I need some help trying to see if this is even possible. I have a security system that has an internal IDE hard drive and a SCSI port. The internal hard drive is not big enough to record all the data we want, so we need to buy about a 320 gig hdd. The connection is a 50 pin SCSI2 female connection. Is there a converter that would plug into the female port on the outside of the case that would go into an external IDE hard drive, or can someone think of an easier setup?
