hi,i just recoeved a pismo (powerbook g3 w/firewire). There seems tobe something wrong with the internal hard drive. When i boot it up, i get a blank screen, but when i unplug the internal hard drive, then the flashin question mark appears on screen. The internal hard drive never spins up, but i know it is a good hard drive because i booted from it from firewire. I have tried many drives, whatcould prohibit the drive from not spinning upat all?
