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 values can be returned in the pdwStatus parameter.
| Status | Description |
| WMDM_STATUS_READY | The medium is in an idle or ready state. |
| WMDM_STATUS_BUSY | An operation is ongoing. Evaluate status values to determine the ongoing operation. |
| WMDM_STATUS_STORAGE_NOTPRESENT | The storage medium is not present. For devices with more than one medium supported, this value is only reported from the IWMDMStorageGlobals interface. |
| WMDM_STATUS_STORAGE_INITIALIZING | The device is currently busy formatting storage media on a device. |
| WMDM_STATUS_STORAGE_BROKEN | The storage media is broken. For devices with more than one medium supported, this value is only reported from the IWMDMStorageGlobals interface. |
| WMDM_STATUS_STORAGE_NOTSUPPORTED | The storage medium is not supported by the device. For devices with more than one medium supported, this value is only returned from the IWMDMStorageGlobals interface. |
| WMDM_STATUS_STORAGE_UNFORMATTED | The storage media is not formatted. For devices with more than one medium supported, this value is only reported from the IWMDMStorageGlobals 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
This method must always be called before the caller attempts 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 IWMDMStorageGlobals interface.
