[qanda]This question is published in the hardware section for the Sony RDR-HX910. Click here to view full specs.[/qanda]I really like this recorder but the internal hard drive died. I have another 160gig ATA drive that will work but I have no idea how to format or prepare the replacement drive. Does anyone know how to force the machine to prepare a new hard drive?
