Unable to boot - Safe Mode stops after crcdisk.sys

Malkeleah,

Man do you have issues.  I came here looking for answers to the same hanging post-crcdisk.sys issue in Vista and I run headlong into a supposed MVP with this kind of attitude.  The attitude guaranteed to keep someone like you out of management pretty much forever...and with good reason.

I have already tried using a boot disk to do a startup repair and it did not work.  The startup repair runs and says issues are fixed, but windows still stalls after a hard disk boot.  I have already purchased another hard drive and reinstalled windows and my machine is up and running again, so it is either the windows software or a failing disk.  Like I said before, though, I am able to read information off of the old disk.  Thank you for your help though, and I would welcome any other suggestions on how to get the old drive up and running.

Hi R-Ptaz,

There can be many reasons this error happens including disk corruption, some driver issues and

others.

Since you have 12 machines all with the same issue it sure sounds like a malware attack in your case.

It is possible that a driver up from Windows Update, an automatic updating program such as some

System makers load, or even antivirus/antispyware/security updates causes a driver corruption.

It could have been malware just waiting for an Update to attack or even a reboot to attack.

Certainly would do an intensive check for malware and then a format Clean install after backing up

any important data off the machine.

Please post back any feedback you can.

Hi Patrick Menge,

Try Startup Repair from the Recovery Console (if you have one) or from a Vista disk - if you do not

have a Vista disk you can borrow a friends (they are not copy protected) or make one. Also your

System maker will sell the physical disks cheap since you already own Windows.

Try StartUp Repair from Recovery Options and/or a Vista disk.

Also from the Command Prompt of Recovery or a Vista disk :

chkdsk /f /r

I have pulled out the "defective" hard drive and connected it as a secondary drive to another computer.  By doing this I am able to read all of the information on the hard drive.  That makes me think it is something in the windows software as well.  I didn't think my computer had a trojan at the time it went down, as I quite frequently check for them, but I guess you never know for sure.  If you are able to find an answer to the problem, I would really like to know.
