About a while ago I ran chkdsk to check and recover bad sectors and fix system files and it then froze at 43% on stage 5 of 5. I left it on through out the night and I went to school and came back it was still at 43%. I then manually shut down the computer and ever since I have been trying to fix the problem. It was the second time I ran chkdsk on this pc while having windows 7 I usually run chkdsk every month or so to make sure everything is functioning right. After my problem occured I have tried so many things i have ran spinrite,I have reinstalled windows, I have tried to run chkdsk on safe mode, I have tried sfc/scannow, and chkdsk /p and all of these things did not fix the problem. Chkdsk /p was the only thing that didnt even try to fix anything because it said invalid parameter. Also when I reinstalled windows 7 on my pc then chkdksk froze at 49% on stage 5 of 5. I even ran diagnostics from the bios and I use Seagate Seatools and both diagnostics said my hard drive was perfectly fine. I also tried running chkdsk from the windows 7 cd and for some reason it completed in less than 2 hours. I then ran chkdsk from the pc and it then froze again this made me think that there had to be something wrong with my pc. So I was wondering how can I get chkdsk to complete perfectly from my pc again instead of using the windows 7 cd each time.

OK, here is the link the the article: Windows 7 - How to repair Bad Sectors reported by chkdsk

Now you know that a "Full" format using the Ultimate Boot CD will get rid of the bad sector. This was one of the major stumbling blocks, that is to say trying to find a free software utility able to do a Full format and not screw up the Master Boot Record.
My next step is to finish the documentation. This part of the task is where what to perform, the various options to choose and the exact sequence of steps took me a lot of additional time to get viable results.

I did what you told me to do. I added a few of my own steps to yours. When I created the partition it didnt format so it stayed as RAW. I found out a little trick that if I were to go to my computer and run check disk on "test" it would say that it wouldnt be able to. For some reason each time I were to do that after I restart it Check disk runs automatically on test and "fixes errors." Since this wasnt the first time I didnt even run check disk again to scan for bad sectors I just went straight to the boot cd. I deleted test using the cd and created test again so the error were to come back. The cd told me I couldnt use the partition yet so I restarted the cd. Then i was able to mess with the partition so I then ran the full format on it and it completed without any problems. After that I booted Windows 7 and ran check disk on Test for the first time since i deleted the partition using the cd. Check disk ran perfectly and said that it didnt find any problems. It also didnt correct the volume bitmap like it always does. Lastly, I deleted Test like you said and made it unallocated space which now makes me ready for your next step.
I just thought of something you can do that might just save us all a lot of work.
The area on your hard drive currently identified as “Unallocated” as you know contains the bad sector.
You should be able to prove this by using the unallocated space (temporarily of course) to create a new NTFS partition (label it “Test”), format using the “Quick” format option. Next run check disk on this partition and it should fail at stage 5 (free space).
If you are able to reproduce the check disk error then reboot your laptop using the “Ultimate Boot CD”, again in the upper left of the Ultimate Boot CD desktop you show see the 'My Computer' icon. Right click and select 'Disk Management' and verify for me that you can see the “Test” partition.
Now using ‘Disk Management’ reformat the “Test” partition (NTFS) using the “Full” format option. This will take a while so make sure you connected to AC power and not running off the battery. Once the format has completed remove the boot CD and reboot to Windows 7.
From Windows 7 run check disk on the now newly formatted “Test” partition. If no errors are reported then the bad sector has been mapped out of the MFT. Don’t try to expand the Windows partition as the second you do the mapped out sector information will be lost and check disk will fail. So at this point delete the “Test” partition and return it to “Unallocated” space.
**I’ll wait to hear what your results of the above task is.**JS

I configured a computer with a single hard drive (Western Digital Raptor) that while not the same capacity is partitioned to match your laptop's partition arrangement including the backup partition an unallocated space.
To repair a bad sector (sector is mapped out and replaced with a spare sector in the Master File Table "MFT") the detection and repair process can only only be accomplished by formatting a partition using what is called a "Full" format, Windows 7 only does a "Quick" format during the installation process so bad sectors are undetected mine fields waiting to explode.
No my drive does not have any bad sectors yet (I hope), therefor I can only simulate the process you will need to do. Which is to:
Sounds simple but its not. Took me more than 2 dozen attemps using various approaches to get it right. That why the documentation is so important.
Will it work for your problem, well theoretically yes but in the end you will only know for sure when you run checkdisk.
As to how soon I finish, well this is the third major rewrite of the documentation/article, I've delayed a number of other tasks, I'm a independent software beta tester and just received notice other another beta, plus I have other forum posts I participate in. So I'm streched a little thin at the moment.
