Storage or magnetic hard disk and floppy disks, as they are now known increasingly offer nearly exponentially computer memory on the user’s needs today, it is necessary for video, audio and image files. Respect for the same physical quantity Footprint and hard drives were first, they were massively at the moment of 1 TB (1 Tera-bytes) for a single disk, a relatively short time frames.

Moore’s Law, as is often said, predictions, the pace of processor speed, and leads to the conclusion that the speed of the CPU would double every 18 months (just what he did, it was created by M . Moore of Intel), there was such a “right” or “roadmap” for hard disk drives. All these additional storage capacity was very welcome by computer, but it was a compromise with storage capacities increasing and the entire lifetime of the media, and especially the reliability Media, do you think all major media.

Spinning magnetic storage media are vulnerable to weakness in several areas, some of which are inherent to the internal structure and design, other issues are not external. Hard disk drive is based on an electro-mechanical technology hubs often with glass or ceramic covered then a process called stammer, this layer coding and decodes a head stack assembly highly accurate and repeatable precision , a modern classic Hard Drive is less than 1 micron.

The big internal problems, which can be instrumental in the failure and data loss, Head Crash, heat and power cycling.

Head Crash

This is, if the header mounting, in direct contact with a surface area of the surface of the media, it is not for the (hard drive, in some technology enables the head in the ground on the Domestic media), contact can be damage, if the damage to the head, and / or there may be other contaminants or nitrogen oxides, on the hard drive of the case, Chief Crash symptoms usually manifest by unusual noises such as clicking, ticking, scratchy or clunking the media should be immediately stopped for no possibility of data recovery. Area density of bits per inch and ousted the technology, so that, inevitably, the media are very precise tolerances.

Heat

The ambient temperature of the system and the hard drive itself, but also be concerned with data integrity and longevity of your hard drive a simple fan can save you from data loss, hard disk, such as Media, both internal and external, are sensitive to errors in heat.

Power cycling

Power Cycle media on the hard drive can be successful that the disk can not be completely eliminated, and a serious matter of the inverter.

There is nothing more frustrating than losing the most important documents or data, so that you have spent a lot of time to implement. If you have suffered a loss, as you know, as it is touching. The best way to prevent loss of data, it is ready to be for him. For example, backing up your important data on a CD or DVD external drive with uninterruptible power supply (UPS) and the hard drives in the fans are of the utmost importance that the actions can save a lot of ills head.

In an emergency,

If yourself in the unfortunate situation, but probably not on the hard drive and are not able to restore your data, and then in another way professional services to recover data, which can help to get your data. These services are relatively cheap for the data you want to restore probable. On top of charge, they usually only if it manages to recover your data.
