MyBook I TB: Light On but Not Oscillating; No Data Access

My Book World Edition 1 TB. (White). The light in front come on. I hear a “scritching” sound. But the light doesn’t move up and down like it used to and I cannot find the device on my network. I suspect the drive itself has locked.

I tried disconnecting it, then holding the reset button for a minute while powering it up but that did nothing. Same thing.

I’m not technical. Is there any hope?
