Because computer users are human, the user can be a major cause of computer failure. And we service our computers but in many cases, we operate the computer but know little about the software and hardware components and peripherals.
As this happens, you should ASSUME NOTHING when diagnosing computer problems. We diagnosed a new PC with a video display problems. After a brief look at the video card takes a while to see that the video card is not pushed fully into the adapter slot.
Although I saw the card, I fail to check thoroughly. This leads me to spend more time on issues that are not needed.The thought of a hard drive failure terror attacks in the heart of every computer user.
This is because of hard drive failure can cause loss of valuable data. Here are the most common procedures you should do when you experience hard drive failure.
Common Hard Drive Problems
Hard drive can display problems such as “retry, abort, ignore” or “can not read sectors” while operating. This is an indication that there might be a bad place or not legible on the drive. Reformatting and reinstalling the operating system can usually fix this problem. This will cause you to lose all data on your drive so it is important to always have a good backup your files daily.
There are several good utilities that either you can buy that can fix the problem hard drive without destroying data. The utility Spin-rite is a good utility and only costs $ 200.00 which is a good price if you want to avoid the hassle of reformatting the drive and restore the operating system. Here are some common hard drive problems you have to start from and we will be more specific later.
Use Operating System Utilities
First you may be able to fix the bad spots and errors from your hard drive by performing those PC maintenance in the operating system. Windows has Disk De-fragment and you should run a disk de-fragment after running Scan-disk since scan-disk will need to fix the problems found. After scanning the drive and de-fraging files, run Disk Cleanup to make sure all the junk files deleted.
Check Drive cables and connections
If there is an indication that the drive is receiving power (you do not hear the familiar clicking sound or lights drive not working) check the 4-wire connector from the power supply.
If the connection is secure, you can remove the power supply connector and do two things. You can check to see if there is a voltage with a multi-meter. But that is much faster to connect another 4 wire connector to the drive to see if the drive is working. There is usually an additional connector from the power supply or you can use the connection to the cdrom drive to test the voltage of power supply.
If the connection is showing no or very little voltage (4 volts or less) from the power supply, power supply may be bad. Now check and check all the connections, especially if you are someone else has recently worked on the computer.
If the drive will not boot up …?
Boot the computer with a DOS bootable disk. If you do not have one made, STOP and make one NOW by clicking Start, Settings, Control Panel, Add and Remove Programs, and Startup Disk.
Try to access drive C: by typing DIR C: and press Enter. If you see a directory on drive C: try to make the drive bootable by typing sys a: c: and press Enter. These files must be restored and the drive system can be restored to boot itself.
If this fails, you may have to format and partition the drive with a setup utility that came with your drive or computer.
If the Drive boots but hangs at boot …?
Turn off the computer, open the system unit and remove the ribbon cable at the end of the motherboard. Turn your PC and you’ll get an error message that the drive is bad and in most cases will go into your BIOS. Change the type of hard drive to AUTO and shut down the computer.
Reconnect the ribbon cable and see if the drive is working properly. Setting the drive to be returned and must operate properly.
A hard drive that failed to boot up is also possible to have a bad controller. If the controller is already installed on the hard drive, not much you can do except replace the drive.
