Extend C: partition on Windows 2008 VM Machine

In VMware 5.1, I have extended C: partition of windows VM machine.
But in windows Disk Management, I do not see the "Unallocated space" that should show up.

I wonder if it has to be rebooted.  it is a production server.

Windows will not see the additional partition or added drive until you reboot. Reason is that there is a small driver veered to be installed.
In general I do not recommend tampering the drives while Athens VM is running.

Has the disk (virtual disk) , e.g. the vmdk size changed?

virtual disk changes are hot plug, and do not need a reboot.

if the vmdk size changed, right click on disk management and select rescan disks

so if I extend the drive from VMware edit settings. then wait a week to restart the server, will that hurt the server?
Seth SimmonsConnect With a Mentor Sr. Systems AdministratorCommented:
what driver are you referring to?  i've never heard of windows needing to reboot once the disk was extended.  rescan the disk and the new space will appear then extend the volume

Sounds like you did that already, so wait is OK. Under normal scenario I recommend downing the VM and then do the drive ant boot your VM.
