The power on time is usually indicated in hours, but some manufacturers show this time in minutes or even seconds.īy pressing the Start button the whole surface of the disk will be scanned for defects. Status: status of the parameter (OK or failed). Data: shows the usable data which belongs to the ID. Threshold: the value of any of the parameters should never get below the threshold. Worst: the worst value which has been recorded since the hard disk was first used The table shows the following parameters: (Self-Monitoring Analysis and Reporting Technology) to get information about the health of the hard disk. Maximum transfer mode and active transfer mode (The capacity between braces shows the capacity as it is marketed by the manufacturer defining 1 KB as 1000 bytes) The second part shows which features are supported. The first part of the screen shows detailed information about each partition on the hard disk. The CPU usage shows how much CPU time (in %) the system needs to read data from the hard disk. The burst rate is the highest speed (in megabytes per second) at which data can be transferred from the drive interface (IDE or SCSI for example) to the operating system. The measured access times are shown on the graph as the yellow dots. The average access time is measured and displayed in milli-seconds (ms). In the options screen (press the button) you can select the test duration. Some benchmarks define one megabyte as 1000000 bytes which results in higher scores. *note*: One megabyte equals to 1048576 bytes (=1024 kilobytes). The blue line on the graph shows the read performance across the disk. The minimum, maximum and average speed are displayed on the right. The read speed is measured in megabytes per second (MB/sec).

HD Tune may also work with other storage devices such as memory cards, USB sticks, iPods, etc. Error Scan: scans the surface for errors.Health: checks the health status by using SMART.HD Tune is a Hard Disk utility which has the following functions:
