Serious Disk Image Bug in Mac OS X 10.4.0 

Dave Nanian at Shirt Pocket has found a serious bug in Tiger:

We’ve just reproduced a bug in Tiger’s image handling that any SuperDuper! users should be aware of.

Basically, if you create a sparse image in Tiger and back up to it, everything is fine. You can unmount it, and the file size is as you’d expect.

If, however, the image is larger than about 1GB and you try to mount it, Tiger will destroy it, and set its size to 1008MB.

I cannot recommend that you rely on any application, including SuperDuper!, that uses images until this Tiger bug is fixed.
