Expanding space on a VMWare virtual disk

We have a virtual server with two hard drives.  The C:\ is out of space.  It is thick provisioned.  So I shut it down this morning to add more space to the drive, however the ability to adjust the drive size is greyed out.  The storage server has plenty of excess capacity, but I don't seem to be able to adjust the size.  Any suggestions?

Sure, the issue is more thank likely 1 of 2 things -> the VM has snapshots associated with it, OR the virtual disk is an IDE SCSI Controller type disk (and needs to be LSI Logic). Once you verified both of those are not the case, you should then be able to resize the disk, then use a 3rd party tool (like GParted) to expand the partition within the guest OS (VM). Or, if it's a W2K8 or Win7 VM, you can just go into Disk Mgmt, rt-click on the partition and select Extend.

Probably the easiest thing to do is download/use vCenter Converter Standalone and, during the conversion wizard, you have the capability to resize the disk to what you want it.

If you have a IDE disk that needs converting (you check by rt-clicking on the VM -> Edit Settings -> SCSI Controller), see here:

If you have snaps, you can delete them in Snap Mgr (rt-click on VM -> Snapshot -> Snapshot Mgr) or just use vCenter Converter, which, along with the abiltiy to change the disk size, will also consolidate the snaps for you:
