Magnetic?... well perhaps. Or maybe just lots and lots of bytes of data going to and fro. Everything has a life expectancy and failure will fall somewhere within the bell curve for it. PC drives just seem to fail very early in the curve for me both at home and at the office. About my best photographs... I hope they will last long enough that my children and grandchildren are able to enjoy some of them. I'll bet you do too. Bob
So will we, one day. When that happens, what difference will it make if our precious photos (aren't they all precious, btw?) "vaporize" on our hard drives or get tossed out along with the old shoebox by our descendants?
Well, then, there's your solution - switch to Mac!
