I can see that some users might feel more > comfortable with this behaviour. Yes, if only because it saves power and reduces noise (for USB-attached mechanical drives at least). Note that this also requires logic in the enclosure to cut power to the drive when the device is detached; not all enclosures do this. Brand name drives (Maxtor OneTouch, Western Digital Passport etc.) usually do, while cheap DIY enclosures usually don't. DES --=20 Dag-Erling Sm=C3=B8rgrav - des@des.no
