I am helping a friend to recover data from an internal hd taken out from a 2011 macbook pro. A new internal hd has been installed to replace the old one(The old one actually worked fine according to him. But somebody in a computer repair shop told him it was going to fail soon). But my friend, who is not savvy in working with computers, didn't backup the system correctly and has never swapped disks before. What I suggested him to do is to put the old internal hd into an external enclosure, boot from the external hd to do a system backup, then finally restore it to the new hd. Will that work as I described? Thanks for any advice.
