Specs: Windows 7, Pent4 dual quad 4 gigs
I just installed a use hard drive that had 2 partitions on it. This is an extra drive for data or backups. I am running a PC with Windows7 Professional. When I go to Computer management and then Storage, Disk Management, I show one partition healthy (Primary Partition). There is a 199 GB Unallocated partition that I want to format and create a usable partition but when I right click on it, there are a bunch of greyed out options such as: New Simple, New Spanned, New Striped, etc.
How can I utilize this 199 GB of disk space? When I right click into the 80 GB healthy partition that I want to extend the volume but when I try, I get An unexpected layout change occurred external to the volume manager. I need help.

Your description of adding a drive and then describing the partitioning is a bit confusing. You state you have two drives but you talk of only one.

Sounds like you are saying you have one drive that has a primary partition and unallocated space.

Make sure every disk is valid by running chkdsk /r on every partition. Then please clarify what you see

Thanks and my apologies for the confusing post. I am dealing with one hard drive that is apparently a Dynamic partitions. There are three partitions. I was able to Format one of them but now they show up with the same drive number on each separate partition. I am running chkdsk now through the Windows interface with both boxes checked. Hopefully when it finishes I will be able to see only one drive letter for this drive, or at least three different ones. Hope this is not confusing now.
Can I format this Dynamic Drive back to a basic hard drive? My end use is intended to be 2 partitions, one for cache files for PhotoShop and Capture NX2 and the other partition for backups and whatever. Thanks again for your timely and thoughtful response.

After running Chkdsk the Disk Management Software still shows the drive has 3 partitions all with the same name....strange as hell. When I go into My Computer, that shows all drives, the drive I want to partition shows 2 partitions with no drive letter. It is also a dynamic drive and I am unable to format it. I hope I don't have to write the drive to zeros with killdisk or something like it.
What is going on? Anyone know?

I assume you have TWO drives in the system with one being the added drive that is dynamic and the other being the original drive with the OS on it.

Go into disk management and wipe out all partitions on the drive and set to basic disk. Then partition as you desire. You don't need killdisk to do this.

Only disk management gives you the true drive picture. What you see in My Computer is the end result of what was setup in disk management. So when you say you see a drive in My Computer you wish to partition you can't because you are already seeing the partition.

Agreed. As Wanderer says, just delete the partitions and begin as you would with a new hard drive and set it up as you like from scratch.

You have to be a little bit crazy to keep you from going insane.

There is not an option to delete these partitions. They are apparently Dynamic partitions but the text when you right click on each partition is grayed out. I am going to pull the drive and replace it with another. Thanks for your thoughts and help guys.

It used to be a difficult to change a Dynamic Disk to Basic. I Googled it a few years ago. You might try that.

If Disk Manager will not let you delete the partitions then use Windows 7 install disk to delete the partitions: Install>Custom>Partition/Format then after you delete the partition (unless you need to reinstall) back out of the install and use Disk Manager to manage the unallocated space left behind.

It sounds like your partition change to spanned volume, to convert a dynamic disk to basic is simple, but if the dynamic disk contain spanned volume, RAID 0,1 5 it is hard to convert without data loss, I think you could try this dynamic disk converter, use the second method to clone your spanned volume to a basic disk. By this way it will keep your data safe. You could refer to this tortral "clone dynamic volume to basic disk"
