Improve Harddisk Bad Sector

Improve Harddisk Bad Sector


Hard disk storage media is very important on the computer. Unfortunately, the use of a limited age. Damage to the hard drive can be caused by several things.

For example:

* Power supply is inadequate and damaged hard drives and motor controllers.
* Harddisk falls and mechanical damage occurs inside or at least bad sectors.
* Too often carry no safety brought to platter hard disk damaged due to excessive shocks.
* The temperature in the hot disk to disk conditions in an unstable environment.
* Condition MTBF / old hard drive, has been reached and will be damaged.



It still can be done to improve the hard disk bad sector affected is the only state where the disk is still spinning, it is still working hard disk controller. But this situation is still divided again, if you want to use the hard disk bad sector affected.

Cause of bad sector problem is one of the damage that often occurs. Damage by bad sectors are distinguished by the 3 state.
Conditions where the disk platter aus. In this condition it is not hard drive can be used. More and more damaged hard disk and no longer useful to use as media storage.

Condition platter worn but not yet reached a critical condition. This condition can be said is stable enough to drive. Possible hard drive can still be improved because the platter is still possible dilow level.

Platter of wear conditions, both conditions are severe or mild, but there is damage in cluster 0 (the location where the disk partition information is stored). This condition does not allow disk repaired.

Discuss the state of your hard disk to be repaired only possible improvement in the condition 2, where the disk is still stable but there is minor damage in several tempat.Tujuan

Before doing the next stage should be using the stage 1 to ensure the condition of the damaged hard disk platter. To find this hard disk should be LOW LEVEL FORMAT (LLF). LLF can be done from the BIOS or software. For the BIOS, some old PCs such as next generation Pentium 486 or (586) have the option LLF. Can use the software or LLF. LLF for the software can be taken at Site disk makers. Or search utilities such as file hddutil.exe (from Maxtor - MaxLLF.exe) and wipe.exe version 1.0c 05/02/96.

The function of the software to delete the entire LLF is good information partitions, data and information in hard disk bad sector. This software is also useful to improve a manufacturing fault on a FAT partition from Windows 32 Fdisk.

After running the program LLF, the disk will be totally clean as the condition was first used.

Warning: Use of software LLF will erase all data in the harddiskTahapan 2

The next process is to try and error method. Stage for this session are:

1. Create partition disk: With FDISK program with only 1 partition, either primary or extended partition. For the primary can be done with a single hard disk, but if want the hard drive as extended, required a hard drive as the boot process and have a primary partition (the partition to boot).
2. Format your hard disk: With the FORMAT C: / C. Adding command / C to run the option checks if there bad sectors. During the formatting process check on what percentage of hard drive damage. This was shown in the picture below.
3. Create a partition again: With FDISK, remove all partitions in the disk before, and make appropriate re-partition damage records. Assumptions on the picture below is the design of the Primary partition and Extended partitions. In the Primary partition is not visible and only shown extended partition. The division in the picture below 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.
4. To ascertain what was bad sector is located on the disk partition to be removed, do the format on the drive letter with the command FORMAT / C. If there are bad sectors on the partition removed (assuming the test is bad sectors on the drive letter D and F), then the partition can be immediately discarded. But if anything goes wrong, such damage is not in the bad sector to be disposed partitions but the partitions are in use, you must repeat the process from start to remove the partition where there are errors in the dividing partition bad sectors affected. Things to remember: Making a partition made from beginning to end, such as C, D, E and next. To remove the partition using the opposite way from Z to C. Errors in waste and making wild random partitions will disrupt the system disk partition.
5. The next process is to remove the partition that is not used anymore. After examination with FORMAT program, then the next process is to remove the partition that contains bad sectors. In the picture below are: Stage 2 waste FDISK to partition the drive letter D and E. For E and G is a partition drive letter that will be used.
6. At the end of the stage you can check hard disk partition with option 4 (Display partitisi) FDISK program, for example in the figure below are the remaining 3 drives: C as the primary partition (not visible), 2 extended partitions are still good and bad partitions containing sector have been removed.
7. End of the process. You have a disk with the improved conditions due to bad sectors. Letter on the C drive shared as a Primary partition and used as a boot, D (758MB) and E (81MB) is a partition into 2 and 3 in the extended partition.

When the program displays FORMAT Trying to recover allocation unit xxxxxx, meaning the program was checking the condition in which the disk is going bad sectors. The assumption in the following test is a 1.2 GB Seagate hard drive with 2 small locations and estimate the damage percentage figures shown by the program FORMAT: Display Conditions on the percentage of program formats that can be used

* 0-20% Good 20%
* Bad sector 21% Discharge
* 22-89% Good 67%
* Bad sector 91% Discharge
* Both 91-100% 9%

If you are determined enough to fix your bad sectors, can also be done with a try-error repeat the search with the location of bad sectors on the disk is smaller stages, such as making a lot of partitions to minimize the possibility of wasted space on that partition will be discarded. The more determined to find the place where the damage occurs, the better bad sector, only this way will require a longer time, although the results are quite satisfactory to minimize damage to the location where the disk occurred.

If you are not satisfied with the results looking for bad sectors, then you can repeat the above prosesur. Tips for doing this should already know the procedure in making the partition with FDISK program.

That it should be noted in this tip is, be careful in the use of LLF programs. We recommend using a single drive to use this program. Mistakes do LOW LEVEL FORMAT on the hard drive is very fatal and can not dikembalikin like shape.

For hard disk bad sector affected hard disk should use the condition are too severe or there are bad sectors in some places and not sporadic spread. Damage in many places (sporadic bad sectors) on the hard drive will make it difficult search occurs where bad sectors.
