TM, you saw it from review

, but I bought it and tried it

(and returned it). And always the same message: "USB overcurrent", in my laptop (toshiba M200) and my desktop. I think Plextor didn't build this model very well.
Now I´m happy

with a Freecom FS-50, which it is really a LiteON slim unit.
The only problem, you must keep the batteries charged.
