Routine Description:
This routine implements the COM method for testing a resource to see if it is 'manageable' by the HSM (Remote Storage) system. (Only NTFS-formatted volumes which support sparse files and reparse points are considered to be manageable by Sakkara.) If the resource is manageable, it initializes the resource object.
Arguments:
pFsaServer - Interface pointer to the FSA service that is scanning this resource.
path - The long ugly PNP name that can be used if there is no drive letter for the resource being tested (i.e., it is mounted as a volume without a drive letter).
dosName - The drive letter (if there is one) of the resource being tested.
Return Value:
S_OK - The call succeeded (the resource being tested was found to be manageable, and the resource object was initialized).
FSA_E_UNMANAGEABLE - Thrown if the resource being tested for manageability is found to be unmanageable.
FSA_E_NOMEDIALOADED - Thrown if the resource being tested for manageability is a removable type of drive and no media is presently loaded.
E_POINTER - Thrown if the path argument passed in is null.
Any other value - The call failed because one of the Remote Storage or Win32 API calls contained internally in this method failed. The error value returned is specific to the API call which failed.

/*++
Implements:
IFsaResourcePriv::UpdateFrom().
Routine Description:
This routine implements the COM method for updating a resource object from another. It is generally used to update a resource contained in the manageable resources collection from a 'working' resource which was just created during a scan for resources. Note that both source and target resource objects must represent the same physical resource.
To capture the latest information about the resource, only the owning FSA and path info is updated from the source resource object. All other resource info is updated via a direct query contained within this method. This technique allows for capturing any updates made by the user since the scan was run.
Arguments:
pServer - Interface pointer to the FSA service that is updating this resource.
pResource - Interface pointer to the resource used as the source during the update.
Return Value:
S_OK - The call succeeded (the resource being tested was found to be manageable, and the resource object was initialized).
E_UNEXPECTED - Thrown if the id's (Guids) for the resource to updated and the source resource do not match.
Any other value - The call failed because one of the Remote Storage or Win32 API calls contained internally in this method failed. The error value returned is specific to the API call which failed.
