I purchased a recommended hard drive (Western Digital WDBABT0010HBK-NESN) and hooked it up with the SATA cable to my Motorola 7232 DVR. I selected Enable More Storage, activated the extender option, and re-booted the DVR. The external drive is on but the DVR does not show it. Under DVR/Recorder Status it just says DVR Usage and Capacity and does not show Local Drive/External Drive. I've rebooted the DVR and unplugged/plugged in the DVR about 5 times now and still nothing. Any ideas on how to get this working? The light on the external HDD is on and the drive is running.
