Most likely. You also can't run smart test on them, unless you read the manual and jump through hoops. I have had 1 external hard drive enclosure that actually communicated properly and that did support SMART without hoops. I've had several others that didn't work easilly and I've never bothered to learn the SMART command options to try and make the others work. As usual there's an ideal way to implement drives over usb, and then there's the easy/lazy/incomplete way most of them actually work.
