I’m a bit of a newbie & I just had my iMac HD die this morning and am functioning at the moment off a 2 year old back-up External HD. I am thinking that rather than spring for a new iMac and have to upgrade all my software (I’m running OS Tiger), that it would be cheaper and just as well to get 2 new WD External HDs and use one as a new Back-Up and use the other as my actual “new HD.”
Is this possible? What is the difference between a HD that is being used as an “external back-up” and an internal one? I had this happen 2 years ago, and the guy installed an internal Seagate 500MB HD (which cost $100), while he charged me $500-600 to do this and transfer the data. Then he had me go to Best Buy and get another $100 external 500MB HD to use as the backup (which is what I’m running off of this moment.) I do not see what the difference is between a $100 internal and a $100 external - it just seems like a racket to scare me into paying unnecessarily.
Am I wrong? Can my idea work?
Thanks in advance for your input & advice!
