Windows Forum / Windows XP / 64-bit / April 2008Diskmon in Vista?
Has anybody tested Diskmon (http://technet.microsoft.com/en-au/sysinternals/bb896646.aspx) in Windows Vista? "DiskMon is an application that logs and displays all hard disk activity on a Windows system. You can also minimize DiskMon to your system tray where it acts as a disk light, presenting a green icon when there is disk-read activity and a red icon when there is disk-write activity." Carlos The jury is still 'out' pondering the warranty ramifications for my 64bit dual-core, so out of boredom I installed this to my Win2K machine. I have to say that the 80K's of code is probably a lot more interesting than the utility itself. One interesting observation might be that the icon seems to log much more activity than the front-panel LED is doing!

My newest laptop (HP530) has Vista Home Premium 32-bit and doesn't have any LED for HDD activity. That, and the fact that the hard disk is quite silent, leads me to a blind/deaf state for monitoring disk activity. After googling a little, I found DiskMon and installed it on Windows XP at work, w/o the permission of the IT guys!!! I noticed the same as you, there's a lot of activity monitored by DiskMon that doesn't show up in the front cabinet LED. It seems as if small read/write operations don't have the time length required for the human eye to see them, but DiskMon systray LED must surely be extending that time artificially so that it is visible to the eye. The WinXP version requires no driver at all and it is just that, an executable. Which leads me to think that it should work in Vista x86. Don't know whether this line of thought also applies to Vista x64. Maybe someone jumps in and sheds some light.

That I find surprising, but at the same time I'm not really surprised - I didn't put all laptops to that much scrutiny so I can have missed any number. For that kind of application I agree, that makes it potentially usefull. I don't think I would bother to set it up to autostart, though. With 80K's of binary instruction, it has got to be well written - and I would expect nothing else from MR. According to his notes, the tool is written as a GUI/Devicedriver combo, using a substitution technique by intercepting the device's own driver and subverting information that it can use to be displayed for it's own purposes. Since Devicedrivers on Vista are written on a completely new foundation, as I understand it, your hopes may not be realized? Let's see what people have to say.

Systray "LED" always glows red, as apposed to XP where it blinks green for "read" and red for "write". So far so good, real LED's on cabinets do not change color when reading or writing to HD.

It's got a blue array of Power, Disk and Charge/Plug-in status. So, it clearly picks up a signal in 32bits, let's keep hoping, but I do suspect the 'Red Only' may in fact indicate a Vista peculiarity, since the LED wouldn't ever be static, or you cannot monitor any activity!

The disk activity light on the hard drive is at the opposite end; the bottom of the storage stack. In between you have layers of caching. Diskmon is reqorting disk activity (the blinking light) which is satisfied from cache and doesn't actually make it to the disk (no blinking light). > Hi Tony, > Here's the whole story, as I was in a hurry when I posted my question this [quoted text clipped - 41 lines] >> > activity and a red icon when there is disk-write activity." >> > Carlos Thanks, John!
