I'm planning on picking up a 3.5" drive encosure and a 300G disk tomorrow. To my horror a number of sites have 250G limits on their drive encosures. What is the reason for the limit?

255 - hex errors, etc.
close to same reason you can only have 254 usb devices connected.

>>2 You are kidding, right? USB has a 254 device limit because it only uses 8-bit device ids. 250G has nothing to do with this.

The limitation is probably to do with the drive controller within the enclosure itself. Remember, USB doesn't have hardware explicitly for controlling hard drives (in the way that IDE does), it's just a bus for data. If the enclosure's controller can't address anything beyond 250Gb, there's probably not much you can do about it (unless the manufacturer offers a fix in the form of a firmware upgrade).

i know that the dynex one i picked up at my BB (i work there) has support for up to 500gb drives, its alittle bit less expensive than the adaptec one we sell too
