GPS can go offline. If you’re handy enough to navigate from the stars, I trust that method much more than a gps service.

I bought a seagate once. Brand new. 250gb back in the days when that was a lot.

Brand new, put it into my computer, turn on my computer. It sees it just fine.

30 minutes later, my PC started reporting errors.

Dead. Seagate would not honor the warrenty. That was 2003. I’ve yet to buy another Seagate since.

I assume your drives are dead, just based on it being Seagate.
