Windows 7: Not able to access rest of 450GB hard drive space

Not able to access rest of 450GB hard drive space

Hi All,

I am stuck with a major problem in my new laptop, please someone help me to resolve this issue.

My laptop hard drive capacity is 500GB [approx 466 GB usable] which is not partitioned [single drive], after I reinstall windows 7 operating system the C: drive capacity reduces to 9GB!! I surprised how 17GB (approx) operating system get deployed on just 9GB partition.

Now my major problem is, I am not able to access rest 450GB of hard drive space. I have gone through all posting threads of this forum but unable to find solution for my problem.
Please find the attached snapshots.
I worried about this drive since rest all other drive marked as "healty", but there is no info about this space. I tried all other options which were explained in early postings to get it back online, unfortunately not able to succeed.

I even tried converting the basic disc into dynamic disc as the last option, but it warned me. Since I do not have sufficient knowledge about this option so I did not proceed further.

Please someone help me on how to resolve this issue.

Can you delete that partition (the 456gb one) then right click your C partition and click expand.
Does that work?

The 456GB partition looks deleted,but it'll rule out any quirks.

Hi Minotar,

Thanks for your quick reply. Unfortunately next time when I boot up my machine the OS got corrupted, so I need to reinstall OS once again. That resolved the issue and I got full access to hard drive.
