Seek Time - Disk Wait Times for Read and Write

Hi Guys.

Firstly this is a great tool for a quick snapshot of how a SQL Server is doing.

I would like to know how this tool is getting is values for Seek Time - Disk Wait Times for Read and Write.

I have setup Performance Monitor to capture values on Avg Disk Sec/Read and Avg Disk Sec/Write for both Logical Disk and Physical Disk but the values are very different.

I have setup a trace and see what this tool fires at the SQL Server but there is nothing in there for these counters.

Please help!

Thanks.
