Fix bad hard disk Sector
Hard drive is a storage medium that is very important on the computer. Unfortunately, a limited service life. Broken to the hard disk can be caused by several things. For sample:
· Power supply is inadequate and damage the hard drive and the motor controller.
· Hard falls and mechanical damage inside or minimum occurs bad sectors.
· Too often brought brought unprotected make-platter hard drive is damaged due to excessive shock.
· The temperature of the heat in the HDD makes the condition of the hard drive in an unstable environment.
· Conditions MTBF / lifespan hard drive, has been reached and will be damaged.
It can still be done to improve the hard disk bad sector affected is the only condition in which the disk is spinning, the state of the disk controller still works.
But this state is divided again, if you would to use the HDD bad sector affected. Problems cause bad sectors is one of the most common damage. Conditions of damage by bad sectors are distinguished by three circumstances.
· The condition where the disk platter wear. In this condition, the hard drive is already not
could be used. The longer the hard drive getting damaged and no longer useful to be used as a storage medium.
· Platter worn condition but has not yet reached a critical condition. This condition can be said to be stable enough for the hard drive. Chances hard drive can still be improved because the platter is still possible dilow level.
· Conditions platter worn, either severe or mild conditions but there is damage in the cluster 0 (the location where the disk partition information is stored). This condition does not allow the HDD repaired.
Talking about the state of the HDD to be repaired only allow improvement in the condition to 2, where the surface of the disk is still stable but there is minor damage in several places.
The Purpose
· Attempts to use the HDD bad sectors
· Setting the location of damage to the elimination of bad sectors.
stages 1
Before doing the next stage should use stage 1 to ensure the condition of the damaged hard drive platter. To know it is hard to be performed LOW LEVEL FORMAT (LLF). LLF can be done from the BIOS or software. For BIOS, some old PC as generation Pentium 486 or (586) has the option LLF. Or you can use the software LLF. To got the software could be taken at Site LLF hard drive maker. Or search for files like hddutil.exe utility (from Maxtor - MaxLLF.exe) and wipe.exe 1.0c version 2.5.96
The function of software LLF is deleting all partitions good information, the data in the hard disk bad sector and information. This software is also useful to correct errors on FAT 32 partition creation of Windows Fdisk.
After running the program LLF, the disk would be absolutely clean as the condition was first used.
Warning: Use of LLF software would be erase all the data on your hard drive
stages 2
The next process is to try and error method. Stages for this session were:
a. Creating a hard disk partition: With the FDISK program with one partition, either primary or extended partition. For the primary could be done with single HDD, but if would the hard drive as an extended, takes a hard drive as the boot process and has a primary partition (partition to boot ukan Melak).
b. Format hard drive: With FORMAT C: / C. Addition of command / C to run the option checks if there are bad sectors. During the process of formatting check on the percentage of how much damage the hard drive. This can be seen in the picture below this hotel.
When FORMAT program featuring Trying to recover allocation unit xxx, meaning that the program is examining the conditions in which they occur bad sector HDD. Assumptions on the following test is 1.2 GB Seagate hard drive with 2 small damage location and approximate percentage figures shown by the FORMAT program:
c. Create a partition back: With FDISK, remove all the partitions on your hard drive before, and re-create the appropriate partition record the damage. Assumptions on the bottom picture is partitioning with Primary and Extended partitions. In the Primary partition is not visible and only shown extended partition. The division in the picture at the bottom is on drive D and F (22MB and 12 MB) discarded because there are bad sectors. While the E and G (758MB and 81MB) is a drive that is still in good condition and can be used.
If you are stubborn enough to fix your bad sectors, can also be done by repeating the search location tryerror with bad sectors on your hard disk smaller stages, eg multiple partitions to minimize the possibility of wasting space on the partition that will be discarded. The more determined to seek broken in a place where there is a bad sector is getting better, only in this way will take longer though the result is quite satisfactory to minimize hard drive location where the damage occurred.
d. To ascertain what the bad sectors already located on the hard drive partition that will be disposed of, do format the entire drive letter with the command FORMAT / C. If indeed there are bad sectors on the partition disposed (assuming the test is bad sectors on the drive letter D and F), later on the partition could be immediately discarded. But if something goes wrong, such broken is not bad sectors in the partition that will be disposed of, but there is the partition that will be used, you have to repeat the process from the start by removing the partition where there are errors in the partition dividing the bad sector affected. the thing that keep in mind: Making the partitioning is done from beginning to end, for example, C, D, E and later. To discard the partition using the opposite way ie from Z to C. Errors in disposing and create partitions random mess will mess up the system hard drive partition.
e. The next process is to remove the partition that is not used anymore. After examination from the FORMAT program, then the next process is to delete the partition that contains bad sectors. In the picture below is: throw Stage 2 FDISK to partition the drive letter D and E. For E and G is a partition of the drive letter that will be used.
f. At the end of the stage you can check re-partition the hard drive with option 4 (Display partitisi) on FDISK, the example in the figure below is the remaining 3 drives: C as the primary partition (not shown), two extended partitions are still good and partitions contains bad sectors has been removed.
g. The end of the process. You have a hard disk with improved conditions due to bad sectors. Letter divided on the C drive as the Primary partition and used as a boot, D (758MB) and E (81MB) is partition 2 and 3 in the extended partition.
If you are not satisfied with the search for bad sectors, later on you could repeat the above prosesur. To perform these tips should already know the procedure in backing for the partition with FDISK program.
It should be noted at this tip is, be careful to use LLF program. We recommend using a single drive to use this program. LOW LEVEL FORMAT mistake doing the hard drive is very fatal and can not dikembalikin to its former condition.
For the hard disk bad sector affected hard disk should use conditions are not too severe or there are bad sectors in some places and not sporadic spread. Damage to many places (sporadic bad sectors) on the hard drive will make it difficult for search places where there is bad sectors.
