darkredbbb wroteI think you're right. I'm still using USB and both FW800 look like the ones that got damaged. I'll look into taking the drive to a technician to fix the adapters.
Actually, I recommend you fix it yourself.
By the way, both FireWire ports are not working because it is most probably a FireWire port multiplier that is used after the SATA to FireWire adapter. Thus, when that adapter is broken, the multiplier is disconnected.
