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.

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-MD5 the checksums will be calculated separately per partition.)
Or you could always simply use the
Use hdiutil on the mounted drive:
hdiutil checksum /dev/disk1 -type UDIF-CRC32
The final calculated CRC appears at the bottom when the command completes running:
macbook:~ me$ hdiutil checksum /dev/disk1 -type UDIF-CRC32 Checksumming Driver Descriptor Map (DDM : 0)… Driver Descriptor Map (DDM : 0): calculated CRC32 $4F7D78B1 Checksumming Apple (Apple_partition_map : 1) Apple (Apple_partition_map : 1): calculated CRC32 $C4E22BED Checksumming disk image (Apple_HFS : 2) disk image (Apple_HFS : 2): calculated CRC32 $04805620 Checksumming (Apple_Free : 3)… (Apple_Free : 3): calculated CRC32 $00000000 calculated CRC32 $52BB898F
This final calculated CRC (
$52BB898F in the above example) is exactly the same as the one reported by Disk Utility:
You can use the
diskutil list command for assistance in finding out the mounted drive's name.
