Folks, im having issues with random reboots. few days ago, it woudnt boot at all, just cycled through the reboot.... thought it was toast. i left it off for a few days and today its booted up. i have a roamio pro 6 tuner dvr. i think the drive is going bad here, based on all the other threads i've read.... and now since it looks like its not completely dead i will get it replaced ASAP. the question i have is what are the recommended/proven drives to use? thanks!
