How to checksum for a DVD under Panther? I'm helping a friend checking if a DVD was burned properly but he's saying that  under Panther there's no Images menu in Disk Utility.
It looks like Panther's hdiutil supports checksumming, even if the Disk Utility GUI might not:

hdiutil checksum myimage.dmg -type MD5


(The supported types of checksums are listed in the man page. A common one seems to be UDIF-CRC32. If you use UDIF-CRC32 or UDIF-MD5 the checksums will be calculated separately per partition.)

Or you could always simply use the md5 command:

md5 myimage.dmg
