I have just installed (attached) a Maxtor 250Gb USB HD to my son's Imac G4 (OSX) for back-ups etc. We tried to copy a large music file (11.5Gb) and it says it needs around 5 hours to copy. This seems extraordinarily long.

Can anyone suggest why this might be please?

Is the HDD USB 2 and is the USB port on the iMac USB 2?

IIRC, the USB ports on the G4 iMacs are all USB 1.1. That is your problem, USB 1 is SLOW, should have gone with FireWire...

The Firewire connections on the iMac are 4 pin, whereas the USB disc/cable is 6 pin.

Yes G4 iMacs are USB 1.1 which will be very slow. A firewire drive would be a much better option (and in general is a better option regardless for an external drive).

i am going to hop on the bandwagon here saying that usb1.1 can be quite slow, sometimes even 2 can be slow and firewire will always be the fastest. for a little comparison, a 512MB usb jumpdrive may seem pretty fast to most people no matter what usb 1 or 2 because you are mainly transfering word documents and small files

see if you can return the drive and pick up a firewire one.

What Schweb and Coach said is very true. USB 1.1 is DOG slow and you are trying to copy an almost 12GB file. I checked and Maxtor also makes your drive with both a USB 2.0 and Firewire 400 interface. If you can, take back that USB only drive and get the Dual interface model. It will fly.

Uh, no. ALL recent Macs still have the 6 pin FW ports on them for FW 400, and I can guarantee your iMac has one if not two. No Mac has been made with the 4 Pin connector, that was a PC only thing. It's a different connector than USB and the two are not compatible.
