What is SPTI?

SPTI is an alternative to ASPI and is used to read DVDs with a Windows SCSI interface. It is known for its high reading speed and ability to quickly skip bad sectors. It is used by many popular DVD-Cloner applications to make copies of DVDs.

SPTI stands for SCSI Pass Through Interface, and it is a Windows-specific interface that allows access to the SCSI bus. It is used to communicate with SCSI devices such as hard drives, CD-ROMs, and DVD-ROMs. SPTI was introduced with Windows 95 and is still supported in current versions of Windows.

SPTI is a low-level interface, so it requires a driver for each device. The driver is responsible for translating the SCSI commands into a format that the operating system can understand. SPTI drivers are normally provided by the device manufacturer, but some third-party drivers are available as well.

SPTI is popular with DVD-Cloner applications because it allows them to access the DVD-ROM drive directly, without going through the Windows file system. This makes it faster and more efficient than using the Windows file system. It also allows the application to read data from the disc at a much higher speed.

SPTI is also useful for skipping bad sectors on a disc. When a sector is unreadable, the application can simply move on to the next one without having to wait for the operating
