From what I understand, cidaemon.exe is used to index the files on your computer for faster reading. If one of the files is corrupt, windows gets stuck in a loop trying to read it. To fix it:

1. Right click on any drives that are using NTFS, then select properties.

2. Make sure that 'Allow Indexing Service to index this disk for fast file searching' is turned off.

If anyone else knows of a better way to fix this, please post your suggestions.

You should be able to turn off and disable the Indexing service by opening the Services console (either go through the Control Panel / Administrative Tools, or do Start->Run->"services.msc"), find the "Indexing service", stop it and set the startup type to Manual.

And that ought to do it. Alternatively you can open "My Computer", right-click on each of your drives and pick Properties, and uncheck "Allow Indexing Service to index this disk for fast file searching". If all of your drives have that unchecked, then cidaemon *might* stop bothering you. Disabling the Indexing service would probably work better though.

Note that if you do a lot of searching for files, you might want to leave the Indexing service on. Or figure out a way to arrange your stuff such that you'll be able to easily find anything you need.
