is it possible to salvage data from a Mac disc?

i've been trying to salvage some files from a Mac iBook that died and I cant seem get it to work, I have the drive in an external enclosure and linux can see it, with linux mint i can even see the 'read only files' in the user directory, but i can't copy them or save them in anyway

i tried this code "sudo chown -R username:usergroup /media/drivename"

but i keep getting read only messages, even though i seems to change ownership, when i check the permissions, the files are still owned by the previous root or username of that HDD

is there anything I can do to get my pictures and documents out?????

I usually work from the command line. I think I noticed that through a GUI, what you describe happens when you are dealing with a mounted mac filesystem and are not root.

What happens if you try this:

sudo -s
cp -vR /mountedMACFilesystem/home/* /target 1>filelist 2>fileerrors

...where the source and target destinations are modified as appropriate. That will copy all the files in the home folder and make a list of each file that was copied as well as another list of read-errors.

You can monitor the progress in another terminal with

tail -f filelist
