It may turn out that there is something wrong with this particular drive. However, try the following steps exactly in order:
1. Power off Camect and remove the drive. (Firmly press the power button for 1 second, wait up to 40 seconds, and pull the power if it doesn't power off.)
2. Remove the drive and format it to NTFS in another computer. Don't reconnect it to Camect yet.
3. Power on Camect and confirm that the drive is not showing in the disks tab.
4. Power off Camect again, plug in the drive, and power back on.
5. Confirm that the drive is showing in the storage tab, but requires a format.
6. Use the eraser icon from the storage tab to format it.
7. Wait at least 10 minutes to ensure the format had enough time to complete.
If it's not showing as in use at the end of that, open the home settings and use "Report Bug" so that we can see what happened. Check the checkboxes to include logs and settings from the device.
