Is there anyway to show % usage of the hard drive?

Hello. Is there anyway to show the % usage of the hard drive (for read and/or write), somewhat like the "CPU Usage" indicator? Thank you.

I might have found the answer myself ... I have tried to created a custom performance counter indicator, by picking "PhysicalDisk" under Category, "% Disk Time" under Counter, and "_Total" under Instance. I suppose the "Threshold" refers to the Maximum value the counter could get.

Hello again ... I have tried to run a few tests using the "Task Management - disk(%)" as my benchmark. It seems the "% Disk Time" Counter may not be what I want. I have tried a couple of different Counter. Not sure which one I should use. And then, I notice under Category, there is "Logicaldrive" besides "Physicaldrive". Not sure which one I should pick. Any suggestion is appreciated. Thank you!

Hello,

The physical disk counter will monitor the HDD itself, whereas the logical disk counter will monitor the volume on the disk.

I don't believe there's a % read/write counter, but if you enable the "Show Hard Drive Activity" indicator, it will display read/write values in MB/s when you hover over it.

Hope that helps!

Thank you for your reply. I am hoping to find a way to quickly tell how busy my harddisk is. Say, if there is a multi-thread program writing 10kb of data to the disk one thread after another, I may see the "write" activity, from the "Show Hard Drive Activity" indicator, happening consistently but it doesn't mean the running apps should slow down, or I should stop running more apps because, considering the small amount of data being transferred, my disk should have enough capacity to handle more I/O. Regarding your suggestion, I agree that I can hover my mouse on top of the icon to see the data transfer rate, which will give me a sense of how busy my disk can be. However, the display is static. In real life, processes may come and go transferring data large and small consistently. If there can be an indicator, like the "CPU Usage", to describe the "Disk busyness" in real-time, I may be able to tell how busy my harddisk is right away. This may help me identify if a particular program is contributing to the disk's I/O limit, or I should close down some apps to reduce the potential disk contention. Right now, I am checking the Windows' Task Manager > Performance > Disk (%) to sort this out. I hope your development team may consider to explore such an indicator in a future release. Thank you for your feedback and consideration. Cheers.
