Using my PC to view the HD from old Mac, please help

A good friend asked me if we could get all of her music and saved files from this old Powermac G4 1914c and I figured it wouldn't be that difficult.

I plugged in the old edi HD into a Dell PC and couldn;t find the drive at first. Then downloaded Macdrive 9 with a 5 day free trial. Presto! I could view the files but I'm not finding much.

Now I'm not a mac user so it's probably my lack of knowledge but can you guys/gals point me in the right direction?

I looked throughout almost all files it seems and only found a few clusters of pics. There has to be more and I have not found any music. Looked in the obvious places and some but it seems like I'm not accessing everything....

Please help?
