So my macbook is acting up, and although it boots up it automatically freezes. The mac genius at my local apple store tried archive and installing but that did not work, and she wants to try an erase and install. I have most of my hard drive backed up but would like to back the rest of it up. I know that the hard drive is easily accessible by taking out the battery of the macbook. My question is whether I can simply take it out, buy an external casing, and plug that in to another macbook to back up my data. The Macbook is a 1st generation one and the hard drive is a 60 GB Toshiba. Any help and advice is appreciated!
