I looked at the list of mailing lists and none of them seemed appropriate, so if someone can point me to a better resource, many thanks. I'll include the problem, in case anyone knows that's going on.

I've had a similar problem to this in the past, with a different computer, product and company, so it must not be super rare, but I can't find anything relevant googling.

I have a self created DMG file that fails to mount on four different people's computers, the Finder reporting "Illegal seek". It mounts just fine on about a dozen other machines, including the exact same model and system version. For example, two iMac 24" with 10.5.4, mounts fine on one, fails on the other. Repeated downloads of the DMG don't result in valid files, and if I just copy the DMG across the network to one of the computers, it still fails.

Mounting and verifying both the Master and Final DMG in Disk Utility results in no errors. I have "Verify Checksums" turned on in Disk Utility preferences. The Master is 40MB, the Final, around 7MB.

Our distribution process is thus:

1) I have a "Master DMG" which I mount, copy a new build to, then unmount 2) I load the "Master DMG" in Disk Utility, click the Convert button, select Format: "compressed" and Encryption: "none", and create the smaller DMG 3) This is then uploaded, with Transmit, to a server. Everyone but me downloads it with FTP from this server

Any insights or pointers to diagnostics or other information sources would be very well appreciated.

Thanks!
