Magnetic screwdrivers - yay or nay for building computers?

So here's something I've always wondered...is it okay to use magnetic screwdrivers when building a computer?

I'd imagine the magnetic field would screw up the hard drive or something, but I've never had any problems. I haven't used one in awhile, however, because I'm not sure if it hurts anything. I don't use a heavy-duty magnetic screwdriver, just one of the basic ones with a magnetic tip. They're so useful because I'm always dropping screws in hard-to-reach places and some screws are wicked hard to hold in straight without the aid of a magnetic tip.

So...is there any scientific proof as to whether or not using a a magnetic screwdriver is bad for your computer? Have you ever had any problems? What do you think? Vote now or forever hold your peace!

So no problem on the hard drive then? Anything else it might affect?
 
The magnetic tip isn't strong enough to affect a hard drive in the slightest bit -- your normal fridge magnet won't do much either. A screwdriver might be strong enough to mess with a floppy or zip disk, but no one uses those anymore, right? I think Dan's Data had an article or two on why normal magnets won't affect your hard drives.
 
I always use magnetic screwdrivers when assembling a PC.. infact if I can't find a magnetic screwdriver when assembling a PC I get really grumpy!!
(people around work like to borrow things a lot)

it's FINE.

family not so bad for me, but my screwdriver set went missing at work for a few days a while ago.. not cool!

Of course, those magnets are magnetized on their faces, and their fields extend only a very short distance from the surface. But even so, magnetized screwdrivers usually aren't very strong, and the hard drive's case keeps them away from the platters.
 
There is no serious risk to useing a magnetic over a regular... id consider scratching the mobo while removing a crappy arse heatsink clip to be more of a risk (im so glad intel ditched those on their stock coolers)
 
This is a little off topic, but I have a funny story about laptops and magnets.

At my old job (Best Buy) I was working on a computer near a cash register. The register counter had one of those security tag demagnetizers built into it. Well, when I was working on the laptop, the register would beep (signifying something was demagnetized), the HDD would make a loud click, and the LCD would flicker. It did this a few times before I could figure out what was going on. I moved the laptop away, fixed whatever problem the customer had, and the laptop was fine. So I'm pretty sure computers can take a decent jolt of EM before things start really acting screwy.
 
The anti mag screwdriver bias took hold in the days of floppy disks (you do remember the 8" ones, don't you 😉 ) - and has hung on tight ever since. As long as you use your brain for something besides keeping your skull from collapsing, you'll be OK. Keep them away from floppy disks and though you probably couldn't really hurt a CRT monitor with one - no sense chancing it.

search dansdata.com for letters answering this. you'd need an electromagnet a millimeter away from the drive platter to do any damage.

Just take a regular screwdriver and swipe it across a speaker magnet a couple of times. It will induce a magnetic field that is plenty strong enough for computer screws.

Lasts for months.

In addition, it is even weaker than a standard magnetized screwdriver so you have to worry about it even less.
