Well I tried very hard to get my lacie 500 gig to work with my f900, but to no avail. I tried the fat32formatter and thanks by the way, but that didnt work either. So I just had a question to the guys that power their drives in the car. Can put a full description of what you have because most likely not all drives will work with the F series. Also a question to boris, does u r hardrive come with some sort of split usb cable where u can plug into a car invertor for more power or do u do something else. I would be greatfull for this info cause I am trying to decide what kind of drive to buy and
