Something is not right there. First, I doubt that the WHS software would be the cause of any HP voltage reading problems. Second, the current WHS versions are 6.0.1800.0 for all except the Drive Extender which (as of today) is at 6.0.1800.8. (You can see these in Settings-->Resources.) If you are not at least at that level, you should be. To update open the "General" section of the settings and click on "Update Now...". (I recommend you have the Windows Update set to "on" to get automatic WHS updates.)

Now, there is HP software in the MSS as well. You can check the version of that by going to the MSS remote desktop and then into My Computer. Go to the HP MediaSmart Server module, select it (single click) and open the "support information" link. The current version is, I believe, 1.3.6.21622. To update this LOG OFF the RDP session and open the console. Select the MediaSmart Server tab and, in the upper left, under the "HP MediaSmart Server Updates" section, click on "check for updates". You will be updated to the current version. (If not, restart the server and try again.) Again, I recommend you configure automatic updates for the HP software as well.

Which brings up the real problem you are having, the voltage readings. I've got to say I have never heard of the software versions, HP or MS WHS, causign problems with the voltage readings. I ass-u-me you have restarted the unit and still see the same errors (if not, please do so). If the updates solve your problem please post back here and let us know. If they do not, please post back here and let us know that, too. And then I would suggest a new thread to address the voltage problem(s). I don't recall seeing many posts about voltage problems but if they continue I would search on "volt" here and on http://www.mediasmartserver.net/forums to see what problems others have been having. I suspect you are due for a swap of your frame under warranty.
