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…?!

I wouldn’t expect it to. I think mythbusters did an episode on this, and it took the strength of one of those car lifting magnet cranes to damage an HDD.

So weird, literally just watched this episode last night.
Just a glitch in the matrix
I’d need a banana for scale to see if this is huge or a macro photo of a small thing.
Thats a releaf 😅
“relief” is how that word is spelled. Like belief.
Ok english is not my main language…
All good, I just wanted you to know how it’s spelled. Not angry or upset
It’s alright. We all understood what you meant. Don’t worry about your spelling, this isn’t a test or anything. 🙂
I don’t beleave it
Good greaf
Wait really? I used to work at a place where we cleared out HDDs with a degausser. I'm pretty sure that thing wasn't as strong as a car junkyard magnet.
Degaussers use varying magnetic fields in a specific way, it’s not raw field strength doing the erasing.
I have one in my case, attached to the metal part covering the PSU in a CM silencio case. I have a single 2.5" hdd in the same case, without any issues.
Yea but the problem is my hard disk is in its bracket made from metal and this support gadget is directly on that metal…
I wouldn’t worry. As others has said in this thread; a way more powerful magnet is present inside the HDD. Also fans produce magentic fields to a small degree. Then again, I don’t store anything important on the magnetic drive in my PC, so I’m not risking anything. 🤷♂️
You could always remove the magnet, and glue the support in.
I have to check that out. This gadget is made from metal, not plastic, im not sure if its possible.
.
Yes magnets can affect HDDs. But it needs to be very strong and close to the HDD. I wouldn’t worry unless you are directly attaching it to you HDD and even then it probably won’t do much if anything at all.
Remember HDDs already have strong permanent magnets inside them. Probably way stronger then the one on the bottom of that support.
Fields from magnets can, just depends how strong and this applies to spinning hard drives not SSDs. We had an idiot at work once that decided to store a bunch of magnetic bases on the top of a tower PC. Corrupted the drive. This case there were quite a few of them maybe in a half dozen to a dozen range and they were the strong lockable ones for breadboards.

Ok so here is the situacian. I have rx 6800xt merc that definitly needs some kind of support. But down there is place for two hdds. I have one in top slot. So magnet is directly above 😶 thats why im a bit voried.
Here is another picture, but with hdd in botom slot.

there’s good separation between the magnet and even the topmost hdd position.
you will be fine either way!
Good to hear that, because its not even a 1cm its more like 5mm
Can you give me a link for this product? mine says a little and something like this would make me feel better that it won’t break lol.
It doesnt have any branding and site that i bought it from is local site that operates only in my country… So cant realy give you the exact product name or anything. It just sad gpu holder. But it shouldnt be hard to find now that you know how it looks…
Thank you! 🩵
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.
I can’t tell how strong that magnet is, but I wouldn’t risk it with my data.
See thats the problem. This thing is made from metal and magnet is so strong that it can hold it in place with no problem when pc case is fliped on its side down on the ground horisontaly! If i stick it on fridge it will stick out like a horn or dagger. So thats what makes me conserned. And on top of that, its close to the hard drive, olmost like its placed directly on it.
That doesn’t mean much. Gravity is very weak. The real test is seeing how much weight it can hold.
You would usually need a really strong electromagnet to actually kill a hard drive through magnetism alone.
And what about extended period of time? This thing is siting there and hard drive also for etrnity?
I doubt it would affect anything, it takes a very large magnet to damage a HDD from outside the casing.
LOL You know what will damage a hard drive? A regularly used electric pencil sharpener on top of the case directly over the hard drive for a few years.
