Journal of a guy who loves Excel

Not only about Excel, but also daily stuff to kill my boredom.

What the xxxx is crcdisk.sys and what it means when it's not booting: Windows Server 2008

Hello guys, now a days I haven't used Excel very much instead of that I have been playing with Windows server. Yesterday when I was just leaving, it happened suddenly... There was an instant of darkness because of the power cut and all the machines at office were OFF! As a simple data storage for BO members and an SQL service for all of the companies, we have a Windows Server right here just at my feet. Unfortunately, it doesn't have any UPS (an uninterruptible power supply) so it turned off as well as other machines. I was thinking that it must be back at it just pressing the power button but it wasn't. No matter how many times I tired, it was not booting. I also tired booting with using an Install DVD but the result was same. It neither boot Normal nor in one of the various Safe Modes.
I have never felt that I should've installed an UPS no matter how the server is stabled. Yeah...hindsight is 20/20.

Anyway, as a system administrator, there is no other way but turn it back to normal, so I goggled with various search words to find the way to fix this problem.
In the process I tried to turn the server back in Safe Mode, I noticed that every time the command line startup stops at crcdisk.sys, so I decided to use this word for searching and many result were found. But it seemed a categorical cause is not clear, I mean everyone tried various ways and nobody knows exactly what is happening in the inside. So I'm not sure if it works for you but I hope my jottings helps some. FYI, I'm the one who never wanted reinstall whole the system. ;-)

Okay, what I did was as follows.

#1: Plugging the exact same hardware in the exact same sockets where they were attached before shutdown.

#2: Completely removing battery and power supply, waiting 10 minutes. And after reconnecting the power.

#3: Reboot. It showed the same black screen with a progress indicator for a long time, but leave it as it is for all night long. In my case, I could see the log-on screen on the next morning.

Hope this helps.

Masaru aka Colo- one of an ex-Microsoft MVP for Excel


I'm Masaru from Kobe, Japan. I'm a computer system administrator for an equipment manufacturer. My line is operation AS400 server and Windows2008 server. I sometimes write VBA code for the company.

From 2004 to 2009, I had been nominated as a Microsoft Excel MVP, but now days, I have no opportunities using with excel in my daily life, so I decided to quit being an MVP. But I still love to use Excel.
