GusBiz,
Don't know that drive you have but I am pretty sure the port is an RJ11, which looks similar to an Ethernet or Firewire port which is an RJ45. The main differance being the number of connectors, 8 for RJ45 vs. 4 for RJ11, but don't quote me on that.

The drive almost certainly talks to the PC via RS323 serial communications, not Ethernet or Firewire. If you don't have a serial port on you computer you can purchase a USB to RS232 adapter quite cheaply. Read the reviews, some are not any good.

Once you have a serial port you will need to make an adapter with a RJ11 on one end for the drive and a female 9 pin D-Sub on the other end to connect to the serial port.
The pinout for the RJ11 port should be printed on the drive or at the very least found in the manual. Look up the pinout for the serial connector and connect the corresponding wires form the RJ11 end and you should be good to go.

Hope that makes some sort of sense. Let us know how it goes.
