I have hit and miss issues with USB at times as well. I ordered a sata external enclosure that has a fan for cooling as well. Some external enclosures have both sata and USB ports. That way you can use sata when possible. I ordered three USB enclosures and only one works well. The others either don't work at all or are very slow. I might add, I've read where people who make their own external drives, buy the drive and enclosure separately then assemble it themselves, put the drive into their computer to format with a file system and then put it in the enclosure for normal use. Some think it formats better hooked directly to a sata port inside the puter than it does over USB. I'm not so sure myself. In my experience, if it works well, it works well all the way around. May buy me a card that has both internal and external ports later on. Sale maybe?? Dale :-) :-)
