How to Fix Damaged Hard Disk

In layman may be difficult to fix, but technically the damaged hard drive can be repaired, depending on the level of damage.

4 levels, is based on research and my own experience over the handling damage to the hard disk.

Level 1 
Damage that occurred at this level usually caused Bad sectors. To handle this there are several ways and experimental variation, adapted to the hard drive brand and the number of bad sectors.
* For the initial handler can use the command FORMAT C: / C (adjust the drive which will be formatted). / C is used to clean up the cluster which is broken.
* The second step, if not managed can use the Disk Manager program from each hard drive manufacturer.
* If not successful you also can use the software HDDREG, please download on the internet program.
* If not successful try the Low Level Format or Zero Files.
* If you still can not, you can do cutting damaged sector of hard disks which, by dividing it and not use a damaged sector.

Level 2 
The damage at level 2 is Losing Hard Disk Partitioning and Data. This could be caused by a virus or error using utility programs. One is to be considered in hard drive partition to restore the lost, the hard drive capacity and type of file system. Partition with a FAT File System is more easily restored than NTFS or Linux File System.

Level 3 
Erosive damage to the hard drive detected in BIOS but can not be used, always an error message appears when the computer do the POST. This is usually caused FIRMWARE troubled from the hard disk. For these symptoms are more common in Maxtor brand hard drive series with the names of Gods. To fix it you can download the firmware program from the hard drive brand website.

Level 4 
The damage that causes the hard drive is not correctly detected by BIOS and can not be used again. This is the hardest level in my opinion. Due to the repairs we need a little tweaking tooling electronic devices and components inside. Menganggulangi hard drive is not detected by the BIOS in many ways.
* Check electrical current which flows into the hard drive 
* Changing the IC on the mainboard Harddisk 
* Open the Cover Cover hard disk drive and check the position of Head
 * How to reply Extreme damaged hard drive which can be cannibals with the others who harden your hard drive is different, can be a way to replace the mainboard or take her IC.

General Preventive Maintenance Of Laptop

Don't leave your battery unused for long periods of time. Even if you use AC power most of the time, use the battery regularly to keep it in good condition. Switch off your AC adapter when the laptop is not in use. This prevents overcharging. To extend battery life, you can try decreasing the LCD brightness while using your notebook. You can activate the `Standby' and `Hibernation' power­ saving modes, too, for better battery life, you can put off the Wi-Fi when not in use. If you do not use your laptop for extended periods of time-a week or more ­remove the battery pack from the laptop, but only after discharging it fully. No eating and drink­ing near or around your laptop. The least bit of water could short-circuit some sensitive laptop circuits, and render it useless. You may sometimes be tempted to turn your laptop off by simply holding down the power button until it powers down. Although quick, this method is harmful to the laptop and could cause data loss. A hard reboot should only be used as a last resort. Sometimes this is inevitable, for instance, when Windows hangs. But this should not be a regular practice. Don't subject your laptop to jerks and shocks. This will help avoid damage to your hard drive. Preferably, power the notebook off  before moving it from one place to another. External peripherals and accessories such as external opti­cal drives, PC cards and USB keyboard lights draw power from the notebook. Disconnect such devices when not in use. Booting the notebook when it is not connected to a power source draws a lot of power from the battery. Instead of shutting down       your laptop in the middle of a meeting, choose the `Suspend' mode if you wish to use it again after just a short interval. This will       save battery and help you restart your work faster. If you have just shut down your laptop, give it 30 seconds before you start it up again. This ensures that the hard drive has spin  down, and is not subjected to sudden switching on and off. Don’t put on the laptop keeping of cloth or bed because generally the air flow is  from bottom, regular doing so may reduce the life of  laptop circuit. Don’t press very hard the laptop keyboard because, if damaged can cost very high, therefore while playing game use external keyboard.
