Resize HDD portion from HDD 1 To HDD 2 ?

[boosters]

I have both Seagate internet HDD. Once is just 160GB and the second is 500GB (which recently bought). How can I merge the partition space on HDD 2 to HDD1.

I mean to say. My C drive is only have 5% space left, so my second drive which have 500 GB, i want to give 100GB to the C: drive which is my HDD 2. How can i do this way. All my partition is NTFS and running in Win 7 64 Bit. Please help.

1. Back up any important data on the second drive.
2. Right-click Computer > Manage > Storage > Disk Management
3. Right click on the second drive and pick delete partition.
4. Right click on the C drive and pick extend.

This assumes you didn't do anything out of the ordinary like put the page file on the second hard drive (if you don't know what that means, then don't worry, you didn't).

I think i have written something wrong..

I am asking::

1. I have 2 HDD, my first HDD is 160GB which my windows were installed on C drive and only 5% space was left.

2. My second HDD is 500GB, i have created the 100GB partition which is a D drive (label). I want to move that 100GB partition to the C: drive... That means HDD 2 (D Drive) to HDD 1 (C: Drive)

I hope you guys now understand, what i am asking..

Right. When you do those steps I posted, that will take the partition on drive d and delete it. It will then extend the partition on C to include the space from D. So you will end up with C drive that you currently have, and it will also have all the space from the second drive. There will no longer be a D, all of it's space will be merged into Drive C. If you only want to merge some of it then when you click extend, you can pick less of the space, say 100GB. That will take 100GB from drive D and make it available on C and you can then create a new partition D with the remainder. I hope that clarifies....
