Abstract

A method and an apparatus for protecting a disc of a computer facility, includes coupling a control device between a CPU and the disc, separating the disc into one or more protected areas and one or more unprotected areas, and shielding the protected areas, to allow only predetermined command from the control device to access into the protected area, and to prevent the protected area from being accessed and attacked by unauthorized persons and computer viruses. A key device may be coupled to the control device, to control and to shield the protected area via the control device.

Description

1282923 V. INSTRUCTIONS INSTRUCTIONS (1) [Technical field to which the invention pertains] There is a way to store or operate a computer data, and a hidden device and method for computer data. First, [previous technology], the computer used in the market before the Ξ璁ί must be inserted one or one with a . or hard;: a disc player for storing data, and these disks 〇r μ The haiku system uses an indexed organization method (jnde ed ed magnetic; ?; world? an丨Z at丨0 n ) to manage files. This method divides the heart into multiple magnets...; "*,::: "When you use an index table (FAT) name and you want to store it in an empty disk or hard drive, the file Y) f will be stored in the root directory (R00T DI RE CTOR is a single ^ ' and its The content of the broadcast is broken up, and the size of each cluster is f into the disk or hard disk drive. The content of the magnetic cluster size is calculated and the first magnetic cluster index of the slot is stored. In the file name and attribute of the value table 2, the remaining magnetic cluster index values are recorded in the index and the project. Second, in the file management system, if the index table or the combination is unable to reply, all the data in the file. Will lose the operating system, or the protective software can be conditionally D 1 s κ ^ DH recorded 'but S ή - like the inside of the computer Required disk software such as F delete ’ F〇RMAT

In the case of some index tables or root directories that have been damaged or currently on the market, PC~c IL·L is seen as a disk protection software, such as trend file or sweep memory, which is an example. Scanning with software • Various types of infected viruses are used to compare various viruses in order to find unbroken disks or hard disks::::: Move two: There are still some protection methods in these viruses. Remove or sweep after the disease. However, the anti-virus database has the disadvantage of being the best, that is, it must be kept up-to-date and can't be detected and used to & ..., smuggle or get rid of these viruses. The active destruction of the female-like female must use the hardware anti-mite + A eve soft company's recovery card in the market, the original card can only be used to monitor the Β 〇 〇 S interrupted side, the North soft male software Writer of important magnetic area, = prevent hackers from directly outputting to disk or hard drive: 疋J: 嶋 or program hacker's entry? And it will still be easy to get to the law to prevent this. There is also a kind of magnetic gap protection technology that has been developed. For example, the invention of the towel in Taiwan, please call the disk protection 89125173, that is, the certificate work 57 The magnetic gap between the magnetic zone and the magnetic zone is stored: 枓:, the magnetic gap originally exists to prevent the head from being read, and the shell = 2 can be reserved for the next other magnetic zone. However, when the disk drive ♦After picking up a speed, the protection data stored in the track gap is ^= some
