TempDB Files Gone Missing

I was in the process of migrating a server from one physical box to another. They are identical drive setups, same OS (2003), same SQL install (2005). Our server team did a 'PlateSpin', which copies the drives from one server to another, as long as the files are not in use. I did not reinstall SQL on the new box, i let the 'PlateSpin' tool copy everything over for me. I then stopped the SQL services on the old server and new server and copied over all of the system database (.mdf & .ldf) files. As soon as i started up the services on the new server, it looked great with one exception. The TempDB was only showing one datafile. When i queried sys.master_files, it was showing me 8 TempDB files. I tried restarting the services, but i still saw the same, only 1 file. I then tried to re-add TempDB files with the same name, but it would error saying they already existed. In turn, i could add new files with different names and they showed up fine. However, on a restart, they would not show up in the properties of the TempDB.

When i queried, sys.master_files again, i now had 16 Temp db files listed in the results. I deleted all but the original single file that was recognized out of the sys.master_files table and re-added the additional 7 files with he original names, restarted the service and then they all appeared.
