predict the date (if available) of the Threshold Exceed Condition (TEC), which is displayed on the main window.ĭiskCheckup can also execute built-in Disk Self-Test (DST) routines implemented by the vendor to detect drive failures. ![]() There are two main self-test routines: Short Test and Extended Test. The results of these tests are displayed in DiskCheckup.ĭiskCheckup can detect and set the sizes of the Host Protected Area (HPA) and Device Configuration Overlay (DCO). ![]()
