The hIOmon "Raw Device Extended Feature Option" enables you to collect the "Physical Device Extended Metrics", which basically reflect disk I/O operation activity at the "physical volume" or "physical device" levels within the Windows OS I/O stack for those disks that are partitioned/formatted (e.g., have a filesystem upon them).

Moreover, these metrics automatically correlate file I/O operations with their associated physical volume and/or physical device I/O operations. That is, they essentially reflect those physical volume/device I/O operations that were performed so as to satisfy file I/O operations which were also monitored by the hIOmon I/O Monitor at the associated file level (i.e., they basically reflect “physical volume/device” I/O operations that were required to complete file I/O operations for those files that were also being monitored by the hIOmon I/O Monitor).

Values present within the various hIOmon "PhyDev" metric types indicate that the hIOmon software was successfully configured to include the collection of the "Physical Device Extended Metrics".

The various hIOmon "automated configuration scripts" (such as the hIOmon "Device and File I/O Performance Analysis Add-On" configuration script) provide the option to enable the collection of the "Physical Device Extended Metrics".

So looking at your hIOmon export files and hIOmon Presentation Client screenshots, it appears that you have been successfully collecting these metrics (presumably based upon your use of the various hIOmon "Add-On" configuration scripts).
