Failed Firmware update for MyBook Essentials 3TB

I tried to do a firmware update for MyBook Essentials 3TB drive. The screen showed update in progress and remained in that mode for about 3 hours or so. The entire computer hung after that and I had no choice but to reboot. After rebooting, my computer does not detect the MyBook at all.

Any help, suggestion or advice would be appreciated.

SVEER,

This is most unfortunate, however, it may still be possible to proceed with the update (And correct functionality issues with the device) if you are to try a second time. Even if you are unable to detect your unit in your system, the firmware update utility may be able to do so.
