Format (remove) HDD volume that is visible in Windows 7 Disk Management but not diskpart.exe

I'm trying to get iRST working on a SSD I installed in my lenovo u410.

As part of that process, I created a hibernation partition and was fiddling around with RAID/AHCI settings. I managed to make my computer unbootable. No sweat, I just restored it with Lenovo's 1 key system.

Now, however, I can't do anything with that hybernation partition! I can see it: Disk Manager View

(It's the 7.81 GB partition).

But when I try to delete it in Diskpart.exe to reclaim the space and try the formatting again I only see this: Diskpart View

I can't do anything with the partition in Disk Management either. Right clicking only shows the 'help' option.

Can anyone suggest a way to edit these partitions with windows or, at least, reccomend a program that might help me fix this?

Note, I'd rather not delete the 16 GB OEM partition that I believe holds the backup for this computer.

I can recommend Easeus Partition Magic for this.

You download the free Home Version here:

Easeus can handle hidden and locked partitions.

Wow, thanks. I've been very skeptical of third party managers, hence the trust of my question was using internal windows tools, but this was really a very good program. – PatKilg – 2012-10-14T21:26:58.603

In Windows, there are some freeware third party partition managers available. Examples that come to mind include EaseUS and Paragon. Do a Google search for 'freeware partition manager'

I would recommend using a Linux Live CD with gparted to perform this task. You will see the partitions mounted as /dev/sda1, /dev/sda2, etc. and you can delete the partitions from the partition manager GUI included on the Live CD. http://gparted.sourceforge.net/livecd.php
