I've recently received an old media storage device from my father that connects via eSATA. To use it with my computer, I bought an eSATA to USB adapter. The device powers on when I connect it with the new cable and power cord. However, I'm having trouble getting my PC to recognize it. I only receive a notification when I unplug it, saying that the USB device went away. I'd love to know how to check all my USB connections and ensure this device is recognized so I can set it up as a new storage drive, since it holds around 1TB of data. Any tips would be greatly appreciated!

If you ran `lsusb` and the device shows up, that’s a good sign! Your output indicates that it’s recognized. Now you just need to mount it. If you’re unsure how to do that, let me know what operating system you’re using, and I can help you get it set up as a storage device.
You should use the `lsusb` command while the drive is plugged in to see if your computer recognizes it. Sometimes, the order in which you connect the power and USB cable can matter, so you might want to experiment with plugging in the power first, then the USB, or vice versa. This can help if the drive goes idle and doesn't recognize the connection properly.
It sounds like the drive might not be getting enough power. A lot of these adapters can have a secondary power connection; if yours does, try using that. If not, make sure you're plugging it into a high-power USB port and consider disconnecting other USB devices to free up power, because they can share the USB bus and drain available juice.
