I have the latest version running and I get this constant error:
TrayStatus Error
Error: One of your Hard Drive counters isn't loaded correctly.
I can't figure this one out.

I have a 64 bit vista

I can report the very same issue. Win7 64bit German. It happened after the latest MS-Updates today after the necessary reboot.
Uninstall, registry cleaning and reinstall v1.2.3 didn't help.

I completely uninstalled it as it became useless to me. I definitely would re install it if you can figure out what happened. I did as the other one did, uninstall, registry clean, hunted everything down. Did a virus and spyware check, did about everything I could do and it didn't work on mine anymore.

IIRC the latest updates were regarding .NET. Maybe that's the issue?

You've got mail

I took a chance and downloaded it again after the last batch of MS updates last week. I got the flash error message, but was able to get in to the options section and removed the check by the show drive activity and then rebooted and it works fine. I had it checked earlier and things went bad. I am leaving that alone.

I am guessing that maybe something with a conflict when the show drive activity is activated may have caused my problem. Could be the ususal culprit... antivirus.

I couldn't get the systeminfo to you via my attempts....seems my computer won't find that file

It didn't work here. I uninstalled and reinstalled as requested but the error still remains. I even unsinstalled .net 3.5.1 (listed as Windows component), then uninstalled .net 4 again and reinstalled all. Same error.
Any other ideas?

There was another .net 4 update from Microsoft today but the problem is still the same.

It worked like a charm on my system with 1.2.2 - until the mentioned MS updates. Then 1.2.2 as well as 1.2.3 always came up with the mentioned error message, only for the harddrives. Caps-Lock and Num-Lock status are still working.

After some MS-Updates (.net4 included) I tried again today. I uninstalled .net3 and .net4, then reinstalled 3, reboot, reinstalled 4 via update function with several necessary reboots. The error still persists.
Any other ideas?

I tried that, too. I also removed all traces from the registry. Result was always the same.
Thank you for trying to solve the issue, but I think I'll give up for now.

Just wondering if anyone ever got this fixed. I just bought a laptop that doesn't have a NUM LOCK indicator, so I tried TrayStatus and for about 4 weeks, it was working great. Now, I basically can't use it. Keeps coming up with a Hard Drive Read Performance Counter Error and a Hard Drive Write Counter Error.

I'm not sure what I did to fix this, but I believe it had something to do with the latest Windows update. I ended up having to do a system recover because the PC kept hanging/freezing, so i rolled back to a prior date. Then I updated Windows again and all is working as it should. Sorry for the delay. DC.

Same issue on Win8.0 Standard in Acer V5-573 laptop. Your workaround of turning off hard drive notifications in TrayStatus 1.2.3 worked.

HOWEVER, due to the way Win8 displays error messages in the Tray, it completely covers the context menu for TS. I literally had to guess using the up and down arrow keys, and I exited the programme several times before FINALLY opening TrayStatus Settings. Then of course it was easy to turn off HDD status.

I do not know what you can do about this, but I thought I should let you know, Mr Lammers.

One easy workaround -- set default to NOT include HDD activity. My Acer lacks an activity light and I would definitely want to see it, but better to have the caps/num/scroll lock features than nothing at all!

I followed up on your PerfMon suggestion. There does seem to be a deep Windows issue going on here. My PerfMon had a warning popup on first use saying counters for Memory, PhysicalDisk and Network Interface could not be loaded. I used an elevated cmd prompt to send a "lodctr /r" command to rewrite the counter database, but it failed (Windows Event 3006). Other sources on the web suggest the need to change registry keys and reload files from the setup disk. The best explanation is from Microsoft itself, but is written for Windows XP:

I have no idea if this applies to Win7, nor less Win8. Perhaps you are skilled and patient enough to give it a go and then recommend this procedure?

I did find an HDD software indicator that works. It is called DriveGLEAM. http://www.dirtcellar.net/software/drivegleam/drivegleam.php
You may want to have a look in for inspiration.
