I have handful of Win2k8 64bit vm's on esx5.5 update 2 that are showing "VMware Vista Physical Disk Helper" have the error 'This device is not present, is not working properly, or does not have all its drivers installed. (Code 24)'. The VMware Tools versions vary, either 9.4.0 build-1585188, 9.4.5 build-1598834, or 9.4.10 build-2068191.
Google has failed me for the most part. I can't find any concrete information on what this virtual device is or what it does specifically, except that it may be involved in creating quiesced snapshots.
Also, the device appears to be attached to the vmrawdsk service, which doesn't exist on the server. These VM's were not P2V, they were created from win iso.
Any guesses on what this is and how I might be able to fix it?
