A magnetically hard substance is one which can be permanently magnetised using a strong magnetic force. Steel is one such substance. (A magnetically soft substance can only be magnetised temporarily.)
A hard disk drive (HDD) is a fixed storage device that consists of one or more rigid metal platters coated with a metal oxide material. These platters store digital data magnetically and are read/write heads access data on the platters.
The temperature at which metals become soft is called the forging temperature. The forging temperature of nonmagnetic stainless steel is 1150 Celsius or 2102 Fahrenheit and the forging temperature of magnetic stainless steel is 1095 Celsius and 2003 Fahrenheit.
Halite is hard. It can be scratched by a steel file and a knife with difficulty
A typical steel knife would be in the 5-5.5 range on the Mohs scale.

Using a magnetically hard material for an electromagnetic crane can result in difficulty controlling the magnetic field, making it less efficient and potentially causing safety issues. Magnetically hard materials retain their magnetism even after the current is turned off, leading to challenges in releasing the load when needed. This can make the crane more dangerous to operate and less precise in its movements.
Hard magnets are permanent magnets that do not require electricity to retain their magnetism and are not easily demagnetized. They are magnetically charged naturally and can be artificially, too.
If you are referring to RAM, none because it would slow it down. Hard drives and floppies are magnetically written to.

Cold hard steel
a steel bar is a magnetically susceptable material. if you apply a magnetic field through the steel bar, such as applying a DC current through a solenoid winded around it, it will become magnetized. Just rubbing a magnet against the steel bar will help align all the magnetic dipoles in a general direction for it to be considered a magnet.
The hardness of steel is incomprehensible. It is very hard.
