My internal hard drive failed in my iMac about 3 weeks ago. After several attempts trying to repair the disk, I had a new one installed. I then tried to recover the data on the old hard drive (most items, all of the important ones, were backed up). I put the old hard drive into an external hard drive enclosure and have access to the files. The problem is I don't have rights to save or move some of the files I would like to copy to the new internal hard drive. I tried disk utility to repair the old hard drive, but get a an error (after verifying it says I have to repair it, try to repair and it says I have an error and to back up the files I can and reformat). I believe part of the hard drive is damaged. Is there anyway I can change the rights on the old file so I can save it?
