I've a quite long experience with unix systems and my precedent NAS was a Linksys NLSU2 with Debian Etch (only 32Mb of RAM). > > Lenny on the TS 109 Pro II works well expect the known missing support for the DMA on the disks (I'm waiting the new updates on the Debian kernel). I have a nasty problem: I'm trying to use the internal SATA WD disk jointly with an external USB disk (WD MyBook 500Gb): I would configure a RAID1. The system is already installed and working on the internal disk but when I try to add the external one to the RAID /dev/md0 it starts the sync process but it fails after several minutes under heavy work. The usb device resets and the unit is excluded from the raid. I've changed 3 different USB cables and the drive works well with the old NAS (USB 2) and with my PC. I looks a problem with the orion-ehci module. > > It is strange that the problem appears only under the RAID1 sync: I've tried to heavily stress the external drive with other procedures, like 'md5sum /dev/sdc' or 'dd if=/dev/sdc of=/dev/null bs=50M' and so on, but the reset of the drive doesn't happen. > > > > Can you help me?

What is the 2-1 hub device? Whatever it is, it appears to be the source of your problems.
