I used super duper to copy all files from a disc I was replacing to a new larger disc. Once I checked that I could boot from the new disc and all the applications where functioning I replaced the old disc with another new disc to be used to back up my new main boot/working disc.

I'm having just one problem. Permissions on the disc I am now working as my working disc are read only and I can't change them. I'm having to enter my admin password to copy anything to the disc and can't unzip files. How can I change permissions on my new boot drive?
