SCSI Pass Through Interface

1

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.

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. ImgBurn offers SPTI as a method for accessing optical disc drives.
