I have the same problem you have addressed in a previous thread. You said that one could take the external drive apart and connect it directly to the computer, but any data should be backed up first. How do I do that if I can't access my external drive? I do have information I really don't want to lose on it. This drive doesn't show up under the listing of disk drives on my computer, but does show up under Disk Management. But there seems no way to get into it.
