SCSI Pass Through Interface (SPTI) is an application programming interface (API) accessing a SCSI device. It is developed by Microsoft Corporation and is part of the Windows NT family of operating systems.[1]

Overview
The storage port drivers provide an interface for Win32 applications to send SCSI Command Descriptor Block (CDB) messages to SCSI devices. The interfaces are IOCTL_SCSI_PASS_THROUGH and IOCTL_SCSI_PASS_THROUGH_DIRECT. Applications can build a pass-through request and send it to the device by using this IOCTL.
SPTI is accessible to Windows software using the DeviceIoControl Windows API.[2]
ImgBurn offers SPTI as a method for accessing optical disc drives.[3]
