Server 2008 R2 - VSS Error 12305 adn 7001

VSS has not ran on my data drive for over a week now as I am getting the below errors:

4 matching event log records found in the 'Application' event log.

I disabled VSS on the data drive, but now I cannot reenable it I get the following error:

Failed to create a shadow copy of volume D:\

Error 0X80042308: The specific object was not found

I can enable VSS on the C drive..

I checked all the status of the vss writers and my volume\drives and everything shows healthy and online.

http://technet.microsoft.com/en-us/library/cc734563(WS.10).aspx details the error and a step by step on how to setup vss for the affected disk.
I would suggest you look in the registry to determine what volume you are dealing with.
1. Open the registry and look at the following location: HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices
2. Locate \\?\Volume{884707b0-4645-11df-ae4d-a4badb12399d} and verify the disk signature (1st 6 hex digits) in the Data column. (i.e. 5c 00 3f 00 3f 00)
3. Identify \Dos\Devices\<Drive Letter>: which is associated with the disk signature you found in step 2. This will tell you the disk letter of the mounted device in question.
4. Make sure the device associated with the volume ID is in fact attached to the system and available for VSS to use.
If this is assocaited with a USB or other removable disk, this could be the cause of the issue. Update me on your progress.

Thanks for the response - when following your steps, i did confirm that the disk in question is my data drive. It is mounted and showing as healthy in disk manager.

Last week I rebooted and was able to enable VSS on the D drive, it ran shadow copies up till Friday and now is failing again with the original error...

Have you tried to reregister the dll's for the VSS writer? I had a similiar issue and this was able to fix it.

Look in the system event log and see what you find on VSS. Also, verify the free space on your disk.

noxcho

Press start - cmd - run as admin.
Type mountvol and hit enter.
Find there in the list this volume: {884707b0-4645-11df-ae4d-a4badb12399d}
What drive letter does it refer to?

Hi

I am having the same errors on a Windows Server 2008 R2 Enterprise server but am unable to install the hotfix. When I try to install the hotfix I get a "The update is not applicable to your computer" message. I have tried both the x64 and ia64 versions of the hotfix on a couple of different identical servers and get the same message.

When I configure Shadow Copies on the E Drive and set the storage volume to C: or E: it works fine. However, when I set the Storage Volume to D:, which is the desired volume and try to create a snapshot (Create Now button) I get the following error (as in attached file VSS1):

"Failed to create a shadow copy of volume E:\.

Error 0x80042308: The specified object was not found."

Event Viewer immediately after gives me a VSS 12305 Event ID error with the following info:

Volume Shadow Copy Service error: Volume/disk not connected or not found. Error context: DeviceIoControl(\\?\Volume{d41e0ab5-dfb7-4a70-89cc-bff26150ed2e} - 0000000000000190,0x0053c008,000000000057EFC0,0,00000000002481F0,4096,[0]).

Operation:
Processing EndPrepareSnapshots

Context:
Execution Context: System Provider

When I go into the registry and go to HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices there is no volume with an ID of d41e0ab5-dfb7-4a70-89cc-bff26150ed2e listed. See attached file VSS2.

I have also attached the results of running mountvol. See attached file VSS3.

Please help. I need the Storage Volume to be the D Drive. I have 11 Server 2008 R2 servers with VSS working fine on 6 of them. The other 5 were working fine until some point in March, when they suddenly stopped. I have rebooted the servers a couple of times which seems to temporarily resolve the issue, but not for long.

Thanks
