I plugged in my external HD last night and was told I'd have to format. I moved all my data over to a larger disk during the night so as to clear it for this. I woke up this morning, did a spotlight search for Time Machine and got "An unexpected error occurred (Error Code -43). I then, in my half asleep state, thought that I'd just uninstall TM. I have this app called AppDelete, which did the trick. Now I realise that TM is in system prefs and appears to be working. Firstly, has anyone else gotten this error, and secondly, is there any way to get back whatever it was I deleted earlier? Maybe by using the install disk. I looked at it earlier and didn't see any options. I noticed that the TM "app" in the Applications folder was only a few hundred kbs so I may not have done much damage. Doesn't anyone know what that part is? Is it just a frontend or what?
