Okay, so I'm a new rider. I wanna commute to work and take my Powerbook with me in a tank bag, but there is a hell of a lot of folklore out there about Magnetic tank bags and hard drives, and the magnetic fields disrupting the data on a computer's hard drive (which is essentially magnetic 1's and 0's).
I'm not inclined to believe that this is really a problem, but am just checking with the more experienced among us. I found this informative post here:
"I can state unequivocally, as a professional computer geek for the last 12 years, that a magnetic tank bag poses no significant risk for your laptop.
The LCD monitor of a laptop is magnetcally insensitive - so no problems there. The hard drive, while being a magnetic device, is actually quite resilient to your average magnetic field. It requires a very strong magnetic field to damage the data on a hard drive - tank magnets are strong but not that strong. Magnetic field strentgh drops off as the inverse cube of the distance from the magnet (for those who don't speak Geek, that means that the power of the magnetic field drops very rapidly as you get farther from the magnet) so as long as you aren't placing the tank bag magnets directly onto the hard drive they pose no risk. In your average laptop the closest the the tank magnets could get to the drive is a 1/4 inch or so...plenty far enough away to pose no threat. By the time you throw a bit of foam padding in there to isolate potholes and vibration, which are a real threat, your laptop won't even know the magnets are there.
It should be noted that this does not hold true for 3.5" Floppy disks... they are far more susceptible to magnetic damage and tank magnets are more than sufficient to do the job - even with a 1/2 inch of foam in the way."
Is anyone in a position to, through experience, fully confirm or disconfirm the above statement? This must have been discussed before but I can't find the discussion via search. There's lots of disinformation in both directions on google...
