Usb Port Test External Hard Drive Is Recognized Via Usb Ports But Not Firewire?

External hard drive is recognized via usb ports but not firewire? - usb port test

I want to get rid of my external hard drive. Some time ago I have used their FireWire ports, it stops appearing via FireWire, so I pull the USB cable and passed, and I had no problems. I would like to know if there any way to the FireWire ports, without testing a FireWire cable to buy again?
