I investigated this a little further. The external USB 2.0 enclosure does work perfectly when the usb 2.0 module (ehci-hcd) is unloaded and the hd is hence mounted as an USB 1.1 device When trying to use the ehci-usb module, the mentioned problems appear, in FC1 and in Knoppix. Gonna continue testing.
