The GetStatus method retrieves the current status of the storage medium.
Syntax
HRESULT GetStatus(
DWORD* pdwStatus
);
Parameters
pdwStatus
[out] Pointer to a double word containing the status information. The following status values can be returned by the pdwStatus parameter.
| Status | Description |
| WMDM_STATUS_READY | The medium is in an idle ready state. |
| WMDM_STATUS_BUSY | An operation is ongoing. Evaluate status values to determine the ongoing operation. |
| WMDM_STATUS_STORAGE_NOTPRESENT | The medium is not present. For devices that support more than one medium, this value is only reported from the IMDSPStorageGlobals interface. |
| WMDM_STATUS_STORAGE_INITIALIZING | The device is currently busy formatting media on a device. |
| WMDM_STATUS_STORAGE_BROKEN | The medium is broken. For devices that support more than one medium, this value is only reported from the IMDSPStorageGlobals interface. |
| WMDM_STATUS_STORAGE_NOTSUPPORTED | The medium is not supported by the device. For devices that support more than one medium, this value is only returned from the IMDSPStorageGlobals interface. |
| WMDM_STATUS_STORAGE_UNFORMATTED | The medium is not formatted. For devices that support more than one medium, this value is only reported from the IMDSPStorageGlobals interface. |
Return Values
If the method succeeds, it returns S_OK. If it fails, it returns an HRESULT error code.
| Return code | Description |
| E_INVALIDARG | The pdwStatus parameter is an invalid or NULL pointer. |
| E_FAIL | An unspecified error occurred. |
Remarks
You must always call this method before attempting to interact with a storage medium. The status value returned is WMDM_STATUS_BUSY if some other interface has invoked an ongoing operation. You can evaluate the value returned from this call to determine if the status value specifies an ongoing operation invoked from the IMDSPStorageGlobals interface.
