The computer's hard drive is an important part, because it uses the long-term storage of data. Use magnetic surfaces on which data is stored digitally. He was in his early years, the removable media on the root disk, such as floppy drives, and others, but over time the units and the average (the real custodians of information) to a whole body.
The writing and reading functions into your hard disk to the head, a small electromagnet assembly is performed. Thecapable of every disk sector for the stored data. There are a number of disks in a spindle, which allows a rapid rotation of the head to read and write data quickly consumer is located. The speed of the hard drive is one of the most important characterizations.
There are three interfaces to a hard drive that is used to install on your system. The first is the IDE connector. It 'used to transfer data to and from the unit. There is usually a red line that tells youin which direction you should point the cable. The red line should always be on the side of the supply network. The new units are unable to make mistakes because they are limited by a small object captured. The network connection is that the hard disk is connected to the mains. The jumper block is the last interface to use. It 'did for the unit is functioning properly over the place in which the cable is set. Usually when you install itslave - the end of the cable, the jumper must be set to master, and in other situations. There is also a function of cable select, but can not work properly with some motherboards, so it is better to be adjusted manually for him.
After the successful installation of a hard disk, you should verify if the BIOS can correct. This is the BIOS setup, which is done by pressing a special key after sending the second computer may begin. This is usually the place where theRepair work begins. If you do not recognize the hard drive can be manually and make sure that the installation is done correctly you should consider a possible hardware problem. Try listening to the sound of the hard drive. The spinning causes a constant low level noise is usually detectable, if you listen carefully. This will tell you if the unit is actually running or not. If there is a scratching noise, you should immediately shut down and do your running for the repair of a professional, becauseprobably the damage is too mechanical. The interior of the body of the hard disk of dust and free air, and so you should never try to open them if they are not a specialist.
If the hard disk is permanently damaged, there is little chance for recovery. This is achieved by removing the media from the disk and puts it on a special disc made for the recovery, but if there is physical damage on the turntable, the data is probably beyond recovery. For this reason, it is necessaryimportant information together in more than one location. If you have many partitions the data set will not help if the other side are all on a hard drive. Always be taken seriously, as you can store and use the data on your hard drive.
Now I will discuss some information for people who have more interest can be restored to your hard drive. The first is an MS-DOS command called debugging. It will operate in a very direct machine code. The understanding of this code is veryimportant part of this process. For example, you could give D40: 0, and this will give you a few lines of information. The first tells you all ports that are in your computer. Of course, you will see it only if the codes F8 03, COM1, is white F8 02 - COM2 and so on. Use the command "q" to exit the shell.
Other useful information you need to know is why some software is not supported are possible. For example, Windows 95 does not support hard drives over 32GB. It 'was designed to not need this kind of support when it was created. It 'the same with the file systems - FAT16 is not possible if the partition size is limited to 4 GB. You should always think about what is supported, because this is your last line.
The closure of the hard drive is another interesting topic. It 'made by a simple blocking and unblocking commands. Like for instance, if you lock the partition with the letter C, you should block type c: and unlock c: aunlock. This can cause problems if the disc is locked, if you require the installation of software, operating system or try other activities, the special write access.
Let me conclude this article with recovering deleted information on lost or missing files from your hard drive. This is very important to know because you could save a crucial fact. First make sure that the files were actually deleted. Try to find all of the units, because sometimes it is possible thathave simply been postponed. Check if you have a backup of the file. If you have one, it will be easier to recover from it. Many operating systems are rubbish, and if you accidentally delete a file you can find it there too. If you can not restore the file as follows and if it is actually deleted, you should know that only the link was deleted from the file system. Now the important thing is not to write more data on this drive, because you want to restore the file isAs free space and can be completely deleted when you write data to it.
To recover lost data using freeware software like Undelete Plus or to purchase a better, if you need. This is also a good time to check for professional help.
