Absolutely no error, no odd display on the command line. Thus I guess we can say the problem is solved so far. You guys are wizards, you save my (geeky :-) life. I would hug you if I could ! Also, realize that these openbricks can't have an IDE disk, and are sometimes sold with lacie disks, so that might help other people. What puzzles me is that a 2.6.8 kernel didn't exhibit this behaviour for the same disk on another machine (and thus another usb2 chipset, but as that wasn't the cause of the problem...) In conclusion, I think that the patches from usb-devel I had applied solved usb2 problems that had really happened (but now are solved), but some code change introduced scsi errors (hence the working 2.6.8 kernel I tell about above)... I don't really know, after all you're the experts.
