After modprobing the needed modules (ehci-hcd and usb-storage), I mounted the disks (no error, as expected) and did the following : - Copied about 12 Go of datas from lacie1 to lacieroot (at at least 20Mo/s, so it didn't take long) - Made an md5sum for all the copied files at the same time on lacie1 and lacieroot. The resulting sums were exactly the same. So if it doesn't look like a successful test, I don't know what does. > I don't know why.
