Can magnet damage hard disk?
(lemmy.wtf)
I have a device like this and it supports heavy gpu inside my pc. Wery usefull and nicly built thing made from metal. But the consern is it has a magnet on botom side, so it sticks to metal surfece inside the case. Wery usefull again but my hard disk is under that metal surfice. So i wonder can it corupt data or damage hdd itself..?!
It's always possible, but in my experience, the magnets in those graphics card stands aren't strong enough to hurt the data in a hard drive slotted below them. (Let's also remember that fans containing magnets are often placed near hard drives.)
If you're concerned, you could always replace the magnet with a rubber foot, or replace the whole stand with nonmagnetic cylinder like a cut-down paper towel spool. The graphics card's weight will probably hold it in place.
In any case, I recommend regularly making incremental backups of your data. Hard drives occasionally corrupt data and eventually die even when no magnets are around.
They aren't strong enough to affect the data on a HDD if it were directly attached to the hard drive itself. It takes a pretty hefty magnet to do that.
