W7 Resource Monitor shows activity on wrong drive

[mooreg]

The disk activity graphs in Windows 7 resource monitor show what appears to be an identical amount of activity on my system drive (C and also on a drive I use for data storage (I. In the activty pane where it shows file access, it shows ALL the activity as taking place on the second drive (I. None of the files exist on that drive, of course.

Any ideas on what may be going on? Or is this just a bug with the display?

Thanks,
Gerald

Hi mooreg and welcome to Seven Forums.

Could you please post a screen shot off what you are seeing.

It would be really helpful

I think you are confusing 'drive' and 'partition'. Your C and I are probably two partitions on the same physical drive - and those are always shown together. Resource Monitor cannot distinguish between different partitions on the same physical device.

In my picture I have 3 physical drives and 5 partitions ==> C, M and E,Z,L. The last 3 partitions are on the same physical drive.

Just what I thought that's why I wanted a screen shot

Nope. That wasn't from me. The two drives are two physical drives. I'll put up a screen shot later today.

Cheers,
Gerald

Yes could you please post a full screen shot of Disk management also.

 

[mooreg]

Here is what I have. I notice the graphic at the top is actually showing all disks, and not disk I as I originally thought. But why is the activity panel showing the path as disk I when the activity is clearly shown on disk C, which is the OS disk?

The storage panel shows essentially what is in disk management. They're all basic disks.

 

[benjy206]

Partition I: Seems to have a OS on it as you can see the file path "I:\Windows\Sys"

Extend it fully to see the full path

 

[mooreg]

That is why I am so confused. Disk I is a data disk. The OS is on C. All the activity in the graphs is shown on C. There is literally no activity shown on the graphs for disk I. So, either the activity panel is incorrect (which I believe to be true) or else the graphs are incorrect.

 

[benjy206]

Yes very strange.

I know this is stupid, but have you tried a restart on the computer.

Also I would run the sfc /scannow command

 

[mooreg]

It's probably been a while since it rebooted. Usually I only do that when Windows update asks for it.

I'll run SFC at some point this weekend and see what happens.

 

[benjy206]

Ya maybe you should try a reboot on the system to see if it helps and also run the sfc command if that doesn't fix it

 

[logicearth]

The graphs are not incorrect, Resource Monitor is not incorrect. If they were, the whole system would be incorrect, which it might be. What is this "1" folder on the I: drive? That is what is being accessed. In fact it does not look right at all, something is up with your system. "I:1\Windows" is not what would be expected.

 

[mooreg]

Rebooted no change. SFC reports no abnormalities. I noticed in disk management that disk I was set as active. I changed it to inactive with diskpart and that still did not change anything in resource monitor.

Baffled, but as the system seems to be running fine, I am just going to let it go for now.

 

[benjy206]

I'm baffled to very strange.

@logicearth: Very strange, you would normally only see this on the OS partition. Could be something corrupt, or virus.

 

[mooreg]

I'm pretty stumped. Tempted to give MS support a shot at it.

I could be crazy.
Notice the top graph in the posted picture does not have a drive letter. My understanding is that is a total of disk activity not any particular disk. All the other graphs have drive letters where one can see what each individual disk is doing.
Also notice the different Queue Lengths.

 

[mooreg]

Yeah. The top graph shows total activity. The last graph (if I remember right) shows drive C with lots of activity. The activity panel shows all the files as being on a path that does not exist... I:\1\Windows etc). The graph for drive I shows no activity.
