More recently, anyone who considers himself a rational computer users use to store important data CDs.For example, many people still have a collection of favorite movies and games recorded on CD and DVD.Conventionally, it can be assumed that the well-known video received a second incarnation in the form of discs.
At the same time, the area of media is one of the fastest growing.CD were replaced DVD, subsequently superseded CDs technology blue ray (Blu-ray).And now a permanent decline in the value of flash memory indicates that the approach is completely new, revolutionary way of storing information: suffice it to say that the guaranteed term preservation of recorded data is at least 10 years old (unattainable time budget for disks).But in the future.
Currently, in parallel with the development of flash devices, there is another promising way to create a home collection or copies of important data.This use as backup information to the second hard disk drive (HDD).It's simple: cost per gigabyte of disk space of the hard drive is now significantly reduced, making it affordable for even a person with average income.The obvious benefit of a second hard drive to the CD - it is protection from scratches, higher reliability, fast search of the necessary data.
However, more people began to do so, the more often the question is asked why Windows 7 will not see a second hard drive.Now there are three types of interface hard drives: IDE, SATA and USB.The first was almost not released since motherboards lost native support for IDE.The latter represents the most popular at the present time, type, and the third - a prerogative of external devices.
If Windows 7 does not see an external hard drive, the problem may be in the port.Many laptops Controller USB - is a "sore spot", because a high percentage of repair service center falls on those faults.
If Windows 7 does not see the hard drive, do not panic - in many cases, unable to recover on their own.Imagine a situation: the user is connected to a computer hard drive and load the operating system Windows.But by opening "My Computer", another drive letter has not seen.The cause can be both hardware and software.The program, due to which Windows 7 is not seeing the hard drive, includes:
- channel port to which the device is disabled in the computer's BIOS.Check that all the SATA ports and USB have been exposed to the state «Enable»;
- attached a new hard drive is not prepared as needed and does not contain sections, as a result of Windows 7 does not see the hard drive.Download, run and partition disks using software Paragon Partition Magic, Acronis Disc Director or is not entirely correct, but effective - began installing Windows 7 at one stage will be invited to perform the requested breakdown (wheels do not confuse!);
- error within the operating system.There is a rare and unpredictable.You can try to install the driver on the motherboard.If there is no result, then you need to reinstall;
- on non-standard disk file system.For example, create a Linux system disk will be invisible to Windows.Eliminates re-broken at the desired system;
- too much.Not all of the system board and can work with such devices.
Hardware reasons why Windows 7 is not seeing the hard disk:
- damaged the interface cable that connects the computer and hard drive.Replace with new check.To SATA cable is recommended with metal latches: reliability is higher and the price differs slightly;
- problems with power contacts.When you turn on the drive does not spin up (you can hear the noise from it), then definitely a hardware problem.Check the power cord.At the external USB hard drive is particularly noteworthy power supply;
- when you turn on the device and then distributed from a continuous knock.With high probability the drive needs to be replaced;
- defective port.Connect to other free connectors or test on a different computer.
