Hard drive issue won't boot

I have an 2nd HDD with Win XP on a dual boot.  This is just for my games and nothing else.  It has been booting up fine and now out of nowhere it goes to boot and I get the error "windows/system/config/system is missing"  and it tells me to put in my windows disk for repair.  When I boot to my main drive and I try to copy any files from D to C I get the "Data Error Cyclic Redundancy Check"  and D drive is SLOW in doing anything.  It's been regularly scanned for viruses so that's not it.  Is there a solution without formatting again?
If I have to format, I will, but I'd like to know what caused it.

If the drive is using ntfs as file system, run chkdsk driveletter: /x on it. If that doesn't resolve the issue, use the HD manufacturer's utility to test it, and if necessary run repairs on it. You'll find that utility on the UBCD.


If neither of the above helps, your drive needs to be replaced. You might be able to temporarily get it to run again using hddreg, but you should then still replace the disk asap.

Since it's slow aswell, my money is on it being damaged. Can be a case of just a few bad block in the wrong place.

Since you are considering just formatting it I assume there's no important data on it? Running checkdisk from command prompt might fix it for you;

chkdsk D: /f

/f to automaticly fix errorrs.
Newly released Acronis True Image 2019

In announcing the release of the 15th Anniversary Edition of Acronis True Image 2019, the company revealed that its artificial intelligence-based anti-ransomware technology – stopped more than 200,000 ransomware attacks on 150,000 customers last year.

CRC errors are bad news. It could even be physical damage to the disk. You can perform chkdsk /f /r on the disk, but this might result in the deletion of corrupt data.

The first thing I would recommend is to replace your IDE cable to the harddisk or try the disk in another system.
If that doesn't help, try a data recovery program like SpinRite (http://www.grc.com/sr/spinrite.htm) to save as much data as possible. Finally, try the chkdsk method (or formatting).

I hope this helps!
Do the following:

Put in your windows xp cd, and wait for it to load. when it gets to where you can install, then you press "r", to go to the recovery console. When you get out there and it saids "C:\Windows\", type the following:

md tmp
copy c:\windows\system32\config\system c:\windows\tmp\system.bak
copy c:\windows\system32\config\software c:\windows\tmp\software.bak
copy c:\windows\system32\config\sam c:\windows\tmp\sam.bak
copy c:\windows\system32\config\security c:\windows\tmp\security.bak
copy c:\windows\system32\config\default c:\windows\tmp\default.bak

delete c:\windows\system32\config\system
delete c:\windows\system32\config\software
delete c:\windows\system32\config\sam
delete c:\windows\system32\config\security
delete c:\windows\system32\config\default

copy c:\windows\repair\system c:\windows\system32\config\system
copy c:\windows\repair\software c:\windows\system32\config\software
copy c:\windows\repair\sam c:\windows\system32\config\sam
copy c:\windows\repair\security c:\windows\system32\config\security
copy c:\windows\repair\default c:\windows\system32\config\default

Then type "Exit".

- Reboot your computer in failsafe mode.
- When you get into windows, then first make sure you can see all system and hidden files.
- Then find the folder "System Volume Information" in the root of "C:\", and make sure that "Administrator" has full right to that folder.
- When you get access to the folder, then enter the folder "_restore{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}" inside the "System volume Information" folder.
- Inside that folder,  then enter a folder named "RPxx", that is older than the date where windows started to give you that error.

Copy the following to C:\windows\tmp:

when you have done that, then do this:

Now reboot your computer in the Recovery Console again, and type the following in the console:

delete c:\windows\system32\config\sam
delete c:\windows\system32\config\security
delete c:\windows\system32\config\software
delete c:\windows\system32\config\default
delete c:\windows\system32\config\system

copy c:\windows\tmp\software c:\windows\system32\config\software
copy c:\windows\tmp\system c:\windows\system32\config\system
copy c:\windows\tmp\sam c:\windows\system32\config\sam
copy c:\windows\tmp\security c:\windows\system32\config\security
copy c:\windows\tmp\default c:\windows\system32\config\default

Hope this can help you on the way.
Have done this with 2 computers and it worked on both.
sounds like a damaged hdd, you should scan with chkdsk /f or do a full scandisk. If there are bad sectors, then your hdd is damaged. You CAN fix the problem (temp.), but I can assure you the same problems will occur within a couple months again.....

Problem can be fix by: Harddisk Regenerator (if the problem = bad sectors)

Good luck
Checkdisk will not fix the"windows/system/config/system is missing" problem.

Psyclown's method will fix your problem.

You can reboot straight into windows after the step "Then type "Exit".", but you will be creating a new hardware profile and you may have to set up some software programs again.
chkdsk can fix the problem, particularly if files are corrupt and that is the case with a bad disk. psyclown's method should be used after the disk problems have been rectified , but they don't help much with a bad disk. CRC errors are a sure sign of a bad filesystem or disk.

That should do everyone, thanks.  I will figure out how to assign points.
