Likewise the cables.
Good thinking would be, but as I mentioned before, I tested this issue on several hardware. With 2 new disks, new enclosures (3 kinds but same type), on different kind of servers and with different USB cables. I think it must be the software causing this. Especially because the same hardware setup worked fine for long on Debian 6. That's why I turned to the SL mailing list. So disk is ok, cable end enclosure is ok, and server hw must be too I believe.
