I have a 1TB Lacie external HD for my IMac connected by a firewire 800. I have an older Seagate Free Agent Pro 500GB drive w/ eSATA & USB cables. I tried to daisychain the Seagate to the eSATA connector on the Lacie and it isn't recognized. I'm looking for help to make this work so I don't have to use the slow USB connection on the Seagate.

I don't think eSATA or USB can be daisy-chained, but Firewire can....not that it helps your situation......if you find out otherwise I'd love to know

Yeah, eSATA isn't going to work through daisy chaining.

Daisy chaining across busses is possible, I suppose, but I've never heard of anyone implementing it in consumer gear.

Daisy chaining with SCSI. Fun days.

eSATA external drive on the Mac? Good luck. Get an adaptor I guess.

Yeah, good point, there's no eSATA on iMacs and no expansion options that I know of to add it, either.

SCSI, now those were the bad old days. Those huge, fat cables, termination problems. LOL.

Every time someone tells me eSATA is going to replace FireWire, someone asks how they can daisy chain something. So frustrating that a superior product gets swept under a rug once again.

eSATA offers superior performance and it's cheap. But it isn't better at everything. Besides daisy chaining it has until recently also lacked bus power. It's also very limited in terms of max cable length.

eSATA will not replace FW. They do different things. eSATA is nothing in the pro A/V world, FW is ubiquitious there. eSATA is all about native disk interfacing, FW is more expensive and takes a performance hit because it requires bridging. That said, in the near future we will see usage of FW will decline, eSATA's will increase. Once USB3 is available I'm pretty sure that's what the entire consumer world along with a good portion of the pro world will switch to. It will be simple, cheap, and fast. And as the 90% Windows market share shows, 'good enough' is all most people care about.
