Can Magnets Destroy Hard Drives? 5 HDD Facts A few years ago, a technology expert at Forbes.com responded to a reader who had dropped a fridge magnet on his hard drive and wondered if it could do damage. The expert reported that a really strong magnet (with a pull force of at least 450 pounds, [...]
Magnetic Had Disk Drive Computers have a (secondary) storage device called a disk drive, It is where all your apps are stored. There are currently two types of storage device, the magnetic hard disk drive and the solid state disk drive. A computer (unopened) A computer (opened) - Magnetic hard disk shown A working magnetic [...]
