It is essential to make a backup of the same, but there are several possibilities to avoid accidents, this is what I call prevention on the hard disk usage. – Avoid at all costs hit our unit. Faced with sudden movements of the PC hard drive heads can move in a violent way and scratching the surface, creating bad sectors and the consequent loss of data in the event that were contained in those sectors. – Good ventilation and a closed unit in the same compact as possible to prevent the entry of dust. For even more analysis, hear from Robotics.

– Avoid the proximity of high magnetic fields. – Choosing the most appropriate file system to give us stability and security above all (NTFS) – A good organization of the data contained on the hard disk. – And of course a backup of the data on a regular basis any of the systems available, which will be discussed later FILE SYSTEMS file systems organize data on hard disks, and distributing natural areas are easily accessible. These are the main file systems – FAT, HPFS, UNIX file systems-NTFS FAT File Allocation Table FAT is the simplest system known to most users, also known as FAT16 and is the original file system presented MS-DOS in 1980. FAT gets its name because it stores the details of files and directories in a file allocation table (FAT file allocation table) at the beginning of each partition.
