Ibook resurrection with firewire cord (is there a usb2.0 alternative?)

trying to get my sisters ibook back from the spinning gray wheel of death, apparently i can do a firewire target disk boot sitchnerio from my computer and possibly fix the disk, but I don’t have a firewire cord - is there a usb 2.0 alternative to this maneuver .

I have a firewire cable if you wish to borrow one.

Send me a PM if you need help with this – we have firewire cables as well. 

good to see people helping people!
