So I updated my OpenFiler storage appliance a few days ago and I had to restart it for the first time since the update. To my surprise upon reboot, I got the following “non-error” message “GRUB_”. No other message or error code.( OpenFiler does not have a LiveCD ) I searched all over google only to find out that most people said this was some sort of error that required a LiveCD to reinstall GRUB. Well, I decided to hit the F11 key on restart ( to get the list of available devices to boot from ). Upon manually selecting the correct HD, I was able to boot. The moral of the story is, make sure your computer is attempting to boot the correct hard disk. I went into the BIOS and set that hard disk as the default boot device. Works just fine now.
Cheers,

P.S. On another topic, the error “Comreset Failed (errno=-16)” has the good possibility of meaning the power for that drive has failed and to try another molex connector ( I just found out two connectors, in one chain of the power supply, just failed on me ). If it isn’t the power source ( you can tell the drive is spinning ) then its either a bug or the drive itself is causing a problem. Check SMART status.
