I currently have my external hdd hooked up to my xbox to hold all of my games. I would also like to hook it up to my pc. Is there a splitter or something i can buy to split usb b type cable that is hooked to my external?
In other forums people suggest networking the drive. In my case that is not possible because I am not using two pcs, I am using a pc and an xbox 360.
You can buy a switch that switches one USB peripheral between two USB hosts. However I would think that switching a USB HDD would be somewhat dangerous. You would need to ensure that you had safely ejected the USB mass storage device before switching it over, in the same way that you would need to safely eject before unplugging the USB cable in a regular single host setup.
OTOH, if you wish to access the drive from both the PC and Xbox at the same time, then this would be even more dangerous. For example, what would happen if the PC were to delete a file that the Xbox was working with, or vice versa? What would happen if two PCs tried to update the same spreadsheet or document? To avoid such problems you would need a separate file server to manage the HDD and to process read/write commands from both hosts. That's what a NAS does, ie it has an embedded file server.
