Help me out?? magnets on a camera bag...

Does this matter with modern gear?

I am looking at a Tenba DNA 15 but I have no clue about the magnet issue except to keep a spin hard drive away from it..

I haven't experienced any issues with small magnet closures on bags. I sometimes carry backup spinning hard drives and film. Others my have different experiences though. I did look up reviews on the DNA and no review I found mentioned it as being problematic.

I wouldn't even worry too much about hard drives. Every drive contains two very strong magnets which obviously don't cause any harm.

Unless they are some kind of crazy rare earth magnet I wouldn't worry. They shouldnt be strong enough to mess with it. Theyd probably keep them weak enough not to strip magnetic card data and itll require more than that to mess with drives.

I would not worry about anything that was within a metal (conductive) box, like the platters of a HDD. Magnetic and electric fields cannot penetrate them. This is based on the principal of the Faraday cage. If you look at Civil Defence information from the cold war period they used to recommend keeping a transistor radio in a metal box, so that you could listen for the emergency broadcasts in the event of a nuclear attack. The box, acting as a Faraday cage would protect the electronics of the radio from the nuclear bombs Electromagnetic Pulse or EMP.

In an ideal world this is probably true. But I had a coworker pack up some gear of mine that included an IBM laptop and about a dozen very strong magnets (100# pull) used to mount instrumentation on machinery. The magnets were placed in a metal box which had been tested to meet FAA requirements on transporting magnets in aircraft. This box was in close proximity to the laptop. When the gear arrived at my office the hard drive in the PC was hosed. It could have been a coincidence but I often wondered if the strength and number of magnets could have been the issue.

Good article at http://www.pcworld.com​/article/116572/articl​e.html that supports what Al says.

Interesting story, but a spinning hard drive != modern gear.

Let me know when you have another way to store 2 TB in your pocket for under $100.

Convenient and cheap doesn't make it "modern".

mod·ern

adjective

1. of or relating to the present or recent times as opposed to the remote past.
"the pace of modern life"


So a product that is still being actively developed, manufactured, and sold in the millions today isn't modern. OK.

You win Mike.

Thanks for the help..
