I don't know if this is of any use, but, once, years ago, I made the horrible mistake of putting a running hard drive upside-down on top of a running power supply while having the rig running out of the case. As a result of this, the drive got a bunch of sector errors. I still have it, it spins up fine, but I don't think it's trustworthy. I was darn lucky that the whole reason I was running the rig was to secure erase that drive. Well, it looks like I more-or-less succeeded in doing that!

Note, however, the differences between the scenarios. This hard drive of mine was put right smack on top of a power supply.

Then your subwoofer may be magnetically shielded.

Wrong.

That is one impressive display picture.

So if this is a myth, then why is it in my manual?

It 100% will not effect your drives. I have taken an electromagnet used for wiping old school video tape and ran it over a hard drive, did nothing to the data, I also took a very strong rare earth magnet and ran it over a hard drive, again, nothing the data was completely intact.

The only thing an un-sheilded speaker might damage is a CRT display, and even that is not permanent.

Well reading the rest of the thread looks like we have all come to a consensus. I like TwoCables but you did one thing I hate, and that is believing something with no evidence and when evidence to the contrary is pointed out. The word for it is magical thinking. We are all pretty left brained people here, we hopefully rely on facts and science (i.e. testing it out). I've tested it out and modern hard drives are just not vulnerable to any kind of magnet that you would normally have around your house.

Your fine.

I ruined an original Xbox by setting it on top on my Energy Encore 8 subwoofer as I was dusting and re arraigning my room.
I turned on the Xbox and it started wigging out and the picture was all screwed up . It dawned on me that it must have been the magnet from the sub.
The Xbox was never the same again.

I store a couple of HDDs very near a classic 8" JBL sub with ginormous magnets for a 8" ...
Nothing happened. Keep in mind that magnet is powerful is enough to nearly overwhelm a neodymium magnet that you find in harddisks @ 1/2 INCH!

It's just like the nonsense you hear while taking IT diploma that they would say "Keep harddisks away from sunlight as that has magnetism"

Sounds like there is a story behind that one. Did someone say this to you?

If so you should have said, "are you asking me to stick my drives where the sun don't shine?"

Yeah, during a lecture. Of which i replied "Where the sun don't shine you'll be asking me not to put my drives?"
Let's just say the lecture ended prematurely and i got another negative rep point again tongue.gif
