What Jumper setting should i have for the Harddrive when using a firewire external enclosure? -Slave. -CableSelect. -Master. -Master w/Slave present. I have a WesternDigital 120GB using FIREWIRE connection (6pin to 4pin) to the ilink (s400) on my sony laptop. I have it on CableSelect.. but it keeps disconnecting and its buggin' the crap out of me. So anyone know whats the real deal behind this?
