Hard drive data loss can occur for many reasons. You cannot insure yourself against it, but you can reduce the possibility of such sequence of events. Firstly, you should not overheat the drive. The spinning speed of modern hard drive platters is much higher than it has been before and, thus, it generates even more heat.

Just like unskilled forex trading increases the risk of loosing your investments, in the same way an increase of spinning speed of hard drive increases the chances of disk overheating, which may result in motor failure. Installing a cooler fan will help to avoid overheating.

Shaking and bumping of hard drive are unacceptable since it is sensitive to vibrations and requires delicate handling. That is why you should not forget about basic precautions for handling this device, which by the way is required when working on forex as well. Failing the above, disk heads can be destructed followed by complete data loss. Therefore, you should transport and handle the disk with great care and caution.

It is quite often that we face a situation when we have to purchase a new, larger capacity HDD to move all information from the old one to it. At the same time it is not necessary to get involved into a complicated procedure of reinstallation of operating system or reinstallation of any other software. Experienced specialists from the service centre can professionally and timely move your entire configuration from the old drive to the new one. As a rule, the process of moving the structure can be divided into three stages.

1. The first stage is installation of new hard drive disk into the computer just next to the old one. Making this on an ordinary PC is not a problem, but if we are talking about pocket or mobile computers, here you would have to insert a new storage device into external USB case.

What is SCSI?

SCSI (Small Computer Systems Interface) — is the most popular interface for physically connecting and transferring data between computers and peripheral devices.

First SCSI devices appeared as far back as in 70-ies, when Shugart Company began its R&Ds in the sphere of hard disk new interfaces connections.

Today a SCSI is one of the standards (to be more precise – a set of standards) of internal interface and cedes only to IDE interface in terms of popularity. The main difference from IDE, which is supported by a limited number of specific peripheral devices, is that a general interface SCSI was developed to support different types of internal and external devices. This implies that it is possible to connect internal drives and various external peripheral devices with the help of SCSI adapter: scanners, streamers, plotters, printers and so forth. Perhaps it is the primary advantage of SCSI over IDE. The following are the key advantages of SCSI interface: high speed rate; it is independent of the system bus; connection of 7 to 15 different devices to one channel. Unfortunately, it has a number of disadvantages as well: high cost and relative difficulty in installation and setup.

Symptoms can be conditionally divided into three groups according to the external manifestation of problem:

1) Hard drive is not recognized in BIOS;

2) Hard drive is recognized in BIOS, but is not accessible from operating system;

3) Operating system recognizes the disk, but when accessing data written on it, the system freezes or gives a fatal error message.
