# size in bytes

$mb = [system.uint64] $vhdsize*1024*1024

hi,

 

if extend vhd file through script or gui such hyper-v manager, symptom encountered expected behavior.

 

for example, original vhd 30gb, extend 50gb, after extend, able find 20gb’s unallocated disk space @ end of disk.

 

by way, system behavior, need extend yourself, or can create new partition/volume.

 

in addition, if have 1 partition(c: drive) within windows server 2003 vm, not able extend system partition directly, because don’t support extend system partition in windows server 2003. more information, can refer following post.
