Can't use/manipulate or delete unallocated space.

[upscale]

Windows 7, 64 bit. I've just added a new 4TB Western Digital hard drive. I divided the drive into two unallocated areas. The first area is 2048GB and the second area is 1678GB. This is not a boot drive.

I can subdivide the 2048GB area, partition and format it as I like. I can just as easily delete and repartition it again as I like. I CAN'T do anything with the 1678GB unallocated area. This inability includes deleting it. The only option that's available is to look at it's properties.

I'm certainly not new at this, but I'm stumped for a solution. Any ideas?
Thanks

You can't delete unpartitioned space...

You need to use a GUID partition table (GPT). MBR only goes up to 2TiB.

The problem is I can't do anything with the 1678 GB unallocated space which is well under 2TB.

As I said, you need to use GPT. MBR can't deal with drives larger than 2TiB; it can't handle numbers large enough.

Yeah, you're right, I've got a 4TB drive, I wasn't thinking. Thanks

Well, I was too quick to post that it was solved. I've uploaded an image to Photo Bucket.

Whatever I do, I can't change, manipulate the 1678GB area in disk zero. I can edit the 2048GB area, but that's not what I want. I could convert other disks to GPT, but that option isn't available for converting drive zero. Any ideas?

I'm not sure how to do it in Windows. If you were using GParted it's pretty easy.

Sorry.

Windows 7, 64 bit. Well, I finally found the time to figure this out. In the search bar, I typed in 'diskmgmt.msc'. Right clicked on diskmgmt.msc and selected 'run as administrator'. When the disk management window comes up, right click on the 4tb drive partitions and select 'convert to GPT'. After that, I had full control of both drive partitions to delete, recreate and manipulate as I desired. ~ Not exactly as some instructions I've read, but close enough to get me to where I needed to be. The key was inputting diskmgmt.msc and running it as administrator.

Thanks for your time.
