There is a monitor programme in the Utilities folder (I forget the name but it is self explanatory, sadly I am away from home and stuck with a pc) Open it, select the disc activity box and the read and write speed of any disc activity will be shown. Just copy a file of reasonable size to or from your firewire 800 drive with and without the firewire 400 bits connected, and see if there is a different read and write speed. My firewire 800 HD runs at around 60 whatnots per thingy on reasonable sized files (I forget the exact units). :-) Frank --- Steve Unsworth <lug@steveunsworth.co.uk> wrote: > I have a totally off topic question. > > I've just moved from an XP desktop to a 24" iMac. > This has a Firewire 800 > interface - something my old desktop didn't. > > So I've connected an external hard drive with > Firewire 800 interface to the > Firewire 800 port on the iMac.
