Facts

-Hard drives are infinitely re-writable with no residual “damage” to the hard disk itself, but it is possible, with the right technology to reconstruct information on a hard drive that has been wiped clean or over-written.


-Even calculators and cash registers can have a hard drive to store relatively permanent information that can be retrieved, changed, and stored again on the drive.


-The size and speed of the hard drive in a system is directly proportional to the efficient working of that system. A larger hard drive with a faster processing speed will work more efficiently than a smaller, slower hard drive.
