File Systems Data Security
FILE SYSTEMS. DATA security or what say the importance of making good use of our hard drives, the loss of information contained in them can prove to be disastrous. It is essential to make a backup copy of them, but there are several possibilities to avoid accidents, this is what I call prevention on the use of the hard disk. -Avoid at all costs hitting our unit. Against sudden movements of the PC hard disk heads can scroll violently on the surface and scratching it, creating faulty and sectors with the consequent loss of data in the event that they were contained in these sectors. -Good ventilation of the unit and a closed compact to avoid as far as possible the entry of dust. -Avoid the proximity of high intensity magnetic fields. -Choice of the most suitable file system that offers us above all stability and security (NTFS) – a good organization of the data contained on the hard disk.
– And of course a backup data contained on a regular basis in any of the available systems, which later file systems file systems organize data on hard disks, distributing them in physical areas that are easily accessible. These are the main file systems: – FAT – HPFS – file UNIX – NTFS FAT allocation table FAT file systems is the simplest system known by the majority of users, also known as FAT16 and is the original file system presented with MS-DOS in 1980. FAT gets its name because it stores the details of files and directories on a file allocation table (file allocation table FAT) at the beginning of each partition. Each cluster has one entry in the FAT which tells the system what files and folders are stored. For the files that occupy more than one cluster, the FAT contains all the information in order to rebuild that file from your cluster chain and load it into memory.
