The hard drive is dying on my HR54. This is a pre-release engineering test model I don't believe is a lease unit. It's been giving me notifications of issues for some time, then it would just continue working. A simple reset didn't work. I had to disconnect the power for 12 hours to get it back to normal operation. Is there a menu option to format the drive? Does the drive have a SATA interface like current ones? If I remember right, you can just install a new drive and the reciever will take over and make it ready for use.
