I have recently acquired a new seagate hard drive. I formatted it the other day to FAT32, as I had my previous hard drive (the exact same model), and plugged it in to my TV. It worked fine. However today I attempted to plug it in to my computer again, to add some files and the computer now refuses to recognize it. It is not anywhere on my computer, not in disk management, and it is as if nothing is plugged in. No light on the hard drive either, although it spins up when initially plugged in. What can I do to fix this?
