My older mac recently kicked the bucket, and I decided to switch to linux on a newer laptop, My hard drive was fine, and I now use it as an external hard drive. The one problem though, is that I cannot access any of my files. I've tried getting permission and it says that I am not root, therefore I can't make any changes. What do I do?
Yes, access it via Terminal, to get sudo permissions type:
Or you could try and change the permission using the following command as an administrator account or your account, if it's the only account you set up.
The -R will take care of all the sub-directories while the 755 permission will give the OWNER full access, USER read and execute and OTHERS read and execute.
Read = 4, Write = 2, Execute = 1
Read (4) + Execute (1) = 5
Read (4) + Write (2) + Execute (1) = 7
These are applied to groups and there are 3 groups in the order OWNER followed by USER followed by OTHERS and hence 755
