Quartz Extreme said:At the beginning of a disk image file is the sum of all the bits in that file. The program will then checksum to see if the sum is what is really in the image. If it is off, it reports "invalid checksum"
If you downloaded it from a website, it likely was corrupted during download, and I would suggest trying to download it again. If you downloaded it from a peer to peer network, the file may be a fake.
