Bad Sectors

Unfortunately bad sectors are the enemy of every computer user in the world. A hard bad sector is a sector on a hard drive that cannot be used due to permanent damage to the surface of the disk. This is not always physical damage (although is often the case) it can be caused by the sector locking and becoming unrecoverable.
A soft bad sector is a bad sector that may be repairable as these are logical errors. This article concentrates on hard bad sectors. Running the check disk utility which is built into the windows operating system should resolve logical errors.
Any data stored on a bad sector when it goes bad is usually lost as the sector becomes unrecoverable but the rest of the drive should function correctly and the data on the drive should be OK.

what are bad sectorsHow did I get bad sectors?

Bad sectors are to be expected on any hard drive and most drives have bad sectors when the drive is first manufactured. Over the lifespan of a hard drive you will get bad sectors through no fault of the user. These are usually dealt with by the operating system and stored and marked as unusable.
Laptop drives also seem to be more susceptible to bad sectors than a desktop computer simple because a laptop is more likely to be moved around increasing the chances of damage as most hard drives have moving parts. The exception to this is solid state drives which have no moving parts.

What are the signs of bad sectors?

The most obvious sign is a dramatic slowdown in your computer. People often attribute a slowdown in their computer to a virus or a lot of junk on their computer but in my experience bad sectors are just as likely to be the culprit. The operating system tries to read data and re-try’s until it times out and moves on. Multiple bad sectors will bring a computer to a grinding halt.



A good way to check this is to look in your event log under system (control panel, administrate tools, event log) If your computer has many bad sectors they may be logged here.
Another common sign is the activity of your hard drive. A hard drive with bad sectors does tend to be much more active. Even when the computer is idle you may see the hard drive light flickering away as it tries to organize or bypass the bad sectors.
You may also receive boot errors when booting your operating system such as files missing or boot records corrupted. These can sometimes be attributed to problems with bad sectors on your hard drive. If you are receiving error messages and unable to boot you may find our “hard drive failure repair and recover data” article useful.

Can I repair bad sectors?

You can not repair hardware bad sectors as they are permanent damage on the disc. Having said that you can perform something called remapping which means the system marks the sectors as bad and knows not to use them to stop your system becoming unstable. Windows has built-in tools that can do this for you called chkdsk.
There are other free tools out there that may be able to repair bad sectors(soft) and remap hard bad sectors such as HDAT2. There are also the tools that come from your hard drive manufacturer.

Avoiding bad sectors in the future

Sometimes no matter what you do you will end up with bad sectors on a drive but there are a few things you can do to minimize the risk.
  • Keep your computer dust free. Use compressed air to clean out tough areas to reach.
  • Always shut down your computer correctly. Turning off the computer by the power socket is a sure fire way to damage your hard drive
  • When moving your computer do so very carefully.
  • Keep your computer cool and well ventilated.
  • Using disk defragmentation software to prevent wear and tear.
  • Malware and viruses can also be a cause of bad sectors. Ensure you run good anti malware software like Malwarebytes Anti-Malware and have a good anti-virus program like Kaspersky Internet Security to keep your computer protected.

TOP 10 MOST COMMON COMPUTER PROBLEMS


TOP 10 MOST COMMON COMPUTER PROBLEMS

Although most complex computer issues at work can often be solved by the business IT support team, there are many other small, but common, issues that occur on a regular basis on a personal computer. The good news is that many problems with computers have simple solutions, and learning to recognize a problem and fix it yourself will save you a lot of time and money. The following are the top 10 common computer problems that you shouldn't panic over.
 
1. The Computer Won’t Start
A computer that suddenly shuts off or has difficulty starting up could have a failing power supply. Check that the computer is plugged into the power point properly and, if that doesn’t work, test the power point with another working device to confirm whether or not there is adequate power.
2. The Screen is Blank
If the computer is on but the screen is blank, there may be an issue with the connection between the computer and the screen. First, check to see if the monitor is plugged into a power point and that the connection between the monitor and computer hard drive is secure. If the problem is on a laptop, then you may need to get a professional to fix it as some of the internal wires may be worn.
3. Abnormally Functioning Operating System or Software
If the operating system or other software is either unresponsive or is acting up, then try restarting your computer and run a virus scan. To avoid having this happen, install reliable anti-virus software.


4. Windows Won’t Boot
If you are having troubles booting Windows, then you may have to reinstall it with the Windows recovery disk.
5. The Screen is Frozen
When you computer freezes, you may have no other option than to reboot and risk losing any unsaved work. Freezes can be a sign of insufficient ram, registry conflicts, corrupt or missing files, or spyware. Press and hold the power button until the computer turns off, then restart it and get to work cleaning up the system so that it doesn’t freeze again.

6. Computer is Slow
If your computer is slower than normal, you can often fix the problem simply by cleaning the hard disk of unwanted files. You can also install a firewall, anti-virus and anti-spyware tools, and schedule regular registry scans. External hard drives are great storage solutions for overtaxed CPU’s, and will help your computer run faster.
7. Strange Noises
A lot of noise coming from your computer is generally a sign of either hardware malfunction or a noisy fan. Hard drives often make noise just before they fail, so you may want to back up information just in case, and fans are very easy to replace.
8. Slow Internet
To improve your Internet browser performance, you need to clear cookies and Internet temporary files frequently. In the Windows search bar, type ‘%temp%’ and hit enter to open the temporary files folder.
9. Overheating
If a computer case lacks a sufficient cooling system, then the computer’s components may start to generate excess heat during operation. To avoid your computer burning itself out, turn it off and let it rest if it’s getting hot. Additionally, you can check the fan to make sure it’s working properly.
10. Dropped Internet Connections
Dropped Internet connections can be very frustrating. Often the problem is simple and may be caused by a bad cable or phone line, which is easy to fix. More serious problems include viruses, a bad network card or modem, or a problem with the driver.

Free Software to Fix Dead Pixel on Monitors [Windows]


Free Software to Fix Dead Pixel on Monitors [Windows]


Even if your screen appears to be working fine, there still can be some dead pixels present which you are not aware of because that pixel always shows up only in a single color. It can be irritating to have dead pixels on your computer monitors.

How to find Dead Pixel:
·         Usually these pixels can be found by showing different colors in full-screen mode.
·         You can simply use paintbrush and create JPEG files of different colors for your screen resolution and display them in slide show mode one after the other to see if there is any dead pixel.
·         You can also try the LCD Pixel Fixer software( link below) and enter 1000 milliseconds delay between color changing to see these dead pixels.
Fixing Dead Pixels:
·         A dead pixel on your monitor/screen, may not be as dead as you think it is.
·         Sometimes these can be easily fixed by just letting your screen to show various colors at that point one after the other for two or three hours.
·         You can also try the LCD Pixel Fixer software which keeps on changing the color of the screen with the delay defined by you.
·         I made this software since I was not able to find anything working for such use on the net when I was annoyed with three dead pixels, so I thought of sharing this software with you.
.
·         Just enter the time delay in milliseconds on the screen you get right after opening the application and press enter or click proceed.
·         To exit simply press the ESC button or press SPACE to change the delay time.
Platform Supported: It requires Windows machines with .Net Framework installed (it’s already installed on most machines)

Microsoft Solution: SQL Server 2000 installation fails with "...previous program installation..." error message


Microsoft Solution: SQL Server 2000 installation fails with "...previous program installation..." error message

Today I came through an article regarding the above mentioned subject, I just wanted to assess the authority it is based on, because it is our own computer which we are playing with. Finally I found one, and my suggestion to you all my dear friends that you should always seek the solution with the authenticated.

SYMPTOMS
When you install SQL Server 2000, this error message may occur:

A previous program installation created pending file operations on the installation machine. You must restart the computer before running setup.

After the error message appears, the installation will not continue until you address the problem.

CAUSE
Pending file rename or delete operations.

WORKAROUND

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.


To work around this problem, depending on the source of the error, you can use any one of the following methods: 

Restart the computer and see if you are able to run the setup. If the restart does not help, use the steps that follow.

Perform these steps and then run the SQL Server 2000 setup again:

Click Start, and then click Run.

In the Open dialog box, type: "Regedit" (without the quotation marks) or "Regedt32" (without the quotation marks)

Click OK.

NOTE: Please make sure that you only delete the value mentioned, not the whole session manager key.

In Registry Editor, expand the following registry subkey:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager 

On the File menu, click Export.

NOTE: In Microsoft Windows 2000, click Export Registry File from the Registry menu.

In the File name text box, type: "Session Manager Key" (without the quotation marks) 

Click Save.
In the right-pane of the Registry Editor window, right-click PendingFileRenameOperations. On the shortcut menu that appears, click Delete.

In the Confirm Value Delete message dialog box that appears, click Yes.
On the File menu, click Exit.

NOTE: In Windows 2000, click Exit on the Registry menu.

Restart the computer.

Using the Registry Editor, verify that the PendingFileRenameOperations registry value is not available.

Note: The PendingFileRenameOperations registry value may be re-created when you restart the computer. If the registry values are re-created, delete the PendingFileRenameOperations registry value again by completing steps a through j, and then run SQL Server 2000 Setup. Do not restart the computer before you run SQL Server 2000 Setup.

Check other control set keys (for example, ControlSet001, ControlSet002, and so forth) for the same values and also delete them.

Identify the virtual memory settings on the computer. If the paging file is too small or if there is no paging file, this error message may occur at startup:
Limited Virtual Memory Your system has no paging file or the paging file is too small.

If the error message occurs, determine the placement of the paging file from the virtual memory settings and give that drive full permissions for the system account.

How to protect your company PCs from Hacking?


Hacking: How to protect your company PCs

WASHINGTON: Small business owners simply need to take two easy steps to ensure they don't become the next victim of a cyberattack- keeping systems up-to-date and setting policies for employees, security experts have said. 

Jason Glassberg, co-founder of Casaba, a security company, pointed out that small businesses are a prime target for computer hackers and scammers largely because they leave themselves vulnerable. 


Glassberg said that hackers prey on any vulnerabilities in a system, rather than targeting particular victims. Because of that, small business owners can't afford to be complacent. 

According to Fox News, experts suggest that one of the main defenses a small business owner can take is making sure all systems are up-to-date. 

That means having patches installed on a regular basis, making sure all antivirus software has the latest installs and that they are current on all versions of software. 

It's also important for the small business owner to set policies in terms of what Websites employees can and cannot visit. 

The business owner needs to be realistic and realize that even if a Website is on the "do not visit" list, someone is going to go there anywhere. 

To protect the computers from getting infected as a result, Dave Aitel, CEO of Immunity, the security penetration and assessment company, says to run ad blockers, the report said. 

According to Jason Glassberg, co-founder of Casaba, a security company, to prevent employees from opening spam mails, Gregg says small businesses should use filtering software that will prevent the email from getting to the employee.
