I have a VM running 2008 64-bit SP2 with 40 GB C drive originally. The VM is ESX 4.1. I added 5 GB to the hard disk (only one used for C drive). Then rescanned the disks on the VM. The extra 5 GB became available and then I expanded the C drive. The 5 GB became integrated into the C drive. However, it is only showing when looking at the graphic of the C drive, meaning that in Disk Management. In the list of drives in the middle window, the 5 GBs isn't showing.
Screenshot of Disk Management attached. The graphic shows 45 GB. The list of drives shows C still only has 40 GB.
I've tried rebooting and cehcking Event logs. Don't see anything out of the norm.
