How long should it take to copy 36GB worth of data from an internal
hard-drive to an external hard-drive via firewire? I know you're not
going to get 400Mbps with drive to drive copying because the PCI BUS
and the hard-drives themselves are a lot slower than that. But 6
hours?? That seems ridiculously long to me. But that's exactly how
long it took me to backup 36GB worth of data to a new external
firewire drive I got today. Does anyone know if that sounds about
right? Or is something seriously wrong with my Firewire setup?

If the system is working properly, it should only
be a bit longer than with a pair of internal drives.

You can in fact get surprisingly high rates with drive cloning with
each drive on its own ribbon cable with Ghost or Drive Image.

Yeah, something is wrong.

Using what to do the copy program wise ?

Nar, hopeless. You shouldnt get a result like that even
between two PCs with a 100Mb lan between them.

Yep, something's stuffed somewhere.
 
Did you use xcopy or explorer? Do you know the firewire-ata chip? Oxford is
good.

You should get 10-30MB/s, depending on file size. That's 60-20 mins. I wonder
if write cache is disabled.

You got that utterly mangled. 400Mbps is around 40MB/s.

Yes, 1.6 MB/s is excessively slow.
