The Seagate Travan 40 drives come with an ATA Packet Interface (ATAPI) 
controller for communications between the host computer and the drive. The drive 
supports the QIC-157 standard interface.  

Note:  Refer to the QIC-157 Standard for detailed information about this interface.  

This chapter clarifies the use of several ATA-2 signals and ATAPI commands that 
are either vague or optional in the QIC-157 specification. 

The Seagate Travan drives provide a standard ATA-2 connector. The pin 
assignments for this connector are listed in the following table for your reference.
