A hard drive contains platters that are magnetic media capable of having the magnetic state of areas on them changed and having this magnetic state retained/maintained. Data is held on a hard drive by representing it in binary form (1s an 0s). The way these 1s and 0s are physically represented on a drive's platter(s) is by having areas (spots) that are magnetically charged or not. The 1's are represented by charged (positive and negative) areas, the 0s are represented by uncharged areas (there is a level of tolerance by which an area is deemed charged or not). When a sector becomes "bad", or is deemed to be so, it is because areas within it no longer appear to be able to maintain a sufficiently magnetized (positive or negative) state (charge) to represent the 1's data in those areas. Bad sectors are marked (flagged) in a table and, when possible, remapped to one of series of spare sectors all hard drives have.

Now, sometimes an area is deemed (flagged) as bad when it may in fact not really be. Perhaps some oddity during the write process caused the spot to be too weakly charged (which really shouldn't happen or at least not often as that is a sign of another problem), rather than it being a case of the actual area on the media being bad in some way. Using the appropriate utility a sector previously marked as bad can be un-marked (taken off the bad list). And you can use one of these utilities to put a sector back in service (so to speak). Nothing is "fixed", just made available for use again as is.

However, if a sector really is bad, really can't be reliably, sufficiently charged or made to hold a charge, then it cannot be fixed by software such as HDD Regenerator seems to claim. The only fixing that might be possible would require a lab/factory. A truely bad sector has some form of damage, its physical properties have changed. Software can't undo this. About the only thing that could/can be done through software is to allow that area of data to be read (recovered) where it otherwise may not be by other software.

You can try the hdd manufactors zero write program. The fdisk and format the drive.
Then using a 98boot disk with scandisk on it, run scandisk /surface on the drive. And if all those bad cluster show up again. It is hdd replacement time.

By the way a note of caution, doing that will remove everything, I mean everything from that drive. It will be a 100% lose.

Another thing is go to www.grc.com and look at the SpinRite product.

Cant fix error


this sounds like a HDD problem, your best is to download a live operating system such as knoppix and boot to it, once in check that you can see the HDD it will be shown as "sda1" gather all data and information you want to keep and reinstall your OS

if you are using windows and you havnt made a recovery disk, then you can either contact the manufacturer to send one out or buy the windows install disk

How to speed up your computer's performance?


Information: There are some few guidelines that you can follow to maintain your computer and keep it running smoothly.

Free Up Disk Space
By freeing disk space, you can improve the performance of your computer. The Disk Cleanup tool helps you free up space on your hard disk. The utility identifies files that you can safely delete, and then enables you to choose whether you want to delete some or all of the identified files.
Use Disk Cleanup to:

• Remove temporary Internet files.
• Remove downloaded program files (such as Microsoft ActiveX controls and Java applets).
• Empty the Recycle Bin.
• Remove Windows temporary files.
• Remove optional Windows components that you don't use.
• Remove installed programs that you no longer use.
Tip: Typically, temporary Internet files take the most amount of space because the browser caches each page you visit for faster access later.
To use Disk Cleanup

1. Click Start, point to All Programs, point to Accessories, point to System Tools, and then click Disk Cleanup. If several drives are available, you might be prompted to specify which drive you want to clean.
Disk Cleanup calculates the amount of space you will be able to free.
2. In the Disk Cleanup for dialog box, scroll through the content of the Files to delete list.
Choose the files that you want to delete.
3. Clear the check boxes for files that you don't want to delete, and then click OK.
4. When prompted to confirm that you want to delete the specified files, click Yes.
After a few minutes, the process completes and the Disk Cleanup dialog box closes, leaving your computer cleaner and performing better.
Speed Up Access to Data
Disk fragmentation slows the overall performance of your system. When files are fragmented, the computer must search the hard disk when the file is opened to piece it back together. The response time can be significantly longer.
Disk Defragmenter is a Windows utility that consolidates fragmented files and folders on your computer's hard disk so that each occupies a single space on the disk. With your files stored neatly end-to-end, without fragmentation, reading and writing to the disk speeds up.
Run Disk Defragmenter
In addition to running Disk Defragmenter at regular intervals, optimally monthly, certain events warrant running the utility outside of the monthly rule of thumb.
You should run Disk Defragmenter under the following circumstances:
• You add a large number of files.
• Your free disk space nears 15 percent.
• You install new programs or a new version of Windows.

To use Disk Defragmenter:
1. Click Start, point to All Programs, point to Accessories, point to System Tools, and then click Disk Defragmenter.
Click Analyze to start the Disk Defragmenter.
2. In the Disk Defragmenter dialog box, click the drives that you want to defragment, and then click the Analyze button.
After the disk is analyzed, a dialog box appears, letting you know whether you should defragment the analyzed drives.
Tip: You should analyze a volume before defragmenting it to get an estimate of how long the defragmentation process will take.
3. To defragment the selected drive or drives, click the Defragment button.
After the defragmentation is complete, Disk Defragmenter displays the results.
4. To display detailed information about the defragmented disk or partition, click View Report.
5. To close the View Report dialog box, click Close.
6. To close the Disk Defragmenter utility, click the Close button on the title bar of the window.
Detect and Repair Disk Errors
In addition to running Disk Cleanup and Disk Defragmenter to optimize the performance of your computer, you can check the integrity of the files stored on your hard disk by running the Error Checking utility.
As you use your hard drive, it can develop bad sectors. Bad sectors slow down hard disk performance and sometimes make data writing (such as file saving) difficult, or even impossible. The Error Checking utility scans the hard drive for bad sectors, and scans for file system errors to see whether certain files or folders are misplaced.
If you use your computer daily, you should try to run this utility weekly to help prevent data loss.
To run the Error Checking utility:
Important: Be sure to close all files before running the Error-Checking utility.
1. Click Start, and then click My Computer.
2. In the My Computer window, right-click the hard disk you want to search for bad sectors, and then click Properties.
3. In the Properties dialog box, click the Tools tab.
4. Click the Check Now button.
5. In the Check Disk dialog box, select the Scan for and attempt recovery of bad sectors check box, and then click Start.
In most circumstances, select Scan for and attempt recovery of bad sectors.
6. If bad sectors are found, choose to fix them.
Tip: Only select the Automatically fix file system errors check box if you think that your disk contains bad sectors.

    Hi,
    Check the hard disk cable or a huge bad secter in your hard disk,
    you need to repair ,
    1. I think there are too many bad sectors in your 'HDD'. The reason you did not use for a long days or electricity problem (horrible breakable power supply).You will always use UPS. To repair the HDD, you should need a bootable DM .I don't know, which hdd you are using. So you will use ontrack bootable dm follow the step >

    Download from bellow link, for ontrack dm

    http://www.downtr.net/297918-ontrack-easyrecovery-professional-621.html

    Mazor problem is most of the user, burn ISO file in data mode and the result, it could not run in boot time.
    Burn the iso file, under image burning option from any nero .

    2. Restart >press F2/F10/Del( for entry in the BIOS)>Set the cd/dvd as 1st priority.

    (It will start aotomatically from cd )If create any problem footing the cd , follow the bellow link for set boot piority.

    http://www.windowsreinstall.com/articles/bios/

    3. Ensure that your Bootable dm cd, in cd rom.
    4. Boot from cd will be appear then hit Enter as quick as possible.


    5. All it will be possible, if you know dos other wise it will be difficult.
    6. DON'T PANIC,I hope, you will can do it

    7. Type that letter where the dm software in the cd.
    8. Type in dos mode. e.g. if your two partition c: d : so your dm will be in e:.
    9.type e: and enter , for observation type= dir and enter >now you can see is there ontrack or dm (directy or folder) have or not try it once after one
    10 If have ontrack in that folder type=cd (space) ontrack>cd (space) dm hit enter .
    11 If all ok type dm and enter
    12.Enter
    13.Advance installation
    14.Maintence
    15.Uttility
    16.Zerrofil
    16.Yes
    17. It will take 8 to 10 hours don't panic all data will be lost
    17. With this processes your hdd can be ok.
    18. And after complete all the program installs os again

    5 ways to speed up your computer


    By following a few simple guidelines, you can maintain your computer and keep it running smoothly. This article discusses how to use the tools available in Windows 7, Vista, and XP Service Pack 3 (SP3) to more efficiently maintain your computer and safeguard your privacy when you're online.

    1. Free up disk spaceThe Disk Cleanup tool helps you free up space on your hard disk to improve the performance of your computer. The tool identifies files that you can safely delete, and then enables you to choose whether you want to delete some or all of the identified files.
    Use Disk Cleanup to:

    • Empty the Recycle Bin.
    • Remove Windows temporary files such as error reports.
    • Remove optional Windows components that you don't use.
    • Remove installed programs that you no longer use.
    • Remove unused restore points and shadow copies from System Restore.
    Tip: Typically, temporary Internet files take the most amount of space because the browser caches each page you visit for faster access later.


    2. Speed up access to dataDisk fragmentation slows the overall performance of your system. When files are fragmented, the computer must search the hard disk when the file is opened to piece it back together. The response time can be significantly longer.

    When to run Disk Defragmenter
    In addition to running Disk Defragmenter at regular intervals—monthly is optimal—there are other times you should run it too, such as when:
    • You add a large number of files.
    • Your free disk space totals 15 percent or less.
    • You install new programs or a new version of Windows.

    3. Detect and repair disk errorsIn addition to running Disk Cleanup and Disk Defragmenter to optimize the performance of your computer, you can check the integrity of the files stored on your hard disk by running the Error Checking utility.

    Tip: Only select the "Automatically fix file system errors" check box if you think that your disk contains bad sectors.


    4. Protect your computer against spywareSpyware collects personal information without letting you know and without asking for permission. From the Web sites you visit to usernames and passwords, spyware can put you and your confidential information at risk. In addition to privacy concerns, spyware can hamper your computer's performance. To combat spyware, you might want to consider using Microsoft Windows Defender, which is included in Windows 7 and Windows Vista, and is available as a free download for Microsoft XP SP2. Alternatively, there are other free anti-spyware software programs available.

    5. Learn all about ReadyBoostIf you're using Windows 7 or Windows Vista, you can use ReadyBoost to speed up your system. A new concept in adding memory to a system, it allows you to use non-volatile flash memory—like a USB flash drive or a memory card—to improve performance without having to add additional memory.
