Try a USB Y-cable. This picks up power from two USB ports.
USB 2.0 ports are current limited to 500mA whereas 2.5" drives typically draw 900mA during spin-up.
thanks, that is the only thing i havent tried. this unit is a usb3 version with the changeable interface Seagate put out on this model. i can not get anywhere with it. brand new it had trouble with the 18" supplied usb 3 cable. i had to buy a new one , as a last resort, to make it work. i never thought that would fix it at the time, but did.
actually, i think the thing is shot, those beeps i can hear when i put my ear up to the case when i put power to it sounded ominous. cant count the number, but more than 3 or 4, i am sure of that. I tried to count them but they move along fast and barely audible without putting my ear to the thing.
it is/was a handy thing but did not take any abuse, never moved farther than from one room to another just to transfer or add without needing to keep 2 or 3 computers on at the same time. i do not need it, got if for doing a product review on it when it came out. so, never had any warranty with it. only put movies on it since it started off with such a shaky beginning. but, after a year of ok performance, i did begin to trust it more, and did use it to watch videos. oh , well
thanks
