It depends on what you have on the drive. If its important stuff then you’ll need to get it working as you can’t access the drive any other way than through the TC (uses its own custom OS and file system). If you don’t care about the data then you can at least reuse the drive after formatting it as needed for the OS you plan to use on it.
After mine failed I jumped to a Mac mini as my backup system. At least then if it died I could still gain access to the data on the drives.
