Thanks for your answer, I'll investigate the USB resets. Still, it seems strange that the rebuild only started five hours after the reset. Is this normal? The reason I said the resets don't seem to hurt is that I also get them for a second disk (not in a raid), and file transfers aren't interrupted, I haven't (yet?) seen any data corruption, and other than the message, the kernel doesn't seem to mind at all. BTW, this time, badblocks ran through without any errors. The only strange thing remaining is the rebuild.
