Why do I get ‘Error: The device is not ready’?
This error occurs if your torrent client is trying to access a drive that does not exist, or is missing. This most frequently occurs if a drive letter has changed, or if the data your torrent client is looking for is located in a removable drive that is no longer connected to your computer.
1. To resolve the issue, make sure the path your torrent client is trying to take is still existent on your computer. For example, make sure all torrent jobs don’t have the Save As field set to a directory on a non-existent drive letter. The same applies to the Directories preferences. If a torrent job is using a drive letter that no longer exists, make sure you set the download location for the job to a valid location.
2. Try to "Force Start" your torrents after checking the location
