不同类型的存储设备通常需要相同的服务。 本部分不重复为每种设备类型提供这些服务的 IOCTL 请求，而是定义一组标准服务以及存储设备经常需要的设备控制代码。 The I/O control codes defined here have the form IOCTL_STORAGE_XXX and they replace the IOCTL_DeviceType_XXX control codes, where DeviceType was DISK, TAPE, or CDROM. For example, IOCTL_STORAGE_RESERVE replaces IOCTL_DISK_RESERVE, IOCTL_TAPE_RESERVE, and IOCTL_CDROM_RESERVE. The IOCTL_STORAGE_XXX control codes have identical values for function code, transfer method, and required access as the previous disk, tape, and CD-ROM codes. 唯一的区别是设备类型。
存储类驱动程序会启动其中一些请求，但通常是一个应用程序。 存储类驱动程序必须处理部分或全部请求，具体取决于存储设备的类型。 如果不存在存储类驱动程序，应用程序可能会直接向端口驱动程序发出请求。

| IOCTL_STORAGE_GET_HOTPLUG_INFO | 检索指定设备的热插拔配置。 |
| IOCTL_STORAGE_GET_LB_PROVISIONING_MAP_RESOURCES | The IOCTL_STORAGE_GET_LB_PROVISIONING_MAP_RESOURCES request is sent to the storage class driver to determine available and used mapping resources on a storage device. |
| IOCTL_STORAGE_GET_MEDIA_SERIAL_NUMBER | 查询 USB 通用父驱动程序以获取 USB 设备的序列号。 |
| IOCTL_STORAGE_GET_MEDIA_TYPES | 返回有关软盘驱动器几何图形的信息。 |
| IOCTL_STORAGE_GET_MEDIA_TYPES_EX | 返回有关设备支持的媒体类型的信息。 |
| IOCTL_STORAGE_GET_PHYSICAL_ELEMENT_STATUS | The IOCTL_STORAGE_GET_PHYSICAL_ELEMENT_STATUS control code queries for and returns the physical element status from a device. |
| IOCTL_STORAGE_LOAD_MEDIA | 导致媒体加载到调用方已打开进行读取或写入访问的设备中。 |
| IOCTL_STORAGE_LOAD_MEDIA2 | Causes media to be loaded in a device that the caller has opened with FILE_READ_ATTRIBUTES. |
| IOCTL_STORAGE_MANAGE_DATA_SET_ATTRIBUTES | This IOCTL_STORAGE_MANAGE_DATA_SET_ATTRIBUTES request is used to send a manage data set attributes request to a storage device. |
| IOCTL_STORAGE_MCN_CONTROL | Temporarily enables or disables delivery of the custom PnP events GUID_IO_MEDIA_ARRIVAL and GUID_IO_MEDIA_REMOVAL on a removable-media device. |
| IOCTL_STORAGE_MEDIA_REMOVAL | 锁定设备以防止删除媒体。 |
| IOCTL_STORAGE_PERSISTENT_RESERVE_IN | 泛型存储类驱动程序（classpnp.sys）公开 I/O 控件（IOCTL）接口，用于发出持久保留 In 命令。 |
| IOCTL_STORAGE_PERSISTENT_RESERVE_OUT | 泛型存储类驱动程序（classpnp.sys）公开 I/O 控件（IOCTL）接口，用于发出持久保留 Out 命令。 |
| IOCTL_STORAGE_PREDICT_FAILURE | 轮询设备故障的预测。 |
| IOCTL_STORAGE_PROTOCOL_COMMAND | A driver can use IOCTL_STORAGE_PROTOCOL_COMMAND to pass vendor-specific commands to a storage device |
| IOCTL_STORAGE_QUERY_PROPERTY | A driver can use IOCTL_STORAGE_QUERY_PROPERTY to return properties of a storage device or adapter. |
| IOCTL_STORAGE_READ_CAPACITY | The IOCTL_STORAGE_READ_CAPACITY request returns the read capacity information for the target storage device. |
| IOCTL_STORAGE_REINITIALIZE_MEDIA | A driver can use the IOCTL_STORAGE_REINITIALIZE_MEDIA control code to reinitialize/erase a device. |
| IOCTL_STORAGE_RELEASE | 释放以前保留的设备，以便在支持多个发起方和保留设备的概念（如 SCSI 总线）上的调用方独占使用。 |
| IOCTL_STORAGE_RESERVE | 在支持多个发起方和保留设备（如 SCSI 总线）的概念的总线上声明调用方独占使用的设备。 |
| IOCTL_STORAGE_RESET_BUS | 重置 I/O 总线，并间接重置总线上的每个设备。 |
