A storage filter driver (SFD) supports device-specific functionality not provided by a system-supplied storage class driver.If a storage class driver already exists for a particular type of device, it might be unnecessary to write a driver for a new device of the same type. Each system-suppli...
和任何其他內核模式驅動程序一樣, 記憶體篩選驅動程式的 DriverEntry 例程必須在輸入驅動程式對象中定義其 Dispatch 和其他進入點。 如有必要,SFD 可以呼叫 IoAllocateDriverObjectExtension 來配置適當大小的驅動程式物件延伸模組、將輸入登錄路徑複製到驅動程式擴充功能以供日後使用,並視需要與其他驅動程式決定的...
若要處理SrbType設定為SRB_TYPE_STORAGE_REQUEST_BLOCK的情況,篩選驅動程式必須在驅動程式上方所傳送的要求中設定StorageAdapterProperty識別碼時,針對IOCTL_STORAGE_QUERY_PROPERTY設定完成常式。 在完成常式中,STORAGE_ADAPTER_DESCRIPTOR中的SrbType成員會修改為SRB_TYPE_SCSI_REQUEST_BLOCK正確設定支援的類型。
当底层驱动程序(端口、类和附加筛选器驱动程序(如有))调用IoCompleteRequest时,存储筛选器驱动程序的IoCompletion例程将被调用。 存储筛选器驱动程序 (SFD) 的IoCompletion例程应返回STATUS_MORE_PROCESSING_REQUIRED,以防止对驱动程序分配的 IRP 进行完成处理,如果 SFD 在完成 IRP 之前将重复使用该 IRP,则应保留...
(not a file system filter driver) that uses a copy-on-write technique in order to create a shadow copy. The Volume Shadow Copy Service (VSS) orchestrates the shadow copy. The Volume Shadow Copy Driver, volsnap.sys, is a storage filter driver that loads on top of the storage stack below...
typedef struct _SFILTER_DEVICE_EXTENSION { PDEVICE_OBJECT AttachedToDeviceObject; //绑定的文件系统设备 PDEVICE_OBJECT StorageStackDeviceObject; //与文件系统设备相关的真实设备(磁盘) UNICODE_STRING DeviceName; //如果绑定了一个卷,这是物理磁盘卷名;否则,为绑定的控制设备名。
The FilterReceiveNetBufferLists function should return as quickly as possible. Before returning, the FilterReceiveNetBufferLists function can copy the received data into filter-driver-allocated storage or pass the buffer on by calling the NdisFIndicateReceiveNetBufferLists function....
or more file systems or file system volumes. Depending on the nature of the driver, filter can mean log, observe, modify, or even prevent the file I/O. Typical applications for file system filter drivers include antivirus utilities, encryption programs, and hierarchical storage management systems...
Well, if you look forward to checking bad sectors in the storage devices, you can do that too from CMD. Checkdisk utility checks for any disk errors and fixes them. In the CMD, you will have to use chkdsk, which will do the job for you. ...
