Atapi compatible w/scsi



Hey folks, this could be considered a dumb question,

could i install an atapi (plexwriter premium) into a SCSI port?
i have an hp pavillion 505n and the extra slot says SCSI, not sure what the main Samsung sw248F is.
Basically, is the Plexwriter an option here?
ALso how do I know if its cable select?


would thread be of any help?
