MicroSoft SQL Server, Error: 3241 using MS SQL 2008 enterprise version

Hi All,

Several weeks ago I created a compressed back up in ms sql 2008 enterprise version.  I am trying to experiment with the Restore capability and getting the BELOW error.  I am trying to restore the database using the Restore Database GUI.

The database size was 250GB and after creating the backup it became 104GB. I selected the database From a Device option. I created this backup on Windows 2008 and copied that file into my Vista Ultimate computer and trying to restore at that computer.

When I go to the actual server to restore the database it seems it picks up the right database without getting any error. But I don't want to take any chance and I want to test this backup in a different computer, with ms sql 2008?

What Am I missing?

The media family on device 'I:\HumanFinders\Drive_E\SQL_Backup\HumanFind\HumanFind_20090321' is incorrectly formed. SQL Server cannot process this media family.
RESTORE HEADERONLY is terminating abnormally. (.Net SqlClient Data Provider)

Thanks,
