Disk IO protocol as defined in the UEFI 2.0 specification.
The Disk IO protocol is used to convert block oriented devices into byte oriented devices. The Disk IO protocol is intended to layer on top of the Block IO protocol.

| EFI_SUCCESS | The data was read correctly from the device. |
| EFI_DEVICE_ERROR | The device reported an error while performing the read. |
| EFI_NO_MEDIA | There is no media in the device. |
| EFI_MEDIA_CHNAGED | The MediaId does not matched the current device. |

| typedef EFI_STATUS(EFIAPI * EFI_DISK_WRITE) (IN EFI_DISK_IO_PROTOCOL *This, IN UINT32 MediaId, IN UINT64 Offset, IN UINTN BufferSize, IN VOID *Buffer) |
Writes a specified number of bytes to a device.
| This | Indicates a pointer to the calling context. |
| MediaId | ID of the medium to be written. |
| Offset | The starting byte offset on the logical block I/O device to write. |
| BufferSize | The size in bytes of Buffer. The number of bytes to write to the device. |
| Buffer | A pointer to the buffer containing the data to be written. |
| EFI_SUCCESS | The data was written correctly to the device. |
| EFI_WRITE_PROTECTED | The device can not be written to. |
| EFI_DEVICE_ERROR | The device reported an error while performing the write. |
| EFI_NO_MEDIA | There is no media in the device. |
