I have a usb-attached HD that I use from time to time. When it's connected
to my desktop through a hub it works flawlessly. When connected to my Dell
D600 Laptop, however, it sometimes randomly exhibits a loud click (as if the
heads went berzerk) and the device goes unrecognized (i.e. the USB layer drops
the device and then redetects it again; meanwhile there is FS corruption.)
The same behavior happens with 2.4.x and 2.6.x
In /var/log/messages I see something like:
hub 3-0:1.0: over-current change on port 1
hub 1-0:1.0: over-current change on port 3
...
usb 1-3: USB disconnect, address 2
usb 1-3: new high speed USB device using ehci_hcd and address 3
...
usb-storage: device found at 3
usb-storage: waiting for device to settle before scanning
This doesn't seem too good.
Here's the complete passage from /var/log/messages:

Any chances someone has seen this before or if there's something I can do
to stop this from happening anymore?
