PettyOfficer, you make a fair point above:
Why, indeed?
My enjoyment of music certainly has little to do with yours, PettyOfficer, though as a friend I would love to see you have more of what you like.
The only reason I'm weighing in here is for the benefit of posterity, and for the hearts and minds of other posters. This is what I do, and it's not meant as a slight to you, or an incitement to you to change your ways. I just don't want future generations to look back at us arguing about formats and misunderstand any perspective.
So, to that end, I have two more points I'd like to bring up. You continually mention cassettes and solar flares, and I think a fuller understanding of the issue would bring clarity to the discussion.
1) Magnets have a measurable strength, as anyone who's ever tried to push two together with their polarity opposed will tell you. Some are more powerful than others. The strength of a magnet's "Magnetizing Field" is measured in Oersted (or Oe) units.
Any storage medium for magnetic information, including cassette tapes, reel-to-reel, and platter Hard Disc Drives (NOT Solid State Drives) also use magnets, and due to the unique principles of magnetism it will resist having its field altered or realigned, to a certain point. This property is called "coercivity", and it's what protects your data. In a very simple sense, a weaker magnet cannot influence a stronger one. One cassette tape cannot erase another, nor can a weaker magnet erase a hard drive.
The Earth itself has a magnetic field of 3-5 Oe. The magnetic field generated by a cassette tape is between 25-50 Oe. Modern hard drives, which write data in a perpendicular fashion, have an Oersted rating of 4000-5000 Oe.
By contrast, the magnetic read head of an MRI (magnetic resonance imaging) machine in a hospital has a rating of about 60,000 Oe. Not to worry, though: a magnetic field degrades exponentially over distance. As long as your hard drive is more than 1 meter away from the MRI read head (i.e. not in the MRI machine itself) the field will not be strong enough to effect your drive.
I hope that puts to rest the question of whether "giant" magnets will erase your drive, and the comparisons between cassettes and Hard drives. Hard drives are literally upwards of 100 times more powerful than cassettes, and the strongest magnet most of us are likely to encounter in our lives won't erase them unless we're trying. Nothing to worry about.
2) Solar Flares. I'm not sure where this concern comes from, but it's not warranted. Solar Flares wreak all kinds of damage on our lives, degrading satellite orbits, ionizing our outer atmosphere, corrupting radio communications, and numerous other detrimental effects. One thing they don't do is effect the Earth's magnetic field. If they did, you would routinely have bits of metal around your house flying into the air.
The single most magnetically disastrous entity in the known Universe is a magnetar. This is a superdense neuron star, so dense that a thimblefull of magnetar would weigh upwards of 100 million tons. It's the strongest magnet in the universe by a country mile, and it will literally rip the water out of your body at 1000 km. It's magnetic field is hundreds of billions of times more powerful than the sun.
However, it couldn't even erase credit card strips until it's about half the distance from the moon away from Earth. By that point, the gamma radiation it emits will have destroyed our entire civilization.
None of the problems from solar flares are magnetic. They will never erase nor corrupt your hard drive.
Plenty of things can erase or corrupt the data on a hard drive, but magnetism and solar flares are not among them. You're far more likely to lose data to a power failure, read error, or any other of 100 things than you are to magnets, and you can easily protect against those things.
So be concerned about choice and about quality, but don't worry about magnets or solar flares. This data will outlive us all.
Why does everyone here complain more (numerically) than I do, if you already have what you want? Why aren't you happy? Why waste your time here?
