Does it matter which USB port the device is plugged into? USB0-4?

So if it is a USB-HDD, what should be on the MBR?
So, I think I've really screwed up my device, putting MBR's on it,
formatting it ext3, etc. etc. I want to start with a blank slate (and
of course I didn't dd the original image off of it). Should I
reinitialize the device with a Win2k format command (FAT16) in order to
work with syslinux? What about the MBR, should it be zeroed out?
