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.
You maybe able to skip the check sum at your own risk:
Checksums are there to protect you.
To enable skipping of the checksum verification to speed up mounting. So use the following (in Terminal):
*defaults write com.apple.frameworks.diskimages skip-verify true*
This will turn off disk image verification system-wide, regardless of what client has requested the mount (e.g. Finder or Safari or Disk Utility or DiskImageMounter.app).

When a 'corrupt' disk image file really isn't corrupt Authored by: mantrid on Dec 12, '06 09:51:57AM I just checked on a computer running Panther, and it has 'bunzip2' installed as a part of the BSD.pkg - I think the BSD subsystem was included in the standard install and would normally have been installed unless explicitly excluded. Nov 08, 2019 PostgreSQL Invalid Page and Checksum Verification Failed. Every page is divided into four parts (header, free space, tuples, special space). Offsets for the divisions are stored as 16-bit numbers in the page header; the offsets should go in order.

When a 'corrupt' disk image file really isn't corrupt
I'll definitely keep this information in mind...
btw, it's 'hdiutil', not 'hdutil' (obviously just a typo, otherwise there wouldn't have been any output from the 'attach' or 'imageinfo' subcommands).

Not the same problem but this may help a few users out there. Once in a blue moon I will download a file which should be an installer, it could be any kind of file however, and when I click on it it usually opens in script editor.
Often this files are named like 'Worlds Greatest program 1' Changing them to 'Worlds Greatest program 1.0' will usually make the program work. Sometimes just adding any dot and number will work. You will be asked if you want to add the extension, just say yes. I don't know why this happens but the fix is easy.

What Does Invalid Checksum Mean
I just checked on a computer running Panther, and it has 'bunzip2' installed as a part of the BSD.pkg - I think the BSD subsystem was included in the standard install and would normally have been installed unless explicitly excluded. So if attempting to open a disk image in 10.3 gives a corrupt image error, use and if the output indicates 'bzip2 compressed data', then try something like to see if it can be converted to something that can be opened normally. I get some 'trailing garbage' error during the process, but the output file seems to work ok.

Some preliminary observations:
Disk images created directly using hdiutil create -format UDBZ don't bunzip properly.
Those converted to UDBZ (originally created using 'Disk Utility' or hdiutil without specifying a format) seem to work after bunzip2, but only using Panther's bunzip2 - Tiger's bunzip2 doesn't unzip them properly.
Anyone have any ideas to account for the differences in the UDBZ images created by the two methods, and the different behaviours of bunzip2 under 10.3 and 10.4?

Developers: When you do make a UDBZ image, put 'Requires OS X 10.4 or later' immediately under your download link/button. Leave no doubt as to the minimum requirement of your app.
