When I attempt to mount a .dmg file, I get a message "The following Disk Images failed to Mount" and below it "Function not Implemented".
Does anyone have any ideas as to what might cause this and how I might fix said problem?
Thanks.

My iBook had that problem about 6 months ago. I tried everything I could think of to fix it, but it wasn't cured till the next Panther update (I forget the number), which fortunately came only 3 or 4 weeks later. So you might try updating to the latest version of the system software if you haven't already.

Try using Disk Utility to mount them.

1. If you are running Mac OS X 10.3.1 or earlier, update to Mac OS X 10.3.2 or later.

2. If you're having problems mounting

- disk images;
- external drives, e.g. FireWire drives or iPods;
- CDs or DVDs;

after installing the Mac OS X 10.3.4 Update or later, try the steps in this Mac OS X Hints article.

Explanation: What seems to be happening during Software Update on some Macs is that kextcaches (Kernel Extensions caches) are not being rebuilt with the latest versions of kernel components as part of the Update process. The steps in the Mac OS X Hints tip have you delete the relevant files that should have been rebuilt. These are then automatically rebuilt, using the latest kernel components, when you restart the Mac. The first restart you perform after deleting those files takes a little longer than normal due to the rebuilding of the relevant files.
