Please excuse my forgetfulness. I just got FS 2004 and I remember something about the 4th disk not being able to be backed up. I hope this mental lapse will NEVER happen again (G).
A good start would be to download A-Ray scanner and find out what protection it uses then we can go from there http://www.aray-software.com/
LOL no worries.... i may seem a tad snappy but you'd be too after "dealing with" 200+ misposts a week .... (cries) lol To make a 1:1 backup of copy protected games (1) determine the type of protection present using a program called A-Ray Scanner (which can be obtained from http://www.aray-software.com/ ). (2) If the game is protected via SafeDisc2/3 then duplication is highly hardware dependent and to be able to properly make a backup, your burner needs to be classified as "2-sheep" (for information on this sheep rating and to see if your burner qualifies as 2-sheep, visit http://forums.afterdawn.com/thread_view.cfm/45121 ). If your burner is a 2-sheep burner then head on over to http://forums.afterdawn.com/thread_view.cfm/23699 for a step-by-step on backing up your game. If however your drive is a 1-sheeper, visit http://forums.afterdawn.com/thread_view.cfm/36444 for a workaround technique. (3) If your game is protected with SecurROM then, even though it is not nearly as hardware dependent as a SD2/3 backup, having a 2-sheep burner is very useful.
