Re: Power Surge On Hub Port - Please Help

The USB ports have a limited amount of current available. Disconnect devices
from other ports and retry the hard disk.

Hi,

Please could someone help?

I have an Acer TravelMate 800 laptop which has 4 USB ports.

I have a Western Digital Passport external hard disk (320GB) and
whenever I try to connect this device I see the following error:

"Power Surge on Hub Port. The USB Mass Storage device has exceeded the
power limits of its hub port."

The device never appears in 'My Computer'.

I am prompted to disconnect the device and then click on 'Reset'.

I can connect a USB mouse in to any one of the ports and it works
fine. I can also connect a Kingston Data Traveller pen drive (512MB)
in to any one of the drives and that also works fine. It is only this
Western Digital Passport external hard disk which causes this error.

Can anyone help? Can it be resolved?

Any ideas most gratefully accepted.
