I have bought a portable loudspeaker, the bose soundlink, remarkable for it's performance, due to the speaker's magnet size, according to the design team.

I carry that portable speaker in my backpack, along with multiple portable hard disks, and I was wondering if this can be harmful...

 

What do you think?

Yes?  I mean the loudspeaker's magnet is quite powerful, it will capture iron objects (such as nails) when close to it

Can you clarify why it shouldn't alter data on the disk?

If you have nails sticking to your speakers then something is wrong.

Why? Isn't iron attracted by a magnet?

Yes, but unless the case of the speaker is a magnet, the tiny one inside isn't going to bother your HDD.

You'd need a magnet the size of a fridge to case damage. No worries with your speaker.

No, your speaker magnets aren't going to damage your hard drive. While powerful magnets *are* used for wiping the servo tracks on drives, we're talking some serious magnets that are placed directly over the drive. Your speakers' magnets aren't nearly strong enough. Plus, magnet strength drops very quickly with distance.
