Hi - I have a problem. We are on a customer site for an install. The vms all run W2009 R2, and have 2 partitions, a C and d drive. On one of the vms the d drive in inaccessible and showing access denied in the guest OS. This is a serious problem. Is it likely to be a lock file or something else? We shut the system down without any issues when we built it at base, so I don't know what's happened. The vm boots and starts up fine otherwise. I have a few things to try tomorrow but I haven't seen this before and hoping someone out there has. I could restore a backup of the d drive onto a new virtual disk and change the drive letters but would prefer to fix this one partly for the customer and partly because I want to know for the future.
Many thanks in advance.
If you are able to power up the VM and the virtual disks are not shared (e.g. MSCS), then it's most likely a guest OS issue you see. Please provide some further details about the VM in question. Did the guest work previously? Are you able to access the drive properties as the local administrator? How does the disk show up in the Windows Disk Manager?

Shows up in DM ok, just can't access it. Shows as zero size. I haven't seen this before so just wondered if it's anything to do with the ESXi side - just wanted to eliminate it as a suspect. We've had the host powered down and restarted a few times previously without issue, this vm came up each time no problem.
Did you try removing the vmdk (not deleting)and adding it back.
Also check if the disk is online in windows.
Looks like a W2008 UAC issue. Finally having had time to search on it, it seems fairly common.
Thanks anyway.
I have same issue and i had talk with vmware support according to them log ticket with Microsoft as this is OS side issue..

Hi guys!
I need your expertise regarding our vsan cluster. Can someone help me on these issue
We have a Virtual Machine running on windows server 2008. It is an sql server. On this vm, it has 5 partition. There is one partition that always disconnected or inaccessible so our remedy is to restart the vm.
Our boss is annoyed why it always keeps happening. This vm is has an schedule IDPA backup creating snapshot. Is creation of snapshot reasons why the partition got disconnected or suddenly inaccessible?
