computer hard drive is an important element, because you use to store data long term. It uses magnetic surfaces on which data is stored digitally. In his early years, the media was removed from the main drive as the floppy drive, and others, but with time and the disk (actual custodian of information) has become a whole body.
performed the functions of reading and writing to disk by the leader, the assembly of a small electromagnet. It is able to reach all sectors of a hard disk where data is stored. There are many slices in a shaft that rotate to quickly get the baby to read and write data quickly is placed. The speed of the drive is one of the most important characteristics.
There are three interfaces on a hard disk that you use to install on your system. The first is the IDE connector. It is used to transfer data to and from the drive. Usually there is a red line that tells you what direction you should point the cable. The red line should always be on the side of the current connection. In the new drives you will find it impossible not to be confused, because it has been limited by a small element of the blood. The power connector is what connects the hard drive and power supply. The jumper block is the last interface to use. It is made to the drive in an appropriate manner of the cables in the work place it is fastened to define. Usually when you install it on the end of the jumper cable must be checked on the situation and in others – the slaves. There is also a function of the “Cable Select” but it can not function properly with certain motherboards and therefore it is preferable that it be set manually.
After proper installation of a hard drive you should check whether the BIOS correctly displayed. This is done with the BIOS configuration where you start by pressing a special touch seconds after your computer to enter. This is usually the place where the repair begins. If you can not see the hard drive manually and make sure that the installation is in a good, you should do is to consider a possible hardware problem. Listen to the sound of the hard disk. The mill provides a constant low sound that is detectable in the general, if you listen closely. This will tell you whether the drive is running or not. If it’s a scratch, you should immediately turn off the system and take your hard drive for the repair of a professional because it is likely that the damage was is mechanical. The body in the hard disk of dust and air, and therefore you should never try to open when you are not a specialist.
If your hard disk is permanently damaged, there is a small chance of data recovery. This is done by removing the media player and a special drive to recover data done, but if there is physical damage to the adjusted data probably irretrievably. Therefore, you should always put important data in more than one location. If you have multiple partitions, data on the other will not help if they are all on a single disk. Always serious, the storage and use of data take from your hard drive.
Now I will list some information for people who are more interested in repairing the disk. The first thing is a command prompt in MS-DOS called debugging. It allows you to work in a very direct way with the help of computer code. The understanding of this code is a very important part of this process. For example, you can D40: 0, and this will give you a few lines of information. The first shows all ports that are in your computer. Of course, you will find that if you know the code as F8 03 is, COM1, F8, 02 – COM2 and so on. To exit the command “q” to the shell.
Other useful information you need to know is why some software does not support are possible. For example, Windows 95 does not support hard drives larger than 32GB. It is designed because there is no need for this type of support when it was created. It’s the same thing with file systems – you can not FAT16 if the partition is more than 4 GB. One should always consider what is being supported because it is your limit.
The disk lock is a more interesting question. It is simple commands to lock and unlock from. For example, like if you lock the score on the letter C, you must lock on, type c: and c unlock: unlock. You may experience problems if the drive is locked when you install the software, operating system or other activity that requires special access to try writing.
I close this section with information on lost, missing or deleted files from your hard disk. This is very important to know because they can save important data. First make sure that the files were deleted. Try it in each player, because sometimes it is possible that they are simply moved. Check if you have a backup file. If you have one, it will be easier to make from it again. Many operating systems have trash and if you accidentally delete a file, you can find it again. If you can not recover the file as follows, and when it is actually deleted, you should know that only the link was deleted from the system file. Now the important thing is not to write more data on the disc because the file you are trying to retrieve, and marked as free space can be completely deleted when you write data to it.
To restore the lost data using freeware tools such as Undelete Plus or a better buy if you have the need. There is also a good time, the use of a specialist.
