Installesd.dmg Hdiutil Verify Failed Status

Hey all, Not sure if I'll get any help from here – Posted something similar in Apple/support and haven't been able to get the required info. Short story &. Jan 20, 2013 Hard disk corrupted, 'Disk Utility' failed to repair so I had to erase the hard disk and reinstall Mac OX Lion. I erased my 'Macintosh HD' with the zero writeover security option successfully, but I'm having problems reinstalling Mac OX Lion.

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).

When a 'corrupt' disk image file really isn't corrupt

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.

When a 'corrupt' disk image file really isn't corrupt

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.
