Check your pins. They bend easy, but a > mechanical pencil with no lead in it can help you with that. Interesting idea.

Seriously? I mean, I certainly don't mind trying it and it wouldn't be any harder than pulling the cable to check the pins, but what's your line of thinking here? > 6) Try a slower transfer rate. Last night I bumped it down from 40MB/s to 20MB/s, disabled tagged queueing (which the adapter had enabled by default), and moved it to a different power lead. So far so good, but 24 hours does not my confidence earn. Thanks for the tips! If it's still acting wonky, I'll work through them. -- Kirk Strauser
