Fixing Bad Sectors On Hard Disk

Problem of Bad Sector

While running your computer, you may receive error messages suggesting your hard disk might contain bad sectors. The errors are typically flagged as "CRC" or "Cyclic Redundancy Error". Some of your data files are missing, unreadable or corrupted and it takes forever or impossible to access certain files and folders. This may be a cause of bad sector problems. Sectors are pie-sliced divisions of a hard disk. And a bad sector is a sector on the disk which data cannot be written or read due to a physical damage or inconsistencies of parity checking bits on disk. Any data that is written or stored on that area is likely to be lost or corrupted. Data residing on the rest of the disk may be unaffected and the disk is considerably usable if the bad sectors are few.


Bad sectors are mainly due to the magnetic weakening of the domain and mechanical faults. Over time, the magnetic areas of a disk lose its magnetism and hence its inability to retain data. Such bad sectors have the tendency to spread and are usually non-repairable. Mechanical faults include physical shocks to the disk, abrupt power shutdowns and disruptions during read-write operations. Head crash can also cause bad sectors and lead to permanent data loss on the disk. When bad sectors spread, it can result in system instability when important system files are destroyed. Mild corrupted data however can be corrected by most file system utilities.


Unknown to most, the bad sectors could some times be due to bad parity checking bits written on disk. Most modern disk while storing data will transparently store parity bits together with the data. When the data is read, the parity bits are also retrieved and compared to ensure the data integrity. This goes on without the knowledge of normal user. When the parity bits are corrupted for some reasons, it will result in bad sector errors. In this case, through some proprietary recovery software, ADRC could actually repair the bad sectors without loss of data by correcting or rewriting the corrupted parity bits on disk.


Very often, bad sectors are manifested as a result of failing Read Write head. When the Read Write heads fail to read and interpret the magnetic signals normally, the same kind of bad sectors errors could occur. Frequently, bad sectors are also early signs of disk crash as it deteriorates over time.


Solution to Bad Sector Problem If the disk is still working well, important data should be backed up immediately to avoid further data loss. If the system respond is virtually "hanging" to a standstill and you have valuable data, the best option is to consult a data recovery specialist without doing this yourself.


Commonly, a full format process should be able to "mask" the bad sectors or earmark the bad sectors in file allocation table. One could continue to use the disk while the operating system will take notice of the location of bad sectors and avoid them altogether.


Another common CHKDSK utility provided by Windows Operating System may help to detect and mark for bad sectors. During a surface scan, it attempts to write data to that sector and then read back what it wrote. If the two do not match, the sector is marked as bad as it does not maintain data integrity. The operating system will note the particular sector and avoid writing new data onto that area of disk. After which, the bad sector will be remapped to a special sector on the drive which is reserved for this purpose.


For Windows 98, ME users, follow these steps:


    * To do this, click Start, point to Programs
    * Point to Accessories, point to System Tools and select ScanDisk
    * Select the Thorough option and click Automatically Fix Errors
    * Click Start




For Windows XP/2000 users, follow these steps:


    * On the desktop, double click on My Computer
    * Right click and select Properties on the erroneous drive
    * Open the Tool Tab
    * Select Check Now under Error Checking

select the option to Automatic Fix File System Errors and Scan For And Attempt Recovery For Bad Sectors

 
*CHKDSK offers 2 modes of scanning:


      Error Checking


      This mode scans your computer's files and folders. It searches and repairs any minor corrupted files and inconsistencies it detects.

Surface Scan
This mode scans every sector of the disk and identifies bad sectors. When a bad sector is detected, CHKDSK will automatically mark it as bad and the system will refrain from writing further data into that sector. The bad sectors will then be remapped with working ones on the disk. Due to the intensive nature of the scan, surface scan mode typically takes very long time to perform. Time range can stretch from a few hours to a few days.


    * Click Start
It must be pointed out here that one must use CHKDSK with extreme care because if the disk is failing imminently, such operation may stress the disk to a point of complete failure. Put it ironically, if you have a good working disk, try it. If you think your disk is failing imminently, , refrain from using CHKDSK.

Understanding registry errors

What’s the main cause of a slow PC? Why the computers always get crash? If we are to talk an average of what I go on, I will take about what is registry. The registry is known as the core of Windows system. In short, the registry is a database which records the settings of your computer. It brings convenience to Windows system but also gives people troubles. This nervous system is very sensitive and prone to get corrupted. All computer behavior can be recorded in registry.

Even worse, your computer will freezes up a lot.
There is no worse than getting a virus on your computer. The virus can randomly change computer setting to reach his aim. While the virus modifies the registry, it slows your computer. The virus does nothing but make your computer a mess.
All above can be concluded as registry errors happen. It is very important to fix registry errors right now. I think you can not fix the error manually from a computer novice or a computer expert. Also David who has more than 10 years computer experience suggest we do not repair registry errors ourselves because a small mistake can destroy the whole system.
Fortunately, RegTool was designed to help people fix registry errors in one click. This program can also backup the registry in the case you delete useful registry entry. It is the most safe registry cleaner on the market. Are you still suffering the slow computer? I think you can experience this wonderful computer maintain tool.

Why your PC run slowly?

Many people have this problem. A new computer with height configuration but run slowly.
It is so strange that your PC run slow like a snail.Most time you get out of memory. The CPU utilization rate was 100% when you only run a small program. What’s worse, you run a game such like WOW, your PC will freezing. How terrible a thing it is. But you still find that your RAM is 2G not a poor 218M.
Why your computer get a bad performance? Below we share some information about this.
In short, there are two reasons, software and hardware.
Software problem:
1 virus infect:
most new computer do not have an anti virus software. Computer security will not get guarantee. Viruses cause the computer work efficiency, causing frequent crash. You can install Kaspersky.
2 Initialization file destruction:
Because of Windows 9X startup needs System.ini, Win.ini and registry file. So if your registry get corrupt, you will get


3 File missing:
Because of Windows 9X startup needs a Command.com, Io, Msdos, etc, documents, if these files destroyed or error deleting, you need to reinstall the system.
4 Hard disk space not enough or too much fragment.
5 Uninstall software improperly: If delete directly not uninstall in control panel, you can not remove the file in the registry. Cause the system become unstable.
Hardware problem:
1 Cooling system is bad: CPU cooling is related to the stability of computer.Make sure you have a stable cooling system.
2 Software and Hardware not compatible: Such as 3D max and some special software always get problem.
3 The CPU over clocking Hardware
4 Hardware resource conflicts: sound card setting get conflict causing abnormal error. In addition, other equipment, DMA or port conflicts will cause this problem.
