Looking to purchase a new DVD Writer for the first time, I notice there are USB powered devices available which do not require an external adapter/power-supply. This may be sufficient for stuff that do not require oodles of power.
I'm concerned that the amount of power required to regularly burn a disc might cause the USB port itself to overheat at the least, and burn out at worst.
Hence the question ( forgive me if it is naive ) - Can frequently drawing large amounts of power through a USB device affect the reliability of the port?
