Windows Vista freezing at crcdisk.sys

Hello Experts,

I have a dell laptop  (Inspiron 1550 "i think"...not at home right now so cannot look at the model number, will add this later when I get home.)

The computer keeps randomly freezing when I boot normally.  It will freeze within the first few minutes of the OS loading.  I was able to boot into safe mode yesterday various times and it wouldnt freeze at all but then as the night progressed it would continually hang at crcdisk.sys.

I am thinking that this may be a hard drive that is failing but am not quite sure.

I also thought that it may be a driver issue because it was freezing only when it was running normally and not in safe mode but now it wont even boot into safe mode without freezing at the crcdisk.sys.

Another thing it is doing its running chkdsk almost every time it boots.  I dont see any errors when it does run chkdsk so..??

Please advise

Thanks in advance.

If you are able to use the system in Normal Mode, Please go to the Control Panel, Network and Sharing Center and then click on "Manage Network Connections", Right click on the Network Adapter and click on Properties and then go ahead and uncheck the option which says "TCPIP Protocol IPv6" from the list. Click on OK and restart the system once and then try by booting into Safe Mode, you ideally should be able to boot without getting stuck at the crcdisk.sys file.

Coming to the part of the system freezing up, you did mention that the system was working fine in the Safe Mode, so I would guess there could be a startup item or some software causing the issue here, so try disabling the startup once and check if that helps or not. You might have already tried but still check once.

Thanks for the effort on this one.  I will try to do this once I get home and get back to you on this.  Yes it was booting into safe mode for awhile then it stopped.  While I was in safe mode it never hung once that I can recall so...  (and now it just hangs and wont go into safe mode..)

I will get back to you asap.  Also I welcome any other possible solutions to try on this one.

You are welcome, will await for your response.
Hello Posh,

I tried that and its still freezing at crcdisk.sys.  When I do boot into normal mode it does say  "dell wireless wlan card wireless network controller stopped working and was closed" everytime I boot.

Also every time I boot it goes to "checking file system on c:" which I can either let run or cancel if I hit a button within 10 seconds or so.

Does this give any more info to anyone?



Even though it says that I am still able to connect to the internet wirelessly (I never use hard wired on this notebook)
You have not responded to my comment about hard drive errors that your information is also pointing to.

Hello ThinkPads

I am in the process of doing that now (I think)

I am following the directions on this thread -

Other then that I dont know of any HD test that Dell would supply me with.  This pc is not under warranty any longer.  I may have to do a search on the net.

I will report back with any results that come back from the tests (using the F8 key to access)

I was given error code 0412  (2000-0142)

Hard Drive 1 - Self Test Unsuccesful.  Status 79

The given error code and message can be used by Dell Technical Support to help diagnose the problem

Damn, this probably means the HD is shot.  
So you received the 2000-0142 error on the Dell Diags, which means Drive Self Test Failed, you can try to back up the data and try the below mentioned steps if you still want the system to work for sometime without having to replace the HDD.

Backup the data to an external Source, if possible and then go ahead and do a Debug reinstallation on the machine, will work for sometime, but the time frame that the system would work with the same HDD would depend. Could work for a day,week, month or even for a year. Would totally depend on the number of bad sectors on the HDD.

Let me know if you need the debug commands for the HDD.

Hi Posh,

Thanks for the help.

I dont know how to do exactly what your mentioning and I will give it a shot.  There is nothing on the pc that I need to back up so I have nothing to lose.  

I need exact instructions on how to "debug" the HD.  Thanks so much I really appreciate it.  Maybe I can get some more life out of this thing.

Also one other question.  When I do need to replace the HD can I replace it with this one -

Western Digital Scorpio Blue WD3200BEVT 320GB 5400 RPM 8MB Cache 2.5" SATA 3.0Gb/s Internal Notebook Hard Drive

It just has to be any 2.5 sata drive right?  Should I upgrade to a 7200 rpm drive or keep it at 5400 rpm.  I wasnt quite sure If I COULD do that or if it wouldnt work etc.  Also I wanted to make sure I didnt need to buy a specific DELL HD as they are way more expensive for the most part.



Regarding the HDD that you had the Query "Western Digital Scorpio Blue WD3200BEVT 320GB 5400 RPM 8MB Cache 2.5" SATA 3.0Gb/s Internal Notebook Hard Drive" I would be able to let you know if you can provide me with the exact model of your system, cause need to check the system model specifications to make sure that the HDD that you are looking for would work, coming to the part for doing the debug and then the re-installation on the system, just follow the instructions from the links below,  you can print for reference and then do the reinstallation. You have to be precise on the commands for it to work or you would have to redo the complete steps again.

Debug Script For SATA HDD

For Reinstalling the Windows back, you just need to put the OS disk into the machine and allow it boot through the disk and follow the on-screen instructions.


Thanks Posh.

I will have to track down the OS disk as its my sisters pc.

Its an Inspiron 1525
So the hard drive  being shot is where I was way back in the thread here (I am not surpised). If the directions for restoring don't work, let us know. ... Thinkpads_User

The HDD that you had selected "Western Digital Scorpio Blue WD3200BEVT 320GB 5400 RPM 8MB Cache 2.5" SATA 3.0Gb/s Internal Notebook Hard Drive" will perfectly fit the Inspiron 1525 and will work fine, you can compare it with the "Dell 320 GB 5400 RPM Serial ATA Hard Drive for Dell Inspiron 14/ 15/ 1525 / Vostro 17/ 1014/ 1015 Laptops" cause both have the same technical specifications except that the Dell is priced more than the Western Digital.

So you can put the WD into the system when you need to without any issues and use the system. before you go for the new HDD you can check and do the Debug should get some more juice off the current hdd.

Really appreciated the help to both of you.  I felt Posh was much more articulate and detailed which is very helpful to most people (who are not super computer literate but can walk themselves through detailed directions)  I really appreciated both of you helping me out.  Thank you!
