I've had some issues with them being picky about USB ports and cords, apparently not getting quite enough power to work reliably. Problem is a soldered USB interface and proprietary innards. I prefer having a removable SATA drive inside an enclosure, like this 1.5 TB for $90
. Gives you more flexibility for future use, too.
sorry to hear that. I DJ I am constantly unplugging and plugging them and have never had any problem other than running out of space because I store all my music on them and then I just upgrade hence my post.
