You are correct, it won't wipe it. At work we have a degausser for wiping disk drives so powerful that when we use it we have to put warning signs in the hall ten feet away. Doesn't affect solid state media. We're buying a device (NSA approvedl) that will pulverize solid state devices into 2mm particles.BigGuy wrote:I'm pretty certain this is incorrect. Older mediums such as tape and hard drives use a magnetic medium in which the direction of atoms are switched using a magnetic write head. Obviously a magnet will affect such a device. It only requires a field strong enough to switch the orientation of an atom with in the matrix.Glockster wrote:Yup. All memory cards can be wiped with a magnet.tomtexan wrote: Will the magnet do any good since there isn't any tape in the SD card?
Information stored on an SD card is by electrical charge in a solid state circuit. The gate in a solid state transistor is in effect a tiny capacitor. It would require a magnet strong enough to literally rip the electron off of the atom. That would take some magnet.A hammer would be a much more cost effective way to destroy the drive. If you just want to erase it, stick it your compouter and wipe it.Bill Frank, executive director of the CompactFlash Association. "A magnet powerful enough to disturb the electrons in flash would be powerful enough to suck the iron out of your blood cells
