It is a hard disk by default but read and write operations reveal different bars on this icon: a light blue bar reflects how the read usage increases and an orange bar reflects the write usage of the disk.
Moving the mouse over the icon displays statistics (total read/written data and current read/write speed)
This feature can be used to determine if a disk is highly used (for example, in a server) or to verify drive performance when moving files between different hard disks.
If this function is not required and you want to disable this feature, please do the following:
- right click on the tray icon and select "Configuration"
- in the window, please select "Hard Disk Drives" page (it is the default)
- uncheck "Display total disk usage on a single tray icon" option (last one)
After pressing "OK", the icon will disappear.
Please let me know any ideas or thoughts about this feature.
