Mac file transfer speed

[Bigtwin]

Plugged in my new seagate 250mb drive - seemed fine to do a plug-n-play type thing, all seemed dandy. It's a USB2 interface. Didn't format the drive, as it seemed fine.

But - takes an age to transfer data. Wondering if it's doing some extra conversion somewhere, and if I should have Mac formatted the drive before I started.

Any ideas? Cheers all.

Most Macs, as std, only have USB 1....

check if it's high speed in the about this mac system profiler tool.

Even at high speed, it takes a good old while to move many GB of data.

Older macs (G3, G4) have USB1 (11Mbps = slow) newer (later G4, G5, Intel) have USB2 (480Bbps = ok). Prefer the uber-mighty firewire if the external device has it.

Can't see anything in Profiler that tells me whether it's USB 1 or 2 - how do I tell?

This is a "later" G4 - i.e. with DVD-RW, if that helps.

Seagate doesn't do firewire, ony USB

You have OS10.2 or 10.3 then? OS10.4 says on System Profiler wether it's USB or USB High Speed Bus.

No 10.4.6, but under USB in system profiler it doesn't say:=

PCI Device ID: 0x0026
PCI Revision ID: 0x0000
