I made a halo backup cd. I used an Acer DVD drive to make the cd image (using alcohol 120%) in Securerom 2 (image made at 4x, burned at 4x onto office depot 52x CD-R) It worked. Now i am trying to use it on my other computer which has a samsung sw-216 CR-RW drive on it. Everytime I insert the CD, it says "please eject and re-insert the Halo cd-rom select ok and restart application". Can anyone help me? I think it's because this crappy drive can't run backups. I have already updated it with the driver.
