large data transfer via USB 2.0 is painfully slow

I have a server running Win2k Advanced server. It has 8 gb of RAM and 2 Pentium IV 3.06 mhz processors.

It is connected to our storage server via fibre channel. There is a 3.2 terabyte partition on our storage server dedicated for this server.

We have received 2+ terabytes of .jpg on external USB 2.0 hard drives. Each hard drive is 250GB of which most is used.

The server has  USB 2.0 and I am using xcopy /E to move the data from the external hard to the dedicated partition via USB 2.0. The problem is, I kicked off the xcopy yesterday and as of now only 70 GB's have been transferred from one hard drive!

There are no errors in the event viewer. This is a serious problem since I have over 2 terabytes to transfer. That equates to 31 days of transfer time!


Any suggestions?

Are you running Windows 2000 Service Pack 4? THis is the first service pack which supported 2.0, it also usually required updated motherboard drivers etc., if the server is not up to date on service packs and drivers, it will most likely run at USB 1.1

Yes it is an up to date server. SP 4 and drivers are up to date. The external drives when connected register 2.0

it is an IBM 8676-22x

I had 2 inputs on front and I had 2 usb drives plugged in. Only one transferring though. I am digging right now to see if it is actually USB 2.0. I am thinking it is not. Although, I was under the impression it was when it registered a 2.0 device.

You should be able to tell if they are 2.0 by checking the device manager.

If they are listed as USB "Enhanced" then it's 2.0, otherwise it's 1.1
