Secure your warehouse: Data security in computer systems – part 1
In the previous article (“Logistyka” 5/02), I described the basic threats that often lead to the loss of valuable data. This time, I will cover early warning methods in the event of an imminent hard drive failure.
A bit of theory to start with…
A hard drive is a very precise device, manufactured in laboratory conditions. Its operating principle seems relatively simple: rotate spinning platters with ferromagnetic coatings, and write and read data from them using magnetoresistive heads mounted on special arms.
For decades, production technology has been refined, and drive capacity and speed have been increased.
The article comes from the magazine “Logistyka” 2002/6.
