If I connect to my WD External Combo drive via USB, I can recognize the drive and any images I make in both Windows and when I boot from the Acronis Boot CD from PCDOS. If I connect via Firewire, I can only recognize the drive in Windows. when I boot from the Acronis Boot CD I made, from PCDOS, I get an error message when I try to access the WD combo drive. It tells me it can't reconize it. I've tried to get help from Acronis support at least twice and can't get an answer. Anyone here help me?
