Thanks bob, I've got a lot to learn... Anyway, I only saw the SCSI bit as the device was listed twice in H/W detection (the other being /dev/hdc) when I was trying to get the thing to work. It seems that may be normal... I have since discovered that at times, /dev/hdc looses it's interrupt - sounds a pretty clumsy thing to do - and its not clear whether something called devfs is to blame or not...Jon
