Unable to boot - Safe Mode stops after crcdisk.sys

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.

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.

Wow people like you drive me nuts! Don't belittle the poster because you don't understand his situation. I am running into the exact same problem due to malware. The problem is bad enough without snarky dorks playing the know-it-all and throwing insults around.

Iam having the same problem, with two Windows 7 machines failing to start up at the same time.  I had a power failure, and found that the many "normal" troubleshooting cases I tried, including a fresh Windows 7 reinstall, all failed.  All of the machines uses SATA drives, one of the machines booted from an SSD drive.  I've experienced many many power failures and never had a problem the CHKDSK didn't fix, but in this case even a fresh install from the Windows 7 install disk would not fix the problem.  I reset the CMOS, removed the battery from my motherboard, tried every repair option I could find.  Eventually I disconnected all hard drives, bought a new drive and put that in, and installed Windows 7 on it.  But when trying to reconnect the old drives, one at a time, I could not even reformat the SSD drive, until I took it to my laptop  (a third machine, it's looking good at  96% complete).  The fact that the same hardware has two different results depending on which Win 7 machine I try to use it from tells me it's a problem with the original machine.  Yet I reset the BIOS settings, removed the battery, etc.  I don't get it.

The way this happened to two of my machines at home, and possibly a third at work (I'll investigate tomorrow) all at the same time, combined with the user above who reported it happening to 12 machines, tells me this is something other than a drive failure problem.  It's not hardware, unless a software update problem fried these drives. I believe all of the drives were SATA drives, so perhaps there is a bug in a Windows Update SATA driver or something, so that they were all put into some form of error state at the same time. 

At any rate, I found the message from Malkeleah to be thin on reading the problem and thick on abusing the poster who was trying to be helpful. I would report him for posting a message that offered no help but only insults, but it seems he is the moderator.  I agree that the long reply was not helpful because it was a shotgun reply trying to hit a target somewhere, but at least he was trying to help, and none of the insults help resolve the issue, which seems to me to be two-fold:

1. some update, perhaps SATA driver, results in an unbootable hard drive.
2. crcdisk.sys cannot deal with this situation and hangs.

If the second problem was at least detected and resolved, perhaps it could report whatever the condition was that would have otherwise put crcdisk.sys in that state, and that would provide a clue here.

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.
