this actually came up after an infection of system on clean install the infection was Windows Police Pro
While attempting to boot in safe mode, the system was hanging at "crcdisk.sys". I was able to fixed it this way: I ran Start-up Repair on the boot disc, and it actually did work, whereas the boot disc wasn't able to repair the situation earlier on.
The only problem with it is its usually the cause of The BSoD; on Vista that is; and it should be considered a threat if your laptop/computer starts to freeze, lagg or just generally play up.
